What is the result of adding these two equations?
2x + 3y = -5
5x – y = -12

If the measure of angle 1 is 110 degrees and the measure of angle 3 is (2 x+10 degree), what is the value of x?

The graph of y x3 is translated so that the point (1. 1) is moved to (1, 4). what is the equation of the new graph?
