Question

The value of y varies directly with x. When y=334, x=34. What is the value of y when x is 12? a) 4 b) 1/4 c) 2 1/2 d) 4 3/4

Answer 1

The value of y varies directly with x, then the value of y when x is 12 is approximately 117.882.

Step-by-step explanation:

In this question, we are given that the value of y varies directly with x.

This means that as x increases, y will also increase in a proportional manner.

To find the value of y when x is 12, we can use the concept of direct variation.

We know that when y=334, x=34. So, we can set up the equation:

y = kx

Plug in the given values:

334 = k*34

Solve for k:

k = 334/34 = 9.8235

Now, we can use the value of k to find y when x is 12:

y = 9.8235*12 = 117.882

So, the value of y when x is 12 is approximately 117.882.
