Question

The variables x and y are inversely proportional, and y = 2 when x = 3. What is the value of y when x = 9?

Answer 1

$If\ x\ and\ y\ are\ inversely\ proportional\ then\ xy\ is\ constans.\\\\9y=2\times 3\\\\9y=6\ \ \ \ \ \ /:9\\\\y=\frac{6}{9}\\\\y=\frac{2}{3}$

Answer 2

Y=k/x
2=k/3
k=6
y=6/x
y=6/9=2/3
