Taking (-1\le 2x+3\le 11) and (x>0) together, which interval is obtained on the number line?असमानता (-1\le 2x+3\le 11) और (x>0) को साथ लेने पर संख्या रेखा पर कौन-सा interval मिलेगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ((0,4])((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.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।
