2. If x = 3: Then what is 9x - 18?
3.If x = 8: Then what is -2x + 10?
4. If x = -3: Then what is 5x + 11?

Answer 1

1 = -48

2 = 9

3 = -6

4 = - 4

Explanation:

Hello there!

For each problem we are going to want to plug in the value of x (which is given) and find the total value of the expression

For #1

8(-4) + 4(-4)

8 * - 4 = -32

4*-4=-16

-32+(-16)=-48

So the answer to #1 is -48

For #2

9(3)-18

9*3=27

27-18=9

so the answer to #2 is 9

For #3

-2(8)+10

-2*8=-16

-16+10=-6

so the answer to #3 is -6

For #4

5(-3)+11

5*-3=-15

-15+11=-4

So the answer to #4 is -4
