    as x gets bigger, then y gets smaller right?

    \[y=x+15\] is not direct variation so we can forget that one too

    so it's either a or b?

    and \[y=\frac{20}{x}\]means if you divide \(20\) by \(x\) you should get \(y\)

    if \(x=20\) then \(y=5\) from the table is \[5=\frac{20}{20}\]?

    20/20 is 1 so would it be b?

    no not B since as you said \(\frac{20}{20}=1\) not \(5\)

    gotta do it quick \[y=\frac{k}{x}\] or \[xy=k\] you have \(y=30,x=44\) so \[k=30\times 44=1320\]

  33. misty1212

    put \(x=55\) and compute \[y=\frac{1320}{55}\] to get your answer good luckn !
