f(x) = \frac{x-3}{5}
g(x) = 5x+3
g(f(x)) = 5(\frac{x-3}{5})+3 = x-3+3 = x

EDIT:
f(g(x))=\frac{(5x+3)-3}{5}=\frac{5x+0}{5}=\frac{5x}{5}=x

Sovle for x . 4(x-4)=36
Katena32 [7]

Answer:

below

Step-by-step explanation:

x.4 ( x-4) = 36 \\

4x(x-4) = 36 \\

4x^{2} - 16x = 36

add -36 to both sides

4x^{2} - 16x - 36 = 36 -36 \\4x^{2} -16x - 36 = 0

divide both sides by 2

\frac{4x^{2} - 16x - 36  }{4} = 0/4

x^{2} -4x-9 = 0

This is a quadratic equation

let's solve it by  graphing it

The solution are the x-coordinates of the intersection points

The x-coordinates of the intersection points are approximatively -1.6 and 5.6
