Solution
Your input: find the constant of variation k given z=kx2y, z=7 when x=5 and y=3 and find y when z=12 and x=1.
We have that z=kx2y.
Plug in the given values to find k: 7=k⋅5231.
Solving this equation, we obtain that k=2125.
Now find y.
Plug in the given values and found k to find y: 12=2112y125.
From this equation, we have that y=7100.
Answer: the constant of variation is k=2125, y=7100.
