Taking \(-1\le 2x+3\le 11\) and (x>0) together, which interval is obtained on the number line?
Explanation opens after your attempt
Correct Answer
B. ((0,4])
Concept
The first inequality gives \(-2\le x\le4\), and the second gives (x>0), so the common part is ((0,4]). In exams, apply the extra condition as an intersection.
Why this answer is correct
The correct answer is B. ((0,4]). The first inequality gives \(-2\le x\le4\), and the second gives (x>0), so the common part is ((0,4]). In exams, apply the extra condition as an intersection.
Exam Tip
पहली असमानता से \(-2\le x\le4\) और दूसरी से (x>0), इसलिए common भाग ((0,4]) है। परीक्षा में extra condition लगाकर intersection लें।
