Answer:
- commutative
- not commutative
Step-by-step explanation:
1. The functions in a composition will be commutative if they are inverses of each other.
f(g(x)) = 1/4(4x-20) +5 = x -5 +5 = x
g(f(x)) = 4(1/4x +5) -20 = x +20 -20 = x
The functions f and g are inverses of each other and are commutative. Application of these functions in either order will give the same result--the original function's argument.

2. f(g(x)) = 2(x^2 -3) +4 = 2x^2 -2
g(f(x)) = (2x +4)^2 -3 = 4x^2 +16x +13
f(g(x)) gives a different result than g(f(x)), so the functions are not commutative.

Answer:
A
Step-by-step explanation:
This graph represents the inequality x < 2. you may be confused as to why the answer is not x ≤ 2, but the circle at the start of the line is not shaded in. This tells us that an answer to this inequality cannot be x
Answer:
x = 50
Step-by-step explanation:
x/5 = 10
Multiply both sides of the equation by 5.
5(x/5) = 5(10)
x = 5(10)
x = 50
The value of x is 50.
