Question

If y varies inversely as x, find the constant of variation if y = 50 and x = 4

Answer 1

how do you turn that into an equation y varies inversely as x

Answer 2

Hint: xy = k

Answer 3

idk?

Answer 4

So basically you're saying it is difficult for you to simply substitute the values of x and y into the equation xy = k and solve for k, right?

Answer 5

yes

Answer 6

Explain to me how it is difficult for you. If you substitute the given values for x and y you get

5*40 = k

Answer 7

Where's the difficulty there?

Answer 8

Now all you have to do is multiply 5 times 40. Can you do that?
