Review y > -6 y > 4 y ≤ -9 1. -2y – 5 < 7 2. 3y – 5 > 7 Write the linear inequality for all real numbers greater than or equal to 4. Write the verbal phrase that describes x ≤ -2. Is the number 4.78 a solution of x < 5? Is the number 6 a solution of x < 6? Solve the inequality 5 – 2x ≥ 3. Then graph it. 1. -2y – 5 < 7 y > -6 2. 3y – 5 > 7 y > 4 3. -2y + 3 ≥ 21 y ≤ -9
