Using the sum or difference formula, the exact values of sine, cosine, and tangent of the angle 105° (which can be expressed as the sum of 60° and 45°) can be calculated as follows: sine(105°) = (√6 + √2)/4, cosine(105°) = (√6 - √2)/4, and tangent(105°) = (√6 + √2)/(√6 - √2).



To find the exact values of sine, cosine, and tangent of 105°, we can utilize the sum or difference formulas for trigonometric functions. By recognizing that 105° can be expressed as the sum of 60° and 45°, we can apply these formulas to determine the exact values.For sine, we use the sum formula: sin(A + B) = sin(A)cos(B) + cos(A)sin(B). Plugging in the values of sin(60°), cos(45°), cos(60°), and sin(45°), we can calculate sin(105°) as (√6 + √2)/4.

Similarly, for cosine, we apply the sum formula: cos(A + B) = cos(A)cos(B) - sin(A)sin(B). Substituting the values of cos(60°), cos(45°), sin(60°), and sin(45°), we can calculate cos(105°) as (√6 - √2)/4.Lastly, for tangent, we use the tangent sum formula: tan(A + B) = (tan(A) + tan(B))/(1 - tan(A)tan(B)). Substituting the values of tan(60°), tan(45°), and simplifying the expression, we can determine tan(105°) as (√6 + √2)/(√6 - √2).

The option that represents the integral of the given function is option `(c) ln(2 + 3VX) + c`.

The given problem is about finding the integral of the function. We are to find `∫v tan³v dx`. To solve this problem, we will have to use integration by substitution. So, let u = tan v, then du/dv = sec²v or dv = du/sec²v. Now, we will have to substitute v with u as u = tan v, which gives v = tan⁻¹u. Substituting `v = tan⁻¹u` and `dv = du/sec²v` in the given integral, we get ∫ tan³v dv = ∫u³du/[(1 + u²)²]We can now apply partial fraction decomposition to split this into integrals with simpler forms:1/[(1 + u²)²] = A/(1 + u²) + B/(1 + u²)²where A and B are constants. Multiplying both sides by the denominator, we get 1 = A(1 + u²) + B (1) Letting u = 0, we get A = 1. Now letting u = I, we get B = -1/2.So, 1/[(1 + u²)²] = 1/(1 + u²) - 1/2(1 + u²)².Now, substituting this back into the integral we get ∫u³du/[(1 + u²)²] = ∫ u³du/(1 + u²) - 1/2 ∫ u³du/(1 + u²)².Now, we can apply integration by substitution to solve the two integrals on the right-hand side of the above equation. For the first integral, let u = x² + 1 and for the second integral, let u = tan⁻¹(x). Substituting these values in the respective integrals, we get (1/2) ln(x² + 1) + (x/2) (x² + 1) - (1/2) ln(x² + 1) - tan⁻¹(x) - (x/2) (1 + x²) c = (x/2) (x² + 1) - tan⁻¹(x) + c. Hence, the answer is (x/2) (x² + 1) - tan⁻¹(x) + c. Therefore, the option that represents the integral of the given function is option `(c) ln(2 + 3VX) + c`.

The antiderivative of (24x^3 + 18x) / (2 + 3x)^2 is ln(2 + 3x) + c, where c is the constant of integration.

To find the antiderivative of the given expression, we can use the power rule for integration and the chain rule. The power rule states that the antiderivative of x^n is (1/(n+1)) * x^(n+1), where n is any real number except -1. Applying the power rule, we have:

∫(24x^3 + 18x) / (2 + 3x)^2 dx

First, let's simplify the denominator by expanding (2 + 3x)^2:

∫(24x^3 + 18x) / (4 + 12x + 9x^2) dx

Now, we can split the fraction into two separate fractions:

∫(24x^3 / (4 + 12x + 9x^2)) dx + ∫(18x / (4 + 12x + 9x^2)) dx

For the first fraction, we can rewrite it as:

∫(24x^3 / ((2 + 3x)^2)) dx

Let u = 2 + 3x. Differentiating both sides with respect to x, we get du = 3dx. Rearranging, we have dx = du/3. Substituting these values into the integral, we get:

∫(8(u - 2)^3 / u^2) * (1/3) du

Simplifying the expression, we have:

(8/3) ∫((u - 2)^3 / u^2) du

Expanding (u - 2)^3, we get:

