Question

If y varies inversely as x and y is 8 when x is 3, how do you find y when x is 2?

Answer 1

`y=12`

Explanation:

`y prop 1/x or y = k*1/x or x*y =k ; y =8 , x=3 :. 8*3 =k` or

`k=24 ; k` is constant of proportionality. The variation

equation is `x*y =24 ; x=2 , y =? :. 2*y =24 or y=12`
