## anonymous one year ago help If y = -7.5 when x = 25, find y when x = 5.

1. Haseeb96

where is the equation?

2. anonymous

that's all it says it don't have one just says solve for X

3. anonymous

Question is still incomplete.. Have you got any Direct or Indirect Variation Case for this question??

4. Haseeb96

there must be some relation between these two variables @wolftears

5. anonymous

Can you take screenshot of your question and attach here?

6. anonymous

Assume that y varies inversely as x.

7. anonymous

That is what I was looking for.. :P

8. anonymous

y varies inversely with x means : when y increases, x decreases and when y decreases x increases..

9. anonymous

You can show this variation as: $y = \frac{k}{x} ; k = constant$

correct @eta |dw:1432752063862:dw|

@Haseeb96 you proceed now.. :)

12. Haseeb96

how do u put the problem in the eqation u show a example

16. Haseeb96

when you will put y=-7.5 and x =25 in the above equation you will get the k

17. Haseeb96

so we get k=-187.5 now put x =5 and k = -187.5 into the above equation and get the y

18. anonymous

srry my labtop is being slow today and I still do same thing

19. Haseeb96

when would you put them you will get y = -37.5

20. Haseeb96

21. Haseeb96

my dear friend @wolftears do you have any questions about it?

22. anonymous

how you exactly get the answer do you x's it or / it

23. Haseeb96

24. Haseeb96

i hope you get it

25. anonymous

Reason why I asked bc I have 1 more problem like this but it says if y=-16 when x=4, Find x when y = 36

26. anonymous

do u still need help?
