Answer:
x - 9
Step-by-step explanation:
(f ÷ g)(x) = f(x) ÷ g(x), that is
← factorise the numerator
=
← cancel the common factor (x - 10) on numerator/denominator
= x - 9

Answer:
60 ft.
Step-by-step explanation:
We can solve this problem with a simple proportion:
24 / 10 = h / 25
10h = 24 * 25
600 = 10h
60 ft. = h
Answer:
40 miles
Step-by-step explanation:
let distance be d and time be t
Since d varies directly with t, then the equation relating them is
d = kt ← k is the constant of variation
To find k use the condition d = 75 when t = 3
k =
=
= 25
d = 25t ← equation of variation
when t = 1.6, then
d = 25 × 1.6 = 40 miles
