Best ResponseYou've already chosen the best response.0is it going to be y=z4?

Best ResponseYou've already chosen the best response.1you need to isolate y on one side and it will = something in terms of all the other stuff, x

Best ResponseYou've already chosen the best response.1I would multiply both sides of the thing by (z4) first

Best ResponseYou've already chosen the best response.1should that be a +8y instead of the +8z you typed?

Best ResponseYou've already chosen the best response.0its a multiple choice question is my answer right?

Best ResponseYou've already chosen the best response.1ok, just checking, that makes it easier, asking because a y would be a factorable numorator.

Best ResponseYou've already chosen the best response.1multiply both sides by (z4) (z  4)*(z4) = y^2 + 8z  48

Best ResponseYou've already chosen the best response.1expand z^2  8z + 16 = y^2 + 8z  48

Best ResponseYou've already chosen the best response.0\[y=\sqrt{z ^{2}+6z40}\]

Best ResponseYou've already chosen the best response.1move the 8z and the 48 to the other side... z^2  16z + 64 = y^2

Best ResponseYou've already chosen the best response.1take the root of both sides, and you get two answers for y, the + and the  root of all that on the left

Best ResponseYou've already chosen the best response.1\[y = \pm \sqrt{z^216z+64}\]

Best ResponseYou've already chosen the best response.1looking closer, the stuff under the root is a perfect square, factors to (z8)^2 so you get simplified y = z  8 or y = (z8)

Best ResponseYou've already chosen the best response.0so thats the answer? because i said y=z8

Best ResponseYou've already chosen the best response.1yeah if that is the only choice in the multiple choice , there is also the negative of that , and there is a restriction on the values of z, but not sur eif you need that
