Choose the solution set of the compound inequality (-5\le 2-3x<11).द्वि-असमीका (-5\le 2-3x<11) का समाधान समुच्चय चुनिए।
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (-3<x\le \frac{7}{3})(-3<x\le \frac{7}{3})
We get (-7\le -3x<9), and dividing by (-3) reverses the order, so (-3<x\le \frac{7}{3}). Division by a negative changes the direction of a compound inequality.(-7\le -3x<9) मिलता है और (-3) से भाग देने पर क्रम पलटता है, इसलिए (-3<x\le \frac{7}{3})। परीक्षा में ऋणात्मक भाग से द्वि-असमीका की दिशा बदलती है।
