The correct Answer is:
To solve the inequality \( |x| < 5 \), we need to interpret what the absolute value means. The absolute value of a number represents its distance from zero on the number line, regardless of direction. Thus, the inequality \( |x| < 5 \) indicates that the distance of \( x \) from zero is less than 5. ### Step-by-Step Solution: 1. **Understanding the Absolute Value Inequality**: The inequality \( |x| < 5 \) can be split into two separate inequalities: \[ -5 < x < 5 \] This means that \( x \) must be greater than \(-5\) and less than \(5\). 2. **Writing the Compound Inequality**: From the above step, we can write the compound inequality: \[ -5 < x < 5 \] 3. **Interpreting the Result**: This tells us that \( x \) can take any value between \(-5\) and \(5\), not including \(-5\) and \(5\) themselves. 4. **Identifying the Correct Option**: Based on the options provided: - Option A: \( x \leq 5 \) - Option B: \( -5 < x < 5 \) (This is correct) - Option C: \( x \leq -5 \) - Option D: \( -5 \leq x \leq 5 \) The correct option that matches our derived inequality is: \[ -5 < x < 5 \] ### Final Answer: The solution to the inequality \( |x| < 5 \) is: \[ -5 < x < 5 \]
