Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

For the f(-2):

[tex]f(-2)=8(-2)-4\\f(-2)=-16-4\\f(-2)=-20[/tex]

For the f(x+7):

[tex]f(x+7)=8(x+7)-4\\f(x+7)=8x+56-4\\f(x+7)=8x+52[/tex]

For the f(-x):

[tex]f(-x)=8(-x)-4\\f(-x)=-8x-4[/tex]

That's all

The function f(x) = 8x - 4, At x = -2 is -20, At x = (x+7) is 8x + 52 and at x = -x is -8x -4.

A function can be though of as an output for given input.

According o the given question we have to evaluate the function                f(x) = 8x - 4 at different values of the independent variable.

For f(-2) we'll replace x with -2 in this function

f(-2) = 8(-2) - 4.

f(-2) = -16 - 4.

f(-2) = - 20.

For f(x+7) we'll replace x with (x+7).

f(x+7) = 8(x+7) - 4.

f(x+7) = 8x + 56 - 4.

f(x+7) = 8x + 52.

For f(-x) we'll replace x with -x in this given equation.

f(-x) = 8(-x) - 4.

f(-x) = -8x - 4.

Answer: It is located in quadrant III (3) of the coordinat plain

Step-by-step explanation:

You can use the negative numbers to find their placement. if there are no negative numbers, it’s in quadrant I (1). If there‘s a negative number for the Y-coordinate, then it’s in quadrant II (2). If there are 2 negative numbers, it’s in quadrant III (3). And if there’s a Negative number for the X-coordinate, it’s in quadrant IV (4).

Complete question :

Larry Mitchell invested part of his $32000 advance at 4% annual simple interest and the rest at 9% annual simple interest. If his total yearly interest from both accounts was ​2430, find the amount invested at each rate. The amount invested at is ​$ nothing. The amount invested at is ​$ nothing.

Answer:

Investment at 4% = $9000

Investment at 9% = $23,000

Step-by-step explanation:

Given that :

Total investment = 32000

Let;

amount invested at 4% = a

amount invested at 9% = 32000 - a

Total interest earned = 2430

Simple interest = principal * rate * time

Investment at 4%:

(a * 0.04) + [(32000 - a) * 0.09] = 2430

0.04a + 2880 - 0.09a= 2430

-0.05a + 2880 = 2430

-0.05a = 2430 - 2880

-0.05a = - 450

a = 9000

Hence,

Investment at 4% = $9000

Investment at 9% = $32,000 - $9000 = $23,000

Answer:

The required line's equation is x=-4. Option A.

Step-by-step explanation:

This is more conceptual than a numerical problem.

We have the line y=1/5 and want to find a perpendicular line that passes through (4,-3).

The line y=1/5 is a horizontal line with slope 0. The perpendicular line would have an infinity slope and it would make it impossible to use the regular procedure to find it.

Instead, we realize that a perpendicular line to a horizontal line is a vertical line.

All vertical lines have the equation x = h, where h is the x-component of the point it passes through.

Now we only have to see the x-component of the point (-4,-3) and write our solution:

The required line's equation is x=-4. Option A.

Answer: A. x= -4
