Is this an open or closed interval?
Reasoning: Explain why the absolute value equation |3x| + 8 = 5 has no solution.
Compare and Contrast: Explain the similarities and differences in solving the equation |x - 1| = 2 with solving the inequalities |x - 1| ≤ 2 and |x - 1| ≥ 2.
Compare these two inequalities. (How are they alike?)
Contrast these two inequalities. (How are they different?)
