Best ResponseYou've already chosen the best response.2y^2=36x^2(1) Sub (1) into x^24y^2=64 x^24(36x^2)=64 x^2144+4x^2=64 5x^2=64+144 5x^2=208 x=(+/ sqrt 208/5) and then continue to sub in from here to find the number of solution

Best ResponseYou've already chosen the best response.2@erin512 Im so sorry! There is no solution as y^2=36(+/ sqrt 208/5)^2> y^2=36(208/5) hence there will be no solution as the eqn is undefined

Best ResponseYou've already chosen the best response.0no problem! thank you though :) its a multiple choice question and there options are 1,2,3 or 4 solutions, so i'm not sure which it correct :(

Best ResponseYou've already chosen the best response.0@erin512 @amstro Without solving the equations, there is a maximum _possible_ solution of 4, since they are both second degree. The actual solution is zero, still < maximum possible. The question is very vague. I would put parameters a,b,c,d instead of numbers for the purpose of the question, such as x^2ay^2=64...

Best ResponseYou've already chosen the best response.0@mathmate thank you so much :) so do you think 4 would be the correct answer in this case?
