Answer:

Step-by-step explanation:

First you should write out the entire word equation into one you may recongnize:

7x - 12 = -3x - 32

After this, solve for x:

7x + 3x = 12 - 32

<u>10x</u> = <u>-20</u>

10      10

x = -2

Find the x and y intercept for -2x-5y=30
Ahat [919]

Answer:

see below

Step-by-step explanation:

-2x-5y=30

To find the x intercept, set y =0 and solve for x

-2x-5*0=30

-2x = 30

Divide each side by -2

-2x/-2 = 30/-2

x =-15

To find the y intercept, set x =0 and solve for y

-2*0-5y=30

-5y = 30

Divide each side by -5

-5y/-5 = 30/-5

y = -6

20 points<br> How on Earth am I supposed to do this
goblinko [34]

Answer: -89

Step-by-step explanation:

So your equation is

- 9(a) - 7(x) - 9(c) - 9(b) - 7(y)

You know that (a) (b) and (c) = -1

You also know that (x) and (y) = 7

So, when you put this into the equation, it will look like this:

- 9(-1) - 7(7) - 9(-1) - 9(-1) - 7(7)

When you work that out you will get left with your answer, which is -89.

harkovskaia [24]
When you evaluate the equation you plug in the numbers or replace the variables with the numbers it’s giving you.
-8(2)(-32) - 2(-8) + 4
-16(-32) - 16 + 4
512 + 20
= 532