(8/3) ∫(u^3 - 6u^2 + 12u - 8) / u^2 du

Using the power rule for integration, we integrate each term separately:

(8/3) ∫(u^3 / u^2) du - (8/3) ∫(6u^2 / u^2) du + (8/3) ∫(12u / u^2) du - (8/3) ∫(8 / u^2) du

Simplifying further:

(8/3) ∫u du - (8/3) ∫6 du + (8/3) ∫(12 / u) du - (8/3) ∫(8 / u^2) du

Evaluating each integral, we get:

(8/3) * (u^2 / 2) - (8/3) * (6u) + (8/3) * (12ln|u|) - (8/3) * (-8/u) + c

Substituting back u = 2 + 3x and simplifying, we have:

(4/3) * (2 + 3x)^2 - 16(2 + 3x) + 32ln|2 + 3x| + 64/(2 + 3x) + c

Simplifying further:

(4/3) * (4 + 12x + 9x^2) - 32 - 48x + 32ln|2 + 3x| + 64/(2 + 3x) + c

Expanding and rearranging terms, we get:

The given sequence can be represented as An = 3 + (-1)^(n/2) for even values of n, and Bn = 1 + n/n^2 for odd values of n.

For even values of n, An = 3 + (-1)^(n/2). Here, (-1)^(n/2) alternates between 1 and -1 as n increases. So, for even values of n, the term An will be 3 + 1 = 4, and for odd values of n, the term An will be 3 + (-1) = 2.

For odd values of n, Bn = 1 + n/n^2. Simplifying this expression, we have Bn = 1 + 1/n. As n increases, the value of 1/n approaches 0, so the term Bn will approach 1.

The limit is equal to 1, the Ratio Test is inconclusive. We cannot determine whether the series converges or diverges based on the Ratio Test alone.

lim n→∞ (1 + 0) = 1

So, the limit of an/(an+1) as n approaches infinity is 1.

To determine the convergence of the series Σ (-1)^n / (7n^3 + 37), we can use the Ratio Test.

Using the Ratio Test, we compute the limit:

lim n→∞ |(a_{n+1}) / (a_n)|

where a_n = (-1)^n / (7n^3 + 37).

Let's calculate this limit:

lim n→∞ |((-1)^(n+1) / (7(n+1)^3 + 37)) / ((-1)^n / (7n^3 + 37))|

Simplifying, we get:

lim n→∞ |(-1)^(n+1) / (-1)^n| * |(7n^3 + 37) / (7(n+1)^3 + 37)|

The term (-1)^(n+1) / (-1)^n alternates between -1 and 1, so the absolute value becomes 1.

lim n→∞ |(7n^3 + 37) / (7(n+1)^3 + 37)|

Expanding the denominator, we have:

lim n→∞ |(7n^3 + 37) / (7(n^3 + 3n^2 + 3n + 1) + 37)|

lim n→∞ |(7n^3 + 37) / (7n^3 + 21n^2 + 21n + 7 + 37)|

Canceling out the common terms, we get:

lim n→∞ |1 / (1 + (21n^2 + 21n + 7) / (7n^3 + 37))|

As n approaches infinity, the terms with lower degree become negligible compared to the highest degree term, which is n^3. Therefore, we can ignore them in the limit.

lim n→∞ |1 / (1 + (21n^2 + 21n + 7) / (7n^3 + 37))| ≈ |1 / (1 + 0)| = 1

Since the limit is equal to 1, the Ratio Test is inconclusive. We cannot determine whether the series converges or diverges based on the Ratio Test alone.

To evaluate the limit of an/(an+1) as n approaches infinity, we can substitute the expression for an:

lim n→∞ ((-1)^n / (7n^3 + 37)) / ((-1)^(n+1) / (7(n+1)^3 + 37))

Simplifying, we get:

lim n→∞ ((-1)^n / (7n^3 + 37)) * ((7(n+1)^3 + 37) / (-1)^(n+1))

=(-1)^n * (7(n+1)^3 + 37) / (7n^3 + 37)

Since the terms (-1)^n and (-1)^(n+1) alternate between -1 and 1, the limit is equal to:

lim n→∞ (7(n+1)^3 + 37) / (7n^3 + 37)

Expanding the numerator and denominator, we have:

lim n→∞ (7(n^3 + 3n^2 + 3n + 1) + 37) / (7n^3 + 37)

lim n→∞ (7n^3 + 21n^2 + 21n + 7 + 37) / (7n^3 + 37)

Canceling out the common terms, we get:

lim n→∞ (1 + (21n^2 + 21n + 7) / (7n^3 + 37))

As n approaches infinity, the terms with lower degree become negligible compared to the highest degree term, which is n^3. Therefore, we can ignore them in the limit.

lim n→∞ (1 + 0) = 1

So, the limit of an/(an+1) as n approaches infinity is 1.

