Solving inequalities
posted by Joanie .
I have to solve the following inequalities:
x^2 + y^2 is less than or equal to 49
y is less than or equal to 3x^2
I know that these are the equations of a circle and a parable. There should be 3 solutions. However, I am not sure how to solve these equations. CAn you help? Thanks.

solve them equal, then...for instance...
x^2+y^2<=7^2 which means the radius of all points x,y from the origin is less or equal to 7...which does indeed mean the circle and all points in it. 
5x+10>20

10 ¡Ü 2 + 4x < 20
