Answer:
45
Step-by-step explanation:
In an inverse variation situation, we have mathematical relationship between two variables which can be expressed by an equation in which the product of two variables is equal to a constant.
So in this case: x*y is a constant
since x=9 and y=5 so
xy = 45
the constant of variation is 45
For inverse function, we usually write it as [tex]y = \dfrac{45}{x}[/tex]
