Math Problem Statement
Solve
Solve the inequality. Graph the solution set. -4|2x - 3| ≥ -20
Solution
The inequality in the image is:
Step-by-step solution:
- Divide both sides by -4 (remember that dividing an inequality by a negative number flips the inequality sign):
- Solve the absolute value inequality:
This inequality can be rewritten as:
- Solve for by adding 3 to all parts:
- Divide by 2:
Final solution:
The solution set is .
The correct answer would be option B, and the solution in interval notation is:

- What changes in the solution if the inequality sign had been strict (i.e., instead of )?
- How do you graph the solution set on a number line?
- How does dividing or multiplying by a negative number affect inequality signs?
- Can absolute value inequalities have no solutions? If so, under what conditions?
Tip: When solving inequalities, always remember to flip the inequality sign when multiplying or dividing by a negative number!
