If f(x) varies directly with x and f(x) = 4 when x = 12, then what is the value of f(x) when x = 60?
ANTONII [103]
ANSWER

f(60)=3\times60=180

EXPLANATION
We were given that
f(x)
varies directly as
x.

We can write this mathematically as,

f(x) \propto \: x.

This implies that,

f(x) = kx
where k is the constant of variation.

f(4)=4k

This implies that,

4k=12

k = 3

The equation becomes

f(x)=3x

When x=60

f(60)=3\times60=180

Ray’s weight increased by 11% in the last two years. If he gained 16.5 pounds, what was his weight two years ago?
xz_007 [3.2K]
11% = 16.5
1% = 16.5 / 11
= 1.5
100% = 1.5 * 100
= 150. His weight two years ago was 150 pounds.
