The value of y varies inversely as √x and when x=25, y=15. What is x when y=3?
+208 \(\sqrt{x}*y=k\)
\(5*15=k\)
\(k=75\)
\(\sqrt{x}=\frac{75}{3}\)
\(x=625\)

+37146 y = k / (sqrtx) sub in the values to calculate the proportionality constant 'k'
15 = k/(sqrt25)
k =75
3 = 75/(sqrtx)
75/3 = sqrt x
625 = x
