Question

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

4/7
7/4
3
28

Answer 1

7,4 is the answer to the question

Answer 2

`x=7/4`

Explanation:

the equation is:

`xy=k`

To find the value of
`x`, we need to substitute the values that we know for
`y` and
`k`:

`y=4`

and

`k=7`

so, we substitute this values into the equation

`xy=k`

`x(4)=7`

and we clear for
`x`, for this we move the 4 to the right dividing:

`x=7/4`
