Answer:

x= -14

Step-by-step explanation:

Use the distributive property to simplify.

4x+2(4) = 3x-2(3)

Now, multiply.

4x+8 = 3x-6

Move the variable to one side, you do that by subtracting the smallest variable to both sides.

4x+8 = 3x-6

-3x -3x

Subtract 8 to both sides.

x+8= -6

-8 -8

x= -14

egoroff_w [7]

Answer:

$f(-1) = -12$

Step-by-step explanation:

<u>Step 1: Set x to -1 and solve</u>

<u /> $f(x) = -3x^2+2x-7$

$f(-1) = -3(-1)^2+2(-1) - 7$

$f(-1) = -3(1) - 2 - 7$

$f(-1) = -3 - 2 - 7$

$f(-1) = -12$

Answer: $f(-1) = -12$
