द्वि-असमीका \(-5\le 2-3x<11\) का समाधान समुच्चय चुनिए।
Choose the solution set of the compound inequality \(-5\le 2-3x<11\).
Explanation opens after your attempt
A. \(-3<x\le \frac{7}{3}\)
Concept
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.
Why this answer is correct
The correct answer is A. \(-3<x\le \frac{7}{3}\). 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.
Exam Tip
\(-7\le -3x<9\) 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।
