Question 382793: Graph this system of inequalities
{9x^2+25y^2<=225
{x^2+4y^2>=16 Answer by Fombitz(32388) (Show Source): You can put this solution on YOUR website! If you graph , you get an ellipse.
.
.
.
.
When you pick a point (0,0) and test the inequality.
The solution region is the area inside of the ellipse.
.
.
Similarly if you graph , you also get an ellipse.
.
.
When you pick a point (0,0) and test the inequality.
The solution region is the area outside of the ellipse.
.
.
.
.
So for the system of equations the solution region would be the area between the two ellipses, outside the smaller one and inside the larger one.
