Best ResponseYou've already chosen the best response.0well y varies inversely with x means for constant k we have: \[y=\frac{k}{x}\] first step is to plug in (2,8) to find k

Best ResponseYou've already chosen the best response.0then after you find k you can find x for when y is 3

Best ResponseYou've already chosen the best response.0by pluggin (2,8) as suggested above

Best ResponseYou've already chosen the best response.0(2,8) tells us when x=2 that y=8

Best ResponseYou've already chosen the best response.0and as you see 16/2=8 is true yes k=16

Best ResponseYou've already chosen the best response.0now the question is to find x for when y=3

freckles

Best ResponseYou've already chosen the best response.0have you found x for when y=3 yet?

freckles

Best ResponseYou've already chosen the best response.0well that is what the question ask you to do

Best ResponseYou've already chosen the best response.0it says to find x in the given ordered pair (x,3)

Best ResponseYou've already chosen the best response.0(x,3) says what is x for when y=3

Best ResponseYou've already chosen the best response.0you already found the equation above

freckles

Best ResponseYou've already chosen the best response.0you just need to input the y is 3

Best ResponseYou've already chosen the best response.0do you remember you found k was 16 so I replaced the k with 16 got you \[y=\frac{16}{x}\] re[place y with 3 and solve for x

Best ResponseYou've already chosen the best response.0by solving the equation 3=16/x for x

Best ResponseYou've already chosen the best response.0so that would be 5.3?

Best ResponseYou've already chosen the best response.0close in decimal form that would be 5.33333333333333333333 but I think they wanted you to write it in mix fraction form not decimal form

anonymous

Best ResponseYou've already chosen the best response.0what would that be as a mix fraction?

freckles

Best ResponseYou've already chosen the best response.0so you never wrote improper fractions as mix fractions before?

Best ResponseYou've already chosen the best response.016/3 3 goes into 16, 5 times with a remainder of 1 \[\frac{16}{3}=5\frac{1}{3} \]
