Question

For an inverse variation, y=5 when x=9. The value of the constant of variation is

Answer 1

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 $y = \dfrac{45}{x}$
