Medal, Fan, and Testimonial!

suppose that y varies inversely with x, and y = 4 when x=12. What is the equation for the inverse variation?

Answer 1

This is for a study guide, not for a test or lesson or anything like that. I need to know how to do it, not just the answer.

Answer 2

I have a few more also. Please help! :)

Answer 3

Inverse Variation Formula: y = k / x
Substitute for x and for y: = k /
Solve for k: = k New equation: y = / x
Substitute for x: y = /
Answer: y =

Answer 4

can you get it that way? or do you want the answer?

Answer 5

Okay, so it would be 4 = k/12

Answer 6

correct

Answer 7

Then it would be k = 48

Answer 8

right

Answer 9

48/12 would be 4. So 4?
