Question

Y varies inversely with x
k= 1.25
What is the value of y when x is 5?

Answer 1

The value of y is 0.25

Explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form
`y*x=k` or
`y=k/x`

For x=5

Find the value of y

k=1.25

substitute in the equation

`y=k/x` ----->
`y=1.25/5=0.25`
