Evaluate the following when x = -2 and y = 3
1) y – x + (3+ x2)
Solve the following equations:
5) When multiplying or dividing by a _________________ number, we SWITCH the inequality sign!
Let’s see what you remember!
2) x – 6 = -20
3) x – 2 = -16
4) x = 10
Solve AND graph the following inequalities (SWITCH SIGN when needed):
6) x + 3 > -7
7) x ≥ 20
8) < 𝑥 2
