Answer:

Y=-3/1x+7

Step-by-step explanation:

-3/1 is the slope, which is negative, and 7 is the y intercept ( the value that is marked at the middle of the y-axis).

Graph the lines: y= 4x, y = – 4, and x = - 2.

Answers

How can we answer this

Attached is a screenshot of the graphed lines.

I graphed the line, y = 4x, by using the y-intercept (0 ,0), and used the slope (m = 4) to plot other points: {(-1, -4), (1, 4)}.

For y = -4, it is a horizontal line (y = b) with a zero slope. Therefore, regardless of the x-value, its corresponding y-coordinate will be the same (y = -4). To graph the line for y = -4, start at y = -4 and create a horizontal line from there.

For x = -2, it is a vertical line (x = a) with an undefined slope. A vertical line has undefined slope because all points the line have the same x-coordinate. Thus, regardless of the y-value, its corresponding x-coordinate will always be x = -2. To graph the graph, I started at point (-2, 0), and created a vertical line from there.

Hello everyone i need ur help to factor out this in a easy way.

Answers

9514 1404 393

Answer:

(x -1/4)(x -1)(x +1)

Step-by-step explanation:

Pairs of coefficients have the same ratio, so it is likely that you can factor this by grouping pairs of terms.

x³ -x -1/4x² +1/4 = (x³ -x) -(1/4x² -1/4) . . . . . . note the signs

= x(x² -1) -1/4(x² -1)

= (x -1/4)(x² -1)

The difference of squares (x² -1) is a special form that has factors (x -1)(x +1)

Your factoring is ...

(x -1/4)(x -1)(x +1)

_____

Additional comment

The difference of squares factors like this:

a² -b² = (a -b)(a +b)

The length of side ST of the triangle SRT using concept of similar triangles is; ST = 22 km

How to find Length of Similar Triangles?

We are given a Triangle PQR.

In Triangle PQR, Side PQ = 16 kilometers and side PR = 24 kilometers.

In Triangle SRT, Side RT = 33 kilometers.

Using concept of ratio of similar triangles, we can say that;

ST/RT = PQ/PR

Thus;

ST = RT * (PQ/PR)

ST = 33 * (16/24)

ST = 22 Km

What is the conditional statement?

A conditional statement is defined as the two fundamental components that make up a conditional statement are Hypothesis (if) and Conclusion (then).

Let us consider the example to understand the parts of a conditional statement.

Conditional Statement: If today is Friday, then yesterday was Thursday.

Hypothesis: "If today is Friday."

In the given problem,

Conditional Statement: If p → q and q are true, then p is true,

Hypothesis: "If p → q and q are true"

Hence, the statement that If p → q and q are true, then p is true which is the correct answer would be option (A)

Find the slope of the tangent line to the given polar curve at the point specified by the value of θ

r = 9 + 8 cos(θ), θ = π/3

Answers

The given curve has equation

r(θ) = 9 + 8 cos(θ)

and its derivative is

dr/dθ = -8 sin(θ)

When θ = π/3, we have r (π/3) = 13, and dr/dθ (π/3) = -4√3.

Differentiate these with respect to θ :

dy/dθ = dr/dθ sin(θ) + r(θ) cos(θ)

dx/dθ = dr/dθ cos(θ) - r(θ) sin(θ)

In polar coordinates, we have

y(θ) = r(θ) sin(θ)

x(θ) = r(θ) cos(θ)

and when θ = π/3, we have y (π/3) = 13√3/2 and x (π/3) = 13/2.

The slope of the tangent line to the curve is dy/dx. By the chain rule,

dy/dx = dy/dθ • dθ/dx = (dy/dθ) / (dx/dθ)

dy/dx = (dr/dθ sin(θ) + r(θ) cos(θ)) / (dr/dθ cos(θ) - r(θ) sin(θ))

When θ = π/3, the slope is

dy/dx = (-4√3 sin(π/3) + 13 cos(π/3)) / (-4√3 cos(π/3) - 13 sin(π/3))

dy/dx = (-4√3 (√3/2) + 13 (1/2)) / (-4√3 (1/2) - 13 (√3/2))

dy/dx = - 1/(17√3)

So, the tangent line has slope -1/(17√3) and passes through (13/2, 13√3/2). Using the point-slope formula, its equation is

y - 13√3/2 = -1/(17√3) (x - 13/2)

y = -(x - 338)/(17√3)
