Question

Y varies inversely with x y = 132 when x = 6 What is the value of k, the constant of inverse variation?

Answer 1

The answer to this question is i think a or b.

Answer 2

$\bf \qquad \qquad \textit{inverse proportional variation} \\\\ \textit{\underline{y} varies inversely with \underline{x}}\qquad \qquad y=\cfrac{k}{x}\impliedby \begin{array}{llll} k=constant\ of\\ \qquad variation \end{array}\\\\ -------------------------------\\\\ \textit{we also know that } \begin{cases} y=132\\ x=6 \end{cases}\implies 132=\cfrac{k}{6}\implies 792=k$
