HI!!
Nerdgirl
  • Nerdgirl
hi can someone help me?
misty1212
  • misty1212
which one are you doing?
Nerdgirl
  • Nerdgirl
both. preferably the first one first then the second one @misty1212
misty1212
  • misty1212
as x gets bigger, then y gets smaller right?
Nerdgirl
  • Nerdgirl
yep
misty1212
  • misty1212
lets check if it is \[y=20x\] is \[20=10\times 5\]?
Nerdgirl
  • Nerdgirl
er....... sorry my brain is kind of fried normally i'd be able to do this quickly
misty1212
  • misty1212
take your time,\(10\times 5\) is not that hard to do
Nerdgirl
  • Nerdgirl
oh! right! sorry. hehe. dumb moment. 50
misty1212
  • misty1212
ok so we can forget that one
misty1212
  • misty1212
\[y=x+15\] is not direct variation so we can forget that one too
Nerdgirl
  • Nerdgirl
so it's either a or b?
misty1212
  • misty1212
and \[y=\frac{20}{x}\]means if you divide \(20\) by \(x\) you should get \(y\)
misty1212
  • misty1212
if \(x=20\) then \(y=5\) from the table is \[5=\frac{20}{20}\]?
Nerdgirl
  • Nerdgirl
20/20 is 1 so would it be b?
misty1212
  • misty1212
?
misty1212
  • misty1212
no not B since as you said \(\frac{20}{20}=1\) not \(5\)
Nerdgirl
  • Nerdgirl
oh right! sorry. ugh....... I hate math. thanks again.
misty1212
  • misty1212

Nerdgirl
  • Nerdgirl
can you help me with the second one too if i'm not too much of a pain?
misty1212
  • misty1212
gotta do it quick \[y=\frac{k}{x}\] or \[xy=k\] you have \(y=30,x=44\) so \[k=30\times 44=1320\]
misty1212
  • misty1212
put \(x=55\) and compute \[y=\frac{1320}{55}\] to get your answer good luckn !
