Yvaries inversely as x, and y = 50 when x = 10. what is the value of y when x = 20? 100 25 10

Step-by-step explanation:

We have been given that y varies inversely as x and , when .

We know that when y varies inversely with x, then the equation is: , where, k represents constant of variation.

First of all, we will find constant of variation using point , and as shown below:

Upon substituting in inversely proportion we will get:

To find the value of y, we will substitute in above equation as:

Therefore, the value of y is 25.

but which class are u may know that first

the answer is 11.2 (i know i’m late)
