Solve Combined Variation Problems
-w varies directly as a and inversely as the difference between $x$ and $y$.
A) $w = \frac { k a } { x - y }$
B) $w = \frac { a } { k ( x - y ) }$
C) $w = k a ( x - y )$
D) $w = \frac { k } { a ( x - y ) }$

Question

Quizplus · Accepted Answer

The correct formula for combined variation where $w$ varies directly as $a$ and inversely as the difference between $x$ and $y$ is $w = \frac { k a } { x - y }$, where $k$ is the constant of variation.
