Answer:
Step-by-step explanation:
the combined area = area of the trapezoid + area of the triangle
=
= 6 + 4
= 10
g(4) = 7 and f(g(4)) = 43
First find g:
g(x) = 3x-5
g(x) = 3(4) - 5
g(x) = 12 - 5
g(x) = 7
Plug in:
f(g(4))
f(7)
Now, find f:
7^2 - 7 + 1
49 - 7 + 1
42 + 1
f(x) = 43
y=1/3x-8
let me know if not clear
$1.45-$0.25=x
x=$1.20
