Question

If y varies inversely as x and y=3 when x=4, then y=12 when x=15

Please select the best answer from the choices provided
T
F

Answer 1

F.

Explanation:

y = k/x where k is a constant

given that x = 4 when y = 3, we have:

3 = k/4

So, k =12.

The equation of variation is:

y = 12/x

When x = 15

y = 12/15 = 4/5.

So not 12 so this is False,
