QUESTION 3

If y varies inversely as x, find the inverse variation equation for the situation.
y = 1/8 when x = 40

Answer 1

`yx=5`

Step-by-step explanation:

If
`y` varies inversely as
`x` then

`y* x=k` for some constant
`k`

Since
`y = (1)/(8)` when
`x=40`

`\huge \text((1)/(8)\huge \text)*(40)=k`

`\longrightarrow k=5`
