असमानता \(9-2x\le 1\) का हल क्या है?
What is the solution of the inequality \(9-2x\le 1\)?
Explanation opens after your attempt
A. \(x\ge 4\)
Concept
Subtracting (9) from \(9-2x\le 1\) gives \(-2x\le -8\), and dividing by (-2) gives \(x\ge 4\). The sign reverses when dividing by a negative number.
Why this answer is correct
The correct answer is A. \(x\ge 4\). Subtracting (9) from \(9-2x\le 1\) gives \(-2x\le -8\), and dividing by (-2) gives \(x\ge 4\). The sign reverses when dividing by a negative number.
Exam Tip
\(9-2x\le 1\) में (9) घटाने पर \(-2x\le -8\) मिलता है और (-2) से भाग देने पर \(x\ge 4\) मिलता है। ऋणात्मक संख्या से भाग देने पर चिन्ह उलटता है।
