Which is the correct interval on the number line for (1\le\frac{2x+3}{5}\le 3)?असमानता (1\le\frac{2x+3}{5}\le 3) का संख्या रेखा पर सही अंतराल कौन-सा है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ([1,6])([1,6])
(5\le2x+3\le15) gives (2\le2x\le12), so (1\le x\le6). In exams, a closed compound inequality gives a closed interval.(5\le2x+3\le15) से (2\le2x\le12), इसलिए (1\le x\le6)। परीक्षा में बंद संयुक्त असमानता से बंद interval मिलता है।
