Question

For the inverse variation equation xy = k, what is the value of x when y = 4 and k = 7? 3 28

Answer 1

It would be 7/4 or 1.75 if needed to be in decimal format.

Answer 2

The value of x is
`(7)/(4)`.

Explanation:

It is given that the inverse variation equation is

`xy=k` ..... (1)

The value of y is 4 and the value of k is 7.

Substitute y=4 and k=7 in equation (1).

`x* 4=7`

Divide both sides by 4.

`(x* 4)/(4)=(7)/(4)`

`x=(7)/(4)`

Therefore the value of x is
`(7)/(4)`.
