using a number line, find both the intersection and the union of the following interval: (-∞, 7) and [-5, +∞)

Answer:

5924, 51

Step-by-step explanation:

X = 4200(1.035)^10

And put it in a calculator

The total value of the account after 10 years is $5,924.52.

Given that,

Based on the above information, the calculation is as follows:

[tex]= \$4,200 \times (1 + 3.5\%)^{10}[/tex]

= $5,924.52

Therefore we can conclude that the total value of the account after 10 years is $5,924.52.

Answer:

-16 Degrees

Step-by-step explanation:

Just subtract: 2-18=negative 16 --> -16

Answer:

angle (3x-15)°=angle (2x+10)° (by vertically opposite angles)

3x-15=2x+10

3x-2x=10+15

x=25

by putting the value of x.

3x-15=3×25-15 = 60°

38°+ 60°+ <ebf= 180° (by sum of all sides is 180° )

98°+<ebf = 180°

<ebf = 180° - 98°

<ebf = 82°

Answer:

son: 12 daniel: 32

Step-by-step explanation:

The graph illustrates a linear function, because the graph is a straight line

The equation of the graph is (d) y = x +3

The points on the line are:

[tex](x_1,y_1) = (-3,0)[/tex]

[tex](x_2,y_2) = (0,3)[/tex]

First, we calculate the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Substitute values for x1, x2, y1 and y2

[tex]m = \frac{3-0}{0--3}[/tex]

Simplify

[tex]m = \frac{3}{3}[/tex]

Divide

[tex]m = 1[/tex]

The equation of the line is then calculated using the following formula:

[tex]y = m(x - x_1) + y_1[/tex]

Substitute values for m, x1 and y1

[tex]y = 1(x - -3) + 0[/tex]

Simplify

[tex]y = 1(x +3)[/tex]

Open bracket

[tex]y = x +3[/tex]

Hence, the equation of the graph is (d) y = x +3

Answer:

1. f(–9) = -66 , g( 1 ) = 27  (Please double-check your given options, there must have been a typographical error for Option C for g( 1 ) = 29). g( 1 ) is supposed to be 27.

2. Option A: f(–9) = 25, g(–1) = 21

Step-by-step explanation:

1.Find the value of f(–9) and g(1) if f(x) = 8x + 6 and g(x) = 9x + 20x−2

f(x) = 8x + 6

f(–9) = 8(-9) + 6 = -66

g(x) = 9x + 20x − 2

g( 1 ) = 9( 1 ) + 20( 1 ) − 2 = 27

None of the given choices were correct (unless there's a typo error for Option C — it's supposed to be g( 1 ) = 27 instead of 29?) because the correct answers are: f(–9) = -66 and g( 1 ) = 27

2.  f(–9) and g(–1) if f(x) = –3x – 2 and g(x) = 3x³ – 24x

f(x) = –3x – 2

f(–9) = –3(–9) – 2 = 25

g(x) = 3x³ – 24x

g(–1) = 3(–1)³ – 24(–1) = 21

Therefore, the correct answer is Option A: f(–9) = 25, g(–1) = 21

Explanation:

Factor the given expression

x^2+x^3

x^2*1+x^2*x

x^2(1+x)

x^2(x+1)

We end up with something where the factor x^2 is a perfect square regardless of whatever we replace x with from the set {1,2,3,...,99,100}.

In short, we don't need to worry about the x^2 portion.

--------------------

The only thing of importance is the x+1 factor.

The x+1 must be a perfect square so that the original expression is as well.

Let's say M is some perfect square between 1 and 100. That means M belongs to the set of values

{1, 4, 9, 16, 25, 36, 49, 64, 81, 100}

If we want M+1 to be a perfect square, then we'll need to subtract 1 from each item in that set above to counteract the "plus 1" in "M+1".

Subtract 1 from each item to end up with this modified set

{0, 3, 8, 15, 24, 35, 48, 63, 80, 99}

--------------------

Every item mentioned in that second set will make x^2+x^3 to be a perfect square.

For example, let's pick x = 15

x^2(x+1) = 15^2*(15+1)  

x^2(x+1) = 15^2*16

x^2(x+1) = 15^2*4^2

x^2(x+1) = (15*4)^2

x^2(x+1) = 60^2

This confirms that x^2+x^3 is a perfect square for x = 15. I'll let you check the other values.

There are 10 values in the set {1^2,2^2,...,9^2,10^2} = {1,2,...,81,100}. There are also 10 values in the set {0,3,8, ..., 80, 99} we got earlier. The cardinality hasn't changed. However, we'll kick out 0 because it's not between 1 and 100. So we end up with 9 as our final answer.

--------------------

To summarize, there are 9 values of x that make x^2+x^3 a perfect square, where x is some whole number between 1 and 100 inclusive.

Answer:

y = 2x - 12

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 2 , then

y = 2x + c is the partial equation

To find c substitute (7, 2 ) into the partial equation

2 = 14 + c ⇒ c = 2 - 14 = - 12

y = 2x - 12 ← equation of line
