Answer:
(f/g)(5) = 22
Step-by-step explanation:
All we need to do is plug in 5 for x in both f(x) and g(x) then divide the result of f(x) and g(x) to find our final answer.
Step 1: Plug in 5 for x
f(x) = 7(5) + 4(5) = 55
g(x) = 1/2(5) = 2.5
Step 2: Divide f(x) by g(x)
f(5)/g(5) = 55/2.5 = 22
And we have our final answer!
90 x 0.4 = 36
90 - 36 = 54

<u>Answer</u>:
c = 9
<u>Explanation</u>:
given: f(x)=3x-7
<em>if f(c) =20</em>
To solve this replace x with c and then y is 20.
<u>Solve</u>:
3c - 7 = 20
3c = 27
c = 27 ÷ 3
c = 9
