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
