Best ResponseYou've already chosen the best response.2plug and chug would be the easiest way. the points are given in: (x,y) form, so you can plug them in for the equations, only one set will work on both

Best ResponseYou've already chosen the best response.2For the case of B): (5,2) eqn 1: 2 ≤ 55 2 ≤ 0 < not true, can't be B. For the case of C: (5,2) eqn 1: 2 ≤ 5  5 2 ≤ 10 < not true, can't be C As it happens, this also rules out A and D. the actual roots for this system are: x= 1/2; y =9/2 and x>1/2; x4≤y≤x5

Best ResponseYou've already chosen the best response.0and you made a mistake on the first equation, its suppose to be a negative 2, not positive.

Best ResponseYou've already chosen the best response.0how am I suppose to answer it if all of the answer choices are wrong? this is confusing? lol

Best ResponseYou've already chosen the best response.2indeed i did, 2 ≤ 0 is true, y ≥ x  4 2 ≥ 5 4 2 ≥ 9 is also true, I'm dumb, sorry... B is correct.
