this is same as previous problem , eliminate 2 options by substituting the x,y values given and tell me which 2 options u get
OpenStudy (howard-wolowitz):
ok i got D and i subed them in like u said.. but I think it might be C do to the fact that I got a decimal
OpenStudy (epoweritheta):
hmm..okay
OpenStudy (howard-wolowitz):
Did you get the same as me W) D.. cause that would mean I'm correct!
OpenStudy (epoweritheta):
i didnt solve it , i let u .... solve it .... see invere means x=k/y or x*y=k
some equations there are not inversely proportional
