यदि \(-9\leq 3x-6<12\) है तो (x) का सही अंतराल कौन सा है?
If \(-9\leq 3x-6<12\), which interval for (x) is correct?
Explanation opens after your attempt
A. ([-1,6))
Concept
Adding (6) gives \(-3\leq 3x<18\), then \(-1\leq x<6\). Apply the same operation to all parts of a compound inequality.
Why this answer is correct
The correct answer is A. ([-1,6)). Adding (6) gives \(-3\leq 3x<18\), then \(-1\leq x<6\). Apply the same operation to all parts of a compound inequality.
Exam Tip
(6) जोड़ने पर \(-3\leq 3x<18\) और फिर \(-1\leq x<6\) मिलता है। संयुक्त असमता में दोनों ओर समान क्रिया करें।
