Question

Y varies directly as z and inversely as x; write the sentence as an equation

Answer 1

Given:

(y) varies directly as (z) and inversely as (x):

`\begin{gathered} y\propto z;y\propto(1)/(x) \\ \\ so,y\propto(z)/(x) \end{gathered}`

so, the equation will be:

`y=(kz)/(x)`

Where: k is the proportionality constant
