Question
For the following exercises, write an equation describing the relationship of the given variables.$y$ varies jointly as $x$ and $z$ and inversely as $w .$ When $x=3, \quad z=5, \quad$ and $w=6,$ then $y=10$.
Step 1
The problem states that $y$ varies jointly as $x$ and $z$, and inversely as $w$. This can be written as $y=k\frac{xz}{w}$, where $k$ is the constant of variation. Show more…
