Question

.

Match each expression with its value if x = -3.

1.
21

2.
9

3.
-12

4.
-18


a.
6x

b.
4x

c.
-3x

d.
-7x

Answer 1

For this case we have the variable
`x = -3`:

`A) 6x = 6 (-3) = - 18\\B) 4x = 4 (-3) = - 12\\C) -3x = -3 (-3) = + 9\\D) -7x = -7 (-3) = + 21`

Now, matching each expression with its value we have:

A goes with 4

B goes with 3

C goes with 2

D goes with 1

ANswer:

A goes with 4

B goes with 3

C goes with 2

D goes with 1