The area between the curves f(x) = = e -0.2x and g(x) = 1.4x + 1 from x = 0 to x = 4 can  be given as  Area = ∫[0,4] (f(x) – g(x)) dx = ∫[0,4] (e^(-0.2x) – (1.4x + 1)) dx.

To find the area between the curves f(x) = e^(-0.2x) and g(x) = 1.4x + 1 from x = 0 to x = 4, we need to calculate the definite integral of the difference between the two functions over the given interval:

Area = ∫[0,4] (f(x) – g(x)) dx.

First, let’s determine which function represents the top curve and which represents the bottom curve. We can compare the y-values of the two functions for different values of x within the interval [0, 4].

When x = 0, we have f(0) = e^(-0.2*0) = 1 and g(0) = 1. Therefore, both functions have the same value at x = 0.

For larger values of x, such as x = 4, we find f(4) = e^(-0.2*4) ≈ 0.67032 and g(4) = 1.4(4) + 1 = 6.4.

Comparing these values, we see that f(4) < g(4), indicating that f(x) is the bottom curve and g(x) is the top curve.

Now we can proceed to calculate the area using the definite integral:

Area = ∫[0,4] (f(x) – g(x)) dx = ∫[0,4] (e^(-0.2x) – (1.4x + 1)) dx.

The extremum of the function f(x, y) = x^2 + 4y^2 - 4xy subject to the constraint x + y = 9 is a maximum at the point (0, 9).

To find the extremum of the function f(x, y) = x^2 + 4y^2 - 4xy subject to the constraint x + y = 9, we can use the method of Lagrange multipliers. The method involves finding critical points of the function while considering the constraint equation.

Let's define the Lagrangian function L as follows:

L(x, y, λ) = f(x, y) - λ(g(x, y))

where g(x, y) represents the constraint equation, g(x, y) = x + y - 9, and λ is the Lagrange multiplier.

We need to find the critical points of L, which occur when the partial derivatives of L with respect to x, y, and λ are all zero.

∂L/∂x = 2x - 4y - λ = 0 .............. (1)

∂L/∂y = 8y - 4x - λ = 0 .............. (2)

∂L/∂λ = x + y - 9 = 0 .............. (3)

Solving equations (1) and (2) simultaneously, we have:

2x - 4y - λ = 0 .............. (1)

-4x + 8y - λ = 0 .............. (2)

Multiplying equation (2) by -1, we get:

4x - 8y + λ = 0 .............. (2')

Adding equations (1) and (2'), we eliminate the λ term:

6x = 0

x = 0

Substituting x = 0 into equation (3), we find:

0 + y - 9 = 0

y = 9

So, we have one critical point at (x, y) = (0, 9).

To determine whether this critical point is a maximum or minimum, we can use the second partial derivative test. However, before doing so, let's check the boundary points of the constraint equation x + y = 9.

If we set y = 0, we get x = 9. So we have another point at (x, y) = (9, 0).

Now, we can evaluate the function f(x, y) = x^2 + 4y^2 - 4xy at the critical point (0, 9) and the boundary point (9, 0).

f(0, 9) = (0)^2 + 4(9)^2 - 4(0)(9) = 324

f(9, 0) = (9)^2 + 4(0)^2 - 4(9)(0) = 81

Comparing these values, we see that f(0, 9) = 324 > f(9, 0) = 81.

Therefore, the extremum of the function f(x, y) = x^2 + 4y^2 - 4xy subject to the constraint x + y = 9 is a maximum at the point (0, 9).

The estimated value of integral I using Simpson's rule with four strips is approximately 116.0007.

To estimate the integral I using Simpson's rule with four strips, we can use the following formula S = (h/3) * [f(x0) + 4f(x1) + 2f(x2) + 4f(x3) + 2f(x4) + f(x5)]

Where:

h is the width of each strip, which can be calculated as h = (b - a) / n, where n is the number of strips (in this case, n = 4), and a and b are the lower and upper limits of integration, respectively.

f(xi) represents the function values at each of the x-values corresponding to the equally spaced points within the integration interval.

