Please help math problem two questions!!! Will fan and medal for quickest and correct answer! :)
Is the relationship between the variables in the table a direct variation, an inverse variation, or neither? If it is a direct or inverse variation, write a function to model it.
x 2 5 20 40
y 40 20 5 2
A. neither
B. inverse variation; y = 20/x
C. direct variation; y = 20x
D. direct variation; y = x+15

Best ResponseYou've already chosen the best response.1as x gets bigger, then y gets smaller right?

Best ResponseYou've already chosen the best response.1lets check if it is \[y=20x\] is \[20=10\times 5\]?

Best ResponseYou've already chosen the best response.1\[y=x+15\] is not direct variation so we can forget that one too

Best ResponseYou've already chosen the best response.0so it's either a or b?

Best ResponseYou've already chosen the best response.1and \[y=\frac{20}{x}\]means if you divide \(20\) by \(x\) you should get \(y\)

Best ResponseYou've already chosen the best response.1if \(x=20\) then \(y=5\) from the table is \[5=\frac{20}{20}\]?

Best ResponseYou've already chosen the best response.020/20 is 1 so would it be b?

Best ResponseYou've already chosen the best response.1no not B since as you said \(\frac{20}{20}=1\) not \(5\)

Best ResponseYou've already chosen the best response.0can you help me with the second one too if i'm not too much of a pain?

Best ResponseYou've already chosen the best response.1gotta do it quick \[y=\frac{k}{x}\] or \[xy=k\] you have \(y=30,x=44\) so \[k=30\times 44=1320\]

Best ResponseYou've already chosen the best response.1put \(x=55\) and compute \[y=\frac{1320}{55}\] to get your answer good luckn !
