Solving Linear Absolute Value Equations and Inequalities

What must be true about the right-hand side of an absolute value equation for it to have solutions?

• It must be a fraction.

• It must be an integer.

• It must be zero or positive.

• It must be negative.

When solving the equation |a| = b, what are the two equations you need to solve?

• a = b and a = 0

• a = b and a = -b

• a = b and a = b + 1

• a = b and a = b - 1

If |x - 1| = 4, what are the solutions for x?

• x = 3 or x = -5

• x = 4 or x = -4

• x = 5 or x = -3

• x = 2 or x = -2

How do you solve the inequality |a| < b?

• a > b or a < -b

• a < b or a > -b

• a > b and a < -b

• a < b and a > -b

What is the solution set for the inequality |2x + 3| < 15?

• -9 < 2x + 3 < 9
