Question

Y is inversely proportional to x and y = 24 when x = 2.

what is the constant of proportionality k(k=?)

use y=k/x to find y when x=6.

Answer 1

k = 48

For x = 6, y = 8.

Explanation:

The general equation for inverse variation is

y = k/x

We are told that y = 24 when x = 2, so we plug in those two values in the general equation to find the value of k.

24 = k/2

k = 24 * 2 = 48

Now that we know k = 48, the equation for our case is

y = 48/x

Now we plug in x = 6 and find y.

y = 48/x

y = 48/6

y = 8
