anonymous · Answer

Please help I really need to get this done!! PLEASE

anonymous · Answer

Nm dont worry about this one... figured it out.. i might ahve a new question shortley

anonymous · Answer

x^2+y^2=21
x^2-y=9

anonymous · Answer

square the second equation,
x^2+y^2+2xy=36.
26+2xy=36
xy=5
x=5/y
y-5/y+6=0
y^2+6y-5=0 .

anonymous · Answer

I woudl be really thankful if you can do that one i ust sent
x^2+y^2=21
x^2-y=9

anonymous · Answer

9+y+y^2=21
y^2+y-12=0;
y=-4,y=3
then find x.

anonymous · Answer

how?? i suck at these

anonymous · Answer

can you tell me x plz?

anonymous · Answer

if y=3,x=sqrt(12)
if y=-4,x=sqrt(5).

All i did was i substitued x^2 from the secnd equation onto the first.

anonymous · Answer

it says there are still more solutions??
