Best ResponseYou've already chosen the best response.1Because it varies inversely so it's, xy=k, we just substitute the values that are given in the equation to find k: xy=k 48(4)=k 192=k xy=k 3(y)=192 y=64

Best ResponseYou've already chosen the best response.1And you can also use this way: x1*y1=x2*y2 (i think it's easier)

Best ResponseYou've already chosen the best response.1O.o Okay I'll do it but using the second way. x1*y1=x2*y2 10(20)=25(y) 200=25y y=8
