Solving Absolute Value Equations and Inequalities

The video tutorial covers solving absolute value equations and inequalities from both graphical and algebraic perspectives. It explains how to represent solutions on a number line using compound inequalities and separate inequalities joined by 'or' statements. The tutorial demonstrates graphing techniques to visualize solutions and discusses the algebraic process of solving these equations and inequalities, highlighting the importance of considering both positive and negative scenarios within absolute values.

How do you represent shading between two numbers on a number line?

• With a single inequality

• With a union of intervals

• With a compound inequality

• With a set notation

When solving absolute value equations algebraically, what do you do if the inside is negative?

• Add the negative value

• Ignore the negative value

• Square the negative value

• Do the opposite of the negative value

What is the result when solving an absolute value equation where the inside is positive?

• The absolute value becomes zero

• The absolute value is squared

• The absolute value does nothing

• The absolute value becomes negative

How do you solve an absolute value inequality followed by 'less than'?

• By writing one compound inequality

• By writing two separate inequalities

• By using set notation

What happens to the inequality sign when you divide by a negative number?

• It stays the same

• It becomes positive

• It switches direction

• It becomes zero
