Solving an absolute value inequality

The video tutorial reviews solving absolute value equations and inequalities. It explains how to set up and solve absolute value equations by considering both positive and negative solutions. The tutorial then transitions to solving inequalities, highlighting the importance of flipping the inequality sign when dividing by a negative number. The video concludes with tips on presenting answers in fractional or decimal form, emphasizing the importance of understanding both concepts for exams.

What are the solutions for the equation |3X| = 6?

• X = 1 and X = -1

• X = 6 and X = -6

• X = 3 and X = -3

• X = 2 and X = -2

When solving inequalities, what must you do if you divide by a negative number?

• Flip the inequality sign

• Keep the inequality sign the same

• Add a constant to both sides

• Multiply both sides by a positive number

What is the inequality solution for 5X + 2 > 23?

• X > 21/5

• X < 21/5

• X > 5

• X < 5

What is the inequality solution for 5X + 2 < -23?

• X > -5

• X < -5

• X < -25

• X > -25

Why is it important to express answers in fractional form?

• Fractions are easier to understand

• Fractions are more accurate than decimals

• Fractions are required for EOC or practice reviews

• Fractions are simpler to calculate
