So for the first one... Let's just use x for months and m for minutes.
(20m)+(.15m)
20 times the number of months plus .15 times the number of minutes
Same for the next one
(35x)+ (.10m)
35 times the number of months +.10 times the minutes.
Answer:
h(f(x)) = 2x - 11
Step-by-step explanation:
h(f(x)) is a "composite function." We use the function f(x) as the input to the function h(x):
h(x) = 2x + 3, or 2( x ) + 3; replacing x with f(x), or x - 7, we get:
h(f(x)) = 2(x - 7) + 3, or
h(f(x)) = 2x - 14 + 3, or
h(f(x)) = 2x - 11
True, 15k and 3 is the same and greater than
It equals 0.1365853659
you may round as needed
