Simplify (3x^2 + 2x + 1) + (3x - 8) - (x^2 + 6x - 5)

Use the elimination method to solve the system of equations -x+5y=-4 and 4x+3y=16

#1-20 state whether the angles are alternate interior, alternate exterior, vertical, or corresponding angles.

Choose the linear inequality that describes the graph. the gray area represents the shaded region. a: y ≤ –4x – 2 b: y > –4x – 2 c: y ≥ –4x – 2 d: y < 4x – 2
