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.
The answer I believe would be "D", the full shape of the triangle should add up to a total of 360 degrees, so adding "123" and "41" comes out to "164" So then you would just see which of the options would add up to 360.
Answer:
50 seconds
Solution: It is given that Clare is paid $90 for 5 hours of work. We know that $1 is equal to 100 cents. Hence, it take 50 seconds to earn 25 cents.
4+n=x
I think this should work but I'm not really sure..
