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

Answer:

The answer is the option B

y varies inversely as x.

Step-by-step 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 $k=\frac{5}{3}$

therefore

y varies inversely as x.
