Find an equation of variation in which y varies inversely as x and the following is true.
-$y = 30$, when $x = 2$
A) $y = \frac { 32 } { x }$
B) $y = \frac { 15 } { x }$
C) $y = 15 x$
D) $y = \frac { 60 } { x }$

Quizplus · Accepted Answer

In inverse variation, $y = \frac{k}{x}$. Given $y = 30$ when $x = 2$, we find $k$ by $30 = \frac{k}{2}$, so $k = 60$. Thus, the equation is $y = \frac{60}{x}$.
