1. Изобразив схематически графики, выясните, имеет ли решения система уравнений и если имеет, то сколько:

[tex]a) \left \{ {{y= x^{2}+2 } \atop {y=- x^{2} +7} \right. [/tex]

[tex]b) \left \{ {{ x^{2} + y^{2} =9 } \atop {y- x^{2} =2} \right. [/tex]

2. Решите графически систему:

[tex] \left \{ {{y=| x^{2} +6x+5| }, \atop {y-x=5}.} \right. [/tex]
