Math Problem Statement
Solution
The given inequality is . Let's solve this step-by-step:
Step 1: Break the absolute value inequality
For an inequality of the form , where , the solution is split into two cases:
So, we break the inequality into two cases:
Step 2: Solve each inequality
Case 1:
Subtract 5 from both sides: Divide by (and reverse the inequality sign):
Case 2:
Subtract 5 from both sides: Divide by (and reverse the inequality sign):
Step 3: Combine the solutions
The combined solution from both cases is:
In interval notation, this is:
Step 4: Match with the options
From the provided options in the image, the correct one is:
This corresponds to the second option in the list.
Would you like more details on any part of the solution? Here are five related questions to practice:
- How do you solve absolute value inequalities of the form ?
- What happens if in an absolute value inequality ?
- Can you graph the solution of on a number line?
- How do you solve compound inequalities involving "and" or "or"?
- What is the general rule for reversing inequality signs when multiplying or dividing by a negative number?
Tip: Always remember to reverse the inequality sign when dividing or multiplying both sides of an inequality by a negative number.
