Question

Suppose that y varies inversely with x, and y = 6 when x = 8. What is an equation for the inverse variation?

Answer 1

Any ideas?

Answer 2

y=x/48?

Answer 3

Sooo... Close!

Answer 4

y=x/48?

Answer 5

48/x i mean

Answer 6

Yup.

y = 48/x

Because the form of an inverse variation is y = k/x.

Answer 7

thanks!

Answer 8

Good job :D

Answer 9

Begin with the definition of an inverse variation:

$$\huge y=\dfrac{k}{x}$$

Answer 10

Or $$\huge xy=k$$
