A quantity x varies directly with y and inversely with z. Which expression represents the constant of variation,k?

Respuesta :

the answer is xz/y.

Answer:

The expression represents the constant of variation k is  [tex]\frac{xz}{y}[/tex].

Step-by-step explanation:

As given

A quantity x varies directly with y and inversely with z.

[tex]x \propto y[/tex]

and

[tex]x \propto \frac{1}{z}[/tex]

Than combined the above equation.

[tex]x \propto \frac{y}{z}[/tex]

[tex]x = k\frac{y}{z}[/tex]

Where k is the constant of variation.

Than

[tex]k = \frac{xz}{y}[/tex]

Therefore the expression represents the constant of variation k is  [tex]\frac{xz}{y}[/tex].
