Math Problem Statement
Solution
The problem you provided asks to solve the inequality and choose the correct answer from the given options.
Let's solve the inequality step by step:
-
Start with the absolute value inequality:
-
Rewrite as a compound inequality (because of the absolute value):
-
Solve the compound inequality:
- First, subtract 3 from all parts of the inequality:
- Next, divide by and reverse the inequality signs (since we are dividing by a negative number):
- This simplifies to:
The solution is that is between and , which corresponds to option C: .
Would you like more details on the solution, or do you have any specific questions? Here are 5 related questions to explore further:
- How do you solve absolute value inequalities in general?
- Why do we reverse the inequality sign when dividing by a negative number?
- How would the solution change if the inequality were ?
- What is the difference between "and" and "or" solutions in compound inequalities?
- How do we graph the solution on a number line?
Tip: When solving inequalities with absolute values, always break them into two cases (positive and negative) before solving.
