यदि असमानता \(kx-6\le 2x+3\) का हल \(x\ge -3\) है, तो (k) का मान क्या है?
If the inequality \(kx-6\le 2x+3\) has solution \(x\ge -3\), what is the value of (k)?
Explanation opens after your attempt
A. (k=-1)
Concept
We have ((k-2)x\le9). To get \(x\ge-3\), need (k-2<0) and \(\frac{9}{k-2}=-3\), so (k=-1).
Why this answer is correct
The correct answer is A. (k=-1). We have ((k-2)x\le9). To get \(x\ge-3\), need (k-2<0) and \(\frac{9}{k-2}=-3\), so (k=-1).
Exam Tip
((k-2)x\le9) है। \(x\ge-3\) पाने के लिए (k-2<0) और \(\frac{9}{k-2}=-3\), इसलिए (k=-1)।
