Find an equation of variation in which the following are true.
-$y$ varies jointly as $x$ and $w$ and inversely as $z$, and $y = \frac { 9 } { 2 }$ when $x = 2 , w = 6$, and $z = 24$.
A) $y = \frac { 6 z } { x w }$
B) $y = 4 x w z$
C) $y = \frac { 6 x w } { z ^ { 2 } }$
D) $y = \frac { 9 x w } { z }$

Question

Quizplus · Accepted Answer

The correct equation of variation is $y = \frac { 9 x w } { z }$ because it represents $y$ varying jointly as $x$ and $w$ (indicated by $xw$ in the numerator) and inversely as $z$ (indicated by $z$ in the denominator). The constants and variables are correctly aligned to satisfy the given conditions.
