## hugsandkisses Group Title If y varies inversely as x, find the constant of variation if y = 14 when x = 8. A. 112 B. 2 C. 7/4 D. 7 2 years ago 2 years ago

y=k/x

2. Mertsj Group Title

Plug in the given y and x values and find k which is the constant of variation.

3. hugsandkisses Group Title

I don't get it

4. Mertsj Group Title

Did you see the equation I wrote?

5. hugsandkisses Group Title

yes I did so it would be 14=k/8

6. Mertsj Group Title

$y=\frac{k}{x}$

7. Mertsj Group Title

Now solve that for k by multiplying both sides by 8

8. Mertsj Group Title

$14(8)=\frac{k}{8}(8)$

9. hugsandkisses Group Title

112=k/64?

10. Mertsj Group Title

11. hugsandkisses Group Title

Ohh, I see! Thanks for taking the time to explain that!

12. Mertsj Group Title

That's why you multiply both sides by 8...so that the 8"s on the right will cancel.

13. hugsandkisses Group Title

I see, Thanks so much!
