Solving and graphing a compound inequality joined by or

The video tutorial explains how to solve and graph a compound inequality using 'or'. It begins with an introduction to the concept, followed by solving each part of the inequality separately. The tutorial then demonstrates how to graph the solutions on a number line, highlighting the importance of not including boundary points when the inequality is strict. The video concludes with a summary of the process.

What is the basic idea behind solving a compound inequality?

• Solving only the part with the greater value

• Ignoring one part of the inequality

• Solving each part separately and combining the solutions

• Solving both parts together as a single equation

When solving the inequality X > 2, what operation is performed?

• Dividing both sides by 15

• Multiplying both sides by 15

• Subtracting 15 from both sides

• Adding 15 to both sides

What is the result of solving the inequality X < -2?

• X is greater than -2

• X is not equal to -2

• X is less than -2

• X is equal to -2

How should the points at X = 2 and X = -2 be treated on the graph?

• Only X = 2 should be shaded

• Only X = -2 should be shaded

• They should be included and shaded

• They should be excluded and not shaded

Which direction should be shaded for the inequality X > 2?

• To the left of 2

• Neither side of 2

• To the right of 2

• Both sides of 2
