Question

Given x varies inversely with y and xy = 2, what is the value of x when y = 1?

Answer 1

x=2

Explanation:

Answer 2

Answer:
`x=2`

Explanation:

The equation for inverse variation is:

`x=(k)/(y)`

Where "k" is the constant of variation.

If you solve for for the constant "k", you get the form:

`k=xy`

So, if
`xy=2` then
`k=2`

Knowing the value of "k", you can find the value of "x" when
`y=1`, by substituting these values into the equation
`x=(k)/(y)`.

Therefore, you get that the value of "x" when
`y=1` is:

`x=(2)/(1)\\\\x=2`