Given the values of f(x) at x = 1.0, 3.0, 5.0, 7.0, and 9.0, we can apply Simpson's rule to estimate integral I.

Using the formula, we have:

h = (9.0 - 1.0) / 4 = 2.0

Substituting the values into the formula:

S = (2.0/3) * [6.0000 + 4(9.3944) + 2(12.8769) + 4(16.4174) + 2(20.0000)]

S = (2/3) * [6.0000 + 37.5776 + 25.7538 + 65.6696 + 40.0000]

S = (2/3) * [174.0010]

Evaluating these derivatives at the point P(-1, 2, -9), we have:

∂z/∂x = 6(-1) + 3(2) = -6 + 6 = 0

∂z/∂y = 3(-1) = -3

The equation of the tangent plane can be written as:

0(x - (-1)) - 3(y - 2) + (z - (-9)) = 0

0x - 0y - 3y + z + 9 = 0

-3y + z + 9 = 0

2x + y - 9z = -1

Therefore, the equation of the tangent plane at the point P(-1, 2, -9) for the surface defined by z = 3x^2 + 3xy is 2x + y - 9z = -1.

Using the elimination method to find a general solution for the given linear ordinary differential, we get x = ∫ [(7et + 2e) / 12] dt + C and y = et - 2x + C.

To find a general solution for the given linear system using the elimination method, we'll start by manipulating the equations to eliminate one of the variables. Let's work through the steps:

Given equations:

2x' + y - 2y = et ...(1)

x + y + 2x + y = e ...(2)

Multiply equation (2) by 2 to make the coefficients of x equal in both equations:

2x + 2y + 4x + 2y = 2e

Simplify:

6x + 4y = 2e ...(3)

Add equations (1) and (3) to eliminate x:

2x' + y - 2y + 6x + 4y = et + 2e

Simplify:

6x' + 3y = et + 2e ...(4)

Multiply equation (1) by 3 to make the coefficients of y equal in both equations:

6x' + 3y - 6y = 3et

Simplify:

6x' - 3y = 3et ...(5)

Add equations (4) and (5) to eliminate y:

6x' + 3y - 6y + 6x' - 3y = et + 2e + 3et

Simplify:

12x' = 4et + 2e + 3et

Simplify further:

12x' = 7et + 2e ...(6)

Divide equation (6) by 12 to isolate x':

x' = (7et + 2e) / 12

Therefore, the general solution for the given linear system is:

x = ∫ [(7et + 2e) / 12] dt + C

y = et - 2x + C

Here, C represents the constant of integration.

To evaluate the circular function sin θ for the angle θ, we can use the coordinates of the point on the unit circle corresponding to that angle. In this case, the point P(-1/2, y) lies on the unit circle in the third quadrant.

Since P lies on the unit circle, we can determine the value of y using the Pythagorean theorem:

y^2 + (-1/2)^2 = 1^2

y^2 + 1/4 = 1

y^2 = 1 - 1/4

y^2 = 3/4

y = ±√(3/4)

y = ±√3/2

Since P is in the third quadrant, y is negative. Therefore, y = -√3/2.

Now, let's find the angle θ in standard position using the x and y coordinates of P:

cos θ = x

cos θ = -1/2

Since P is in the third quadrant and cos θ = -1/2, we can determine that θ is π radians.

Finally, we can evaluate the circular function sin θ:

sin θ = y

sin θ = -√3/2

Therefore, sin θ = -√3/2.

The domain of the function is [−30,30] or (-30,30).

What is the domain of a function?

The domain of a function is the set of all possible input values (or independent variables) for which the function is defined. It represents the set of values over which the function is meaningful and can be evaluated.

The given function is [tex]y=80\sqrt{ 900-x^{2}} +8-48x[/tex]. By analyzing the function, we can gather the following pertinent information:

1.The function is a combination of two components:[tex]80\sqrt{900-x^{2} }[/tex]​ and 8−48x.

2.The first component,[tex]80\sqrt{900-x^{2} }[/tex] ​, represents a semi-circle centered at the origin (0, 0) with a radius of 30 units.

3.The second component,8−48x, represents a linear function with a negative slope of -48 and a y-intercept of 8.

