Question

How do you write inverse variation equation given x = 3, y=7?

Answer 1

`y=21/x`

Explanation:

`"the initial statement is "yprop1/x`

`"to convert to an equation multiply by k the constant of"`
`"variation"`

`rArry=kxx1/x=k/x`

`"to find k use the given condition"`

`x=3,y=7`

`y=k/xrArrk=x xxy=3xx7=21`

`"equation is " color(red)(bar(ul(|color(white)(2/2)color(black)(y=21/x)color(white)(2/2)|)))`
