Answer:
<em>X=11</em>
<em>y=22</em>
Step-by-step explanation:
⇒x=11
⇒ y=22
<u>hope it helps....</u>
The inverse is y = (5/y)^2
You can get this by switching the x and y values and then solving for your new y.
x = 5/sqrt(y) ----> Multiply both sides by sqrt(y)
sqrt(y)*x = 5 ---> divide both sides by x
sqrt(y) = 5/x ---> square both sides
y = (5/x)^2
