Answer: This should be under the subject English or Art, not math.
Step-by-step explanation: Go motivation, if a little rude.
So your equation is a composite function. It means to plug 1.5 as x into g(x), then the answer you get for that, plug into h(x).
So.
g(1.5)=8-3(1.5)
=8-4.5
=3.5
Then.
H(3.5)=2x+5
=2(3.5)+5
=7+5=12
Your final answer is 12.
Answer: Your answer is d because if you solve for x you will get 180 and if you plug 180 into the equation it equals 700.
