@JoannaBlackwelder time for ya next medal lol
Haha! Any thoughts on how to start?
yeah start subbing for the first equation to see wich one imakes it a true statement

Hm, no, that's not what is meant by substitution.
ohhh
|dw:1439922974168:dw| First solve for a variable.
ok this is harder then i thought haha
|dw:1439923058436:dw| Then sub it into the other equation.
Yeah, it can be tricky.
x² + (-x-15)² = 113 x² + (-x - 15)(-x - 15) = 113 x² + x² + 30x + 225 = 113 2x² + 30x + 112 = 0 2(x² + 15x + 56) = 0 2(x + 8)(x + 7) = 0 x = -8, -7 would this be right
If x = -8, then -8 + y = -15 So y = -7 So a solution is (-8, -7) If x = -7, then -7 + y = -15 y = -8 So a solution is (-7, -8)
Hm, no, y=15-x, not -15-x
ok so go on with your explaing i thoght i had it atleast i tride un like the folks who just want answers haha
It looks like you have the right idea for the rest of it. You just messed up on defining y. Valiant effort! :-)
ok so can you correct me please
x² + (-x+15)² = 113 See why?
ohh ok make sence
Cool, what do you get from there?
i got x=7
or x=8
Awesome! And what are the corresponding y values?
so (8,7)(7,8)
Great job!
thnx
and thnx for your help once again
You're welcome :-)
