Please help, I've never gotten these and I still dont. this test is 95% of my grade

a. 6

b.-10

c. -4

d. 22

e. -4

f. -13

Step-by-step explanation:

Hi!

Alright, so when we say g of some number, we mean input that number instead of x into the formula.

Our g(x) formula is -2x+12.

g(3) = -2(3) + 12 = -6 +12 = 6

a. 6

Our f(x) formula is 1/2x - 8

We input -4 in for x ---> (1/2) (-4) - 8 --> -2 - 8

b. 10

Our f(x) formula is 1/2x - 8

1/2(8)-8 --> 4-8 --> -4

c. -4

Our g(x) formula is -2x+12.

-2(-5)+12 --> 10+ 12 =22

d. 22

Now, e is a multiple step problem. First, we're going to find g(2) and then input our answer into f.

g(2) = -2(2)+12 = -4+12 = 8

f(8) = 1/2(8) - 8 = 4-8 = -4

e. -4

F is also a multi step problem.

We're first going to find f(6) and then g(10) (this order doesn't generally matter) and then take the sum.

f(6) = 1/2(6) -8 = 3-8 = -5

g(10) = -2(10)+12 = -20 + 12= -8

-5+ -8 =-13

f. -13

idk

step-by-step explanation:

use that smart brain

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
