Question

If y=36 when x=4, find y when x=11

Answer 1

If we are assuming that this is a direct variation, y would be equal to 99.

Step-by-step explanation:

To find this, we start with the base equation for direct variation.

y = kx

Now we find k by plugging in our original values for x and y.

y = kx

36 = k(4)

9 = k

Now that we have k, we can model the equation.

y = 9x

And we can use the value of 11 in the next equation to find y.

y = 9x

y = 9(11)

y = 99
