OpenStudy (alivejeremy):

5*

OpenStudy (texaschic101):

its just a matter of subbing in ur points and seeing which is true

OpenStudy (alivejeremy):

3 Multiply both sides by −1 −y+5<x2

OpenStudy (james1107):

so would it be a @texaschic101

OpenStudy (dayakar):

(x,y) = (2,4) y > -x^2 +5 4 > - (2)^2 +5 4> -4+5 4>1 (true)

OpenStudy (alivejeremy):

4 Regroup terms 5−y<x2

OpenStudy (alivejeremy):

5.Take the square root of both sides ±5−y−−−−√<x

OpenStudy (texaschic101):

not a
