1. Warm-Up #27
1) 2x + 2y= 2 x - y = 3 use substitution 2) Evaluate f x = −x 2 −3x+12;x=2 3) Use f(x) = −4x 2 + x -13 and h(x) 2x + 5; find (f−h)

3. Solving Systems of Linear Inequalities
Change to Slope-Intercept Form, y = mx + b
Determine if it is solid (< or >) or dotted line (< or >) before graphing
Choose a point to test out the solution. Only shade the region that is TRUE.
Suggested points to use: (0, 0) or (1, 1)
