Question

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

12 when x = 15.
Please select the best answer from the choices provided
True
or
False

Answer 1

FALSE

Explanation:

If y varies inversely as x., this is expressed as;

y = k/x

k is the proportionality constant

when y = 3 and x = 4

3 = k/4

k = 3 * 4

k = 12

when x = 15;

y = k/x

y =12/15

y = 4/5

Hence y is not equal to 12 when x = 15.

The correct answer is FALSE
