F(x)= -2x - 7 and g(x) = -4x + 3 . Find (f • g)(-5)

(f o g)(-5) = -53

Step-by-step explanation:

Step 1: Define

f(x) = -2x - 7

g(x) = -4x + 3

Step 2: Find f(g(x))

f(g(x)) = -2(-4x + 3) - 7

f(g(x)) = 8x - 6 - 7

f(g(x)) = 8x - 13

Step 3: Find (f o g)(-5)

(f o g)(-5) = 8(-5) - 13

(f o g)(-5) = -40 - 13

(f o g)(-5) = -53

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)
