Question

if x =5y , then x and y vary _____ with each other​

Answer 1

$If \:x= 5y \:then \:x\:and \: y \:vary \\</p><p>\underline { \pink { directly } } \:with \:each \:other.$

Explanation:

$Given \:x = 5y$

$\implies \frac{x}{y} = 5$

$\implies \frac{x}{y} = \blue {Constant}$

$\implies x \propto y$

$\underline {\blue { Direct \: Proportion:}}$

if x and y are any two quantities such that both of them increase or decrease together and

$\frac{x}{y}$ remains constant ,then we say that x and y are in direct proportion.

$This \:can\:be \: written \:as \:x \propto y \\and \:read \:as \: x \:is \: directly \: proportional \:to \:y.$
