Answer:
f(g(-3))= 17.
Step-by-step explanation:
Start evaluating from the inside and work your way out. This means you start with (-3)²=9. Then go and plug that answer in to the equation f(x). f(9)=2(9)-1=17.
Answer:
27.96
Step-by-step explanation:
Answer:
They each carried 25 books each.
Step-by-step explanation:
You get this by doing
84/5=16.8
then you do
84/2/5= 8.4
8.4+16.8=25.2
but round to whatever 5 or higher bump up below 5 keep the same
so your answer results in 25.
Answer:
x = -7 or x = 2/3
Step-by-step explanation:
I'm assuming you meant solve for x when f(x) = 0.
f(x) = 3x(x + 7) - 2(x + 7)
0 = (x + 7)(3x - 2) -- Both terms have a common factor of (x + 7) so we can group them
x + 7 = 0 or 3x - 2 = 0 -- Use ZPP
x = -7 or x = 2/3 -- Solve