4.The function is defined for values of x that make the expression [tex]900-x^{2}[/tex] non-negative, since  the square root of a number is not negative.

5.To find the domain of the function, we need to consider the values that satisfy the inequality [tex]900-x^{2}\geq 0[/tex].

6.Solving the inequality, we have [tex]x^2\leq 900[/tex], which implies that x is between -30 and 30 (inclusive).

7.Therefore, the domain of the function is [−30,30] or (-30,30).

The logs are written in subscript form to avoid ambiguity in the expressions.

(a) log, 7 + log, 3 = log₂0 x

We can solve the above expression using the following formula:

loga + logb = log(ab)log₂0 x = 1 (Because 20=1)

Therefore,log7 + log3 = log(7 × 3) = log21 (applying the first formula)

Therefore, log21 = log1 + log2+log5 (Because 21 = 1 × 2 × 5)

Therefore, the final expression becomes

log 21 = log 1 + log 2 + log 5(b) log, 5 - log, log, 3²

Here, we use the following formula:

loga - logb = log(a/b)We can further simplify the expression log, 3² = 2log3

Therefore, the expression becomes

log5 - 2log3 = log5/3²(c) logg -- 5log,0 32

Here, we use the following formula:

logb a = logc a / logc b

Therefore, the expression becomes

logg ([tex]2^5[/tex]) - 5logg ([tex]2^5[/tex]) = 0

Therefore, logg ([tex]2^5[/tex]) (1 - 5) = 0

Therefore, logg ([tex]2^5[/tex]) = 0 or logg 32 = 0

Therefore, g^0 = 32Therefore, g = 1

The function f(x) = x² - 16 has a removable discontinuity at x = 4 due to the following reasons: A removable discontinuity, also known as a removable singularity or removable point, occurs in a function when there is a hole or gap at a specific point, but the limit of the function exists and is finite at that point.

1. Of(4) and lim f(x) are finite, but are not equal: The value of f(4) is undefined as it leads to division by zero in the function, resulting in an "undefined" or "not-a-number" (NaN) output. However, when we calculate the limit of f(x) as x approaches 4, we find that lim f(x) exists and is finite. This indicates that there is a removable discontinuity at x = 4.

2. f(4) is undefined: As mentioned earlier, plugging x = 4 into the function leads to an undefined result. This could be due to a factor that cancels out in the limit calculation, but not at x = 4 itself.

These factors collectively indicate that f(x) has a removable discontinuity at x = 4, where the function is not defined, but the limit exists and is finite.

Step by step explanation:

(3! + 0!) / (2! x 1!) = (6 + 1) / (2 x 1) = 7 / 2

The function f(x) = 8x(x²-4)² has a domain of all real numbers except x = -2 and x = 2. There are no vertical asymptotes, and the horizontal asymptote is y = 0.

The critical points of f are x = -2 and x = 2, and the function behaves differently on each side of these points. The curve is increasing on (-∞, -2) and (2, ∞), and decreasing on (-2, 2). The concavity of the curve changes at x = -2 and x = 2, and there are points of inflection at these values. A sketch of the graph can show the shape and behavior of the function.

(a) To find the domain of the function, we need to identify any values of x that would make the function undefined. In this case, the function is defined for all real numbers except when the denominator is equal to zero. Thus, the domain is (-∞, -2) ∪ (-2, 2) ∪ (2, ∞) in interval notation.

(b) Vertical asymptotes occur when the function approaches infinity or negative infinity as x approaches a certain value. In this case, there are no vertical asymptotes because the function is defined for all real numbers. The horizontal asymptote can be found by taking the limit as x approaches infinity or negative infinity. As x approaches infinity, the function approaches 0, so y = 0 is the horizontal asymptote.

(c) To find the critical points of f, we need to solve for x when the derivative f'(x) equals zero. In this case, the derivative is -x²-4. Setting it equal to zero, we have -x²-4 = 0. Solving this equation, we find x = -2 and x = 2 as the critical points. The function behaves differently on each side of these points. On the intervals (-∞, -2) and (2, ∞), the function is increasing, while on the interval (-2, 2), the function is decreasing.

(d) The curve is increasing on the intervals (-∞, -2) and (2, ∞), which can be represented in interval notation as (-∞, -2) ∪ (2, ∞). It is decreasing on the interval (-2, 2), represented as (-2, 2).

