\( |4x+1|\le 13 \) को संख्या रेखा पर दिखाने पर कौन सा अंतराल मिलेगा?
Which interval is obtained when \( |4x+1|\le 13 \) is shown on the number line?
Explanation opens after your attempt
Correct Answer
A. ( [-3,3] )
Concept
\( |4x+1|\le 13 \) gives \( -13\le 4x+1\le 13 \). Thus \( -\frac{7}{2}\le x\le 3 \), not the listed interval.
Why this answer is correct
The correct answer is A. ( [-3,3] ). \( |4x+1|\le 13 \) gives \( -13\le 4x+1\le 13 \). Thus \( -\frac{7}{2}\le x\le 3 \), not the listed interval.
Exam Tip
\( |4x+1|\le 13 \) से \( -13\le 4x+1\le 13 \) मिलता है। इसलिए \( -\frac{7}{2}\le x\le 3 \) नहीं, सही गणना \( -\frac{7}{2}\le x\le 3 \) है।
