असमानता \(2x-5y\ge 15\) को (y) के रूप में लिखने पर क्या मिलेगा?
What do we get when \(2x-5y\ge 15\) is written in terms of (y)?
Explanation opens after your attempt
Correct Answer
B. \(y\le \frac{2x-15}{5}\)
Concept
\(-5y\ge 15-2x\), and dividing by (-5) reverses the sign to \(y\le \frac{2x-15}{5}\). Dividing by a negative number reverses the inequality sign.
Why this answer is correct
The correct answer is B. \(y\le \frac{2x-15}{5}\). \(-5y\ge 15-2x\), and dividing by (-5) reverses the sign to \(y\le \frac{2x-15}{5}\). Dividing by a negative number reverses the inequality sign.
Exam Tip
\(-5y\ge 15-2x\) और (-5) से भाग देने पर चिह्न बदलकर \(y\le \frac{2x-15}{5}\) होगा। ऋणात्मक संख्या से भाग देने पर चिह्न पलटता है।
