Find the constant of variation k for the inverse variation. Then write an equation for the inverse variation. Y=4.5 when x = 3
Nookie1986 [14]
\bf \qquad \qquad \textit{inverse proportional variation}\\\\&#10;\textit{\underline{y} varies inversely with \underline{x}}\qquad \qquad  y=\cfrac{k}{x}\impliedby &#10;\begin{array}{llll}&#10;k=constant\ of\\&#10;\qquad  variation&#10;\end{array}\\\\&#10;-------------------------------\\\\&#10;\textit{we also know that }&#10;\begin{cases}&#10;y=4.5\\&#10;x=3&#10;\end{cases}\implies 4.5=\cfrac{k}{3}\implies 4.5(3)=k&#10;\\\\\\&#10;13.5=k\qquad therefore\qquad \boxed{y=\cfrac{13.5}{x}}
