Question

Describe the variation 3xy = 5.

A. y varies inversely as the square of x.
B. y varies inversely as x.
C. y varies directly as x.
D. y varies directly as the square of x.

Answer 1

is B.y varies inversely as x.

Answer 2

The answer is the option B

y varies inversely as x.

Explanation:

we know that

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

In this problem we have

`3xy=5` -----> rewrite

`xy=5/3`

The value of k is equal to
`k=(5)/(3)`

therefore

y varies inversely as x.
