Answer:

z = 1/2

Step-by-step explanation:

Step 1: Write equation

-3z - 1 = 1 - 7z

Step 2: Solve for x

Add 7z to both sides: 4z - 1 = 1
Add 1 to both sides: 4z = 2
Divide both sides 4: z = 1/2

Step 3: Check

Plug in z to verify it's a solution.

-3(1/2) - 1 = 1 - 7(1/2)

-3/2 - 1 = 1 - 7/2

-5/2 = -5/2

Answer:

g(1) = -6

Step-by-step explanation:

g(x) = -2x^2 - 4x

You want to solve for g(1). To do this make every x value in the original equation become 1.

g(1) = -2(1)^2 - 4(1)

Evaluate the exponent.

g(1) = -2(1) - 4(1)

Multiply.

g(1) = -2 - 4

Subtract.

g(1) = -6
