Find an equation of variation in which $y$ varies inversely as $x$ and the following is true.
-$y=0.25$, when $x=32$
A) $y=\frac{9}{x}$
B) $y=\frac{8}{x}$
C) $y=8 x$
D) $y=\frac{11}{x}$

Quizplus · Accepted Answer

In an inverse variation, $y = \frac{k}{x}$, where $k$ is the constant of variation. Given $y=0.25$ when $x=32$, we find $k$ by multiplying $y$ and $x$, thus $k = 0.25 \times 32 = 8$. Therefore, the equation of variation is $y = \frac{8}{x}$.
