असमानता \(|3x-2|\le 10\) का संख्या रेखा पर सही अंतराल कौन-सा है?
Which is the correct interval on the number line for \(|3x-2|\le 10\)?
Explanation opens after your attempt
B. \([- \frac{8}{3},4]\)
Concept
\(-10\le3x-2\le10\) gives \(-8\le3x\le12\), so \(-\frac{8}{3}\le x\le4\). In exams, keep both endpoints closed for \(\le\).
Why this answer is correct
The correct answer is B. \([- \frac{8}{3},4]\). \(-10\le3x-2\le10\) gives \(-8\le3x\le12\), so \(-\frac{8}{3}\le x\le4\). In exams, keep both endpoints closed for \(\le\).
Exam Tip
\(-10\le3x-2\le10\) से \(-8\le3x\le12\), इसलिए \(-\frac{8}{3}\le x\le4\)। परीक्षा में \(\le\) होने पर दोनों सिरे बंद रखें।