(e) The concavity of the curve changes at the critical points x = -2 and x = 2. To find the points of inflection, we can solve for x when the second derivative f''(x) equals zero. However, the given second derivative f'(x) = -x²-4 is a constant, and its value is not equal to zero. Therefore, there are no points of inflection.

(f) A sketch of the graph can visually represent the shape and behavior of the function, showing the critical points, increasing and decreasing intervals, and the horizontal asymptote at y = 0.

The derivative of the function F(y) = ∫(1+2y)/(t*sin t) dt / (1-2) is (1+2y) × (-cosec t) / t.

To find the derivative of the function F(y) = ∫(1+2y)/(t*sin t) dt / (1-2), we'll use the Fundamental Theorem of Calculus and the Quotient Rule.

First, rewrite the integral as a function of t.

F(y) = ∫(1+2y)/(t × sin t) dt / (1-2)

      = ∫(1+2y) × cosec t dt / (t × (1-2))

Then, simplify the expression inside the integral.

F(y) = ∫(1+2y) × cosec t dt / (-t)

     = ∫(1+2y) × (-cosec t) dt / t

Then, differentiate the integral expression.

F'(y) = d/dy [∫(1+2y) × (-cosec t) dt / t]

Then, apply the Fundamental Theorem of Calculus.

F'(y) = (1+2y) × (-cosec t) / t

The value of total cell count after 5 hours is given by 11 + ∫[0,5] r(t) dt.

To find the total cell count after 5 hours, we need to integrate the growth rate function r(t) over the interval [0, 5] and add it to the initial cell count.

Let's assume the growth rate function r(t) is given in thousand cells per hour.

The total cell count after 5 hours can be calculated using the integral:

Total cell count = Initial cell count + ∫[0,5] r(t) dt

Given that the initial cell count is 11 thousand cells, we have:

Total cell count = 11 + ∫[0,5] r(t) dt

Integrating the growth rate function r(t) over the interval [0,5] will give us the additional number of cells that have been grown during that time.

The result will depend on the specific form of the growth rate function r(t). Once you provide the function or the equation describing the growth rate, we can proceed with evaluating the integral and obtaining the total cell count after 5 hours accurate to at least 2 decimal places.

Finding the sum of an infinite geometric series involves calculating the limit of the partial sums, while finding the nth partial sum involves adding up a finite number of terms.

An infinite geometric series is a series where each term is multiplied by a common ratio. The formula for the sum of an infinite geometric series is S = a / (1-r), where a is the first term and r is the common ratio. However, to find the sum, we need to calculate the limit of the partial sums, which involves adding up an increasing number of terms until we reach infinity.

On the other hand, finding the nth partial sum of a geometric series involves adding up a finite number of terms up to the nth term. The formula for the nth partial sum is Sn = a(1-r^n) / (1-r), where a is the first term, r is the common ratio, and n is the number of terms.

While both involve adding up terms in a geometric series, finding the sum of an infinite geometric series and finding the nth partial sum are different processes that require different formulas.

b. The solution to the equation 4[r] + [-x - 8] = 0 is x = 4r - 8.

a. To solve the equation x - 3| + 2x = 6, we need to consider two cases based on the absolute value term:

Case 1: x - 3 ≥ 0

In this case, the absolute value term |x - 3| simplifies to x - 3, and the equation becomes:

x - 3 + 2x = 6

Combining like terms:

3x - 3 = 6

Adding 3 to both sides:

3x = 9

Dividing both sides by 3:

x = 3

So, x = 3 is a solution in this case.

Case 2: x - 3 < 0

In this case, the absolute value term |x - 3| simplifies to -(x - 3), and the equation becomes:

x - 3 - 2x = 6

Combining like terms:

-x - 3 = 6

Adding 3 to both sides:

-x = 9

Multiplying both sides by -1 (to isolate x):

x = -9

So, x = -9 is a solution in this case.

Therefore, the equation x - 3| + 2x = 6 has two solutions: x = 3 and x = -9.

b. To solve the equation 4[r] + [-x - 8] = 0, we can simplify the expression inside the absolute value brackets first:

4r + (-x - 8) = 0

Next, distribute the negative sign:

4r - x - 8 = 0

To isolate x, we can rearrange the equation:

-x = -4r + 8

Multiply both sides by -1 (to isolate x):

x = 4r - 8

Therefore, the solution to the equation 4[r] + [-x - 8] = 0 is x = 4r - 8.
