Which inequality has the solution set (−∞, 2]?किस असमता का हल-समुच्चय (−∞, 2] है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 3x − 6 ≤ 03x − 6 ≤ 0
For option A, adding 6 gives 3x ≤ 6, and dividing by 3 gives x ≤ 2. This is exactly the interval (−∞, 2], which includes 2.विकल्प A में दोनों पक्षों में 6 जोड़ने पर 3x ≤ 6 मिलता है। 3 से भाग देने पर x ≤ 2 प्राप्त होता है। यह ठीक अंतराल (−∞, 2] है, जिसमें 2 शामिल है।
