(
for each pair of functions f and g below, find f (g(x)) and g
then, determine whether f and g are inverses of each other.
simplify your answers as much as possible.
(assume that your expressions are defined for all x in the domain of the composition.
you do not have to indicate the domain.)
(a) f(x) = * =
(b) f(x) = 2x
8(x) = 2x + 5
g(x) = 2x
xs ?
f(g(x)) = 0
f($(x)) = 0
8v(x)) = 0
8((x) =
0
f and g are inverses of each other
f and g are not inverses of each other
f and g are inverses of each other
f and g are not inverses of each other

i got 142 as my answer

step-by-step explanation:

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

one set of data has more variation than the other. hope this !
