Question

If y varies inversely with x and y=11 when x=3, find the equation that relates x and y.

Answer 1

y =
`(33)/(x)`

Explanation:

Use the inverse relationship equation, y =
`(k)/(x)`

Plug in what we know to solve for k:

11 =
`(k)/(3)`

33 = k

Plug 33 in as k to find the equation:

The equation will be y =
`(33)/(x)`
