Math Problem Statement
Solve the inequality |3 - 2x| > 11 and graph the solution set.
Solution
To solve the inequality , we need to break it down into two separate cases, since the absolute value inequality can be expressed as:
Let's solve each case individually:
Case 1:
- Subtract 3 from both sides:
- Divide by -2 (remember to flip the inequality sign when dividing by a negative number):
Case 2:
- Subtract 3 from both sides:
- Divide by -2 (again, flip the inequality sign):
Solution Set
The combined solution is or . In interval notation, this is:
Thus, the correct answer is option A, with the solution set being .
