Solve and graph the solutions.

2 q + 7 –11

Solve:

Then plot its graph.

Solve and graph the solution.

Solve.

4 v + 12 – 8 v – 3 –22

Solve the given inequality and then check your solution. Sketch the solution on a number line.

2.4 x + 3.6 3.9 x – 1.2

If x takes values: –9, –3, 0, 3 and 9, find the values of x that are solutions of:

2 x – 9 8.

If x takes values: –4, –2, 0, 2 and 4, find the values of x that are solutions of:

5 x – 4 21.

The sum of two times a number and 3 lies between –11 and 5.

Solve the compound inequality –11 2 x + 3 5 to find the solutions.

Two consecutive integers can be represented by n and n + 1. State and solve an inequality to represent the sentence: The sum of two consecutive integers is at least 11.

Three consecutive integers can be represented by n , n + 1 and n + 2. State an inequality that represents the sentence: The sum of 3 consecutive integers is more than 21.

Use the given figure. If the area is at least 45 cm ^{ 2 } , describe the value of x .
