असमानता \(\frac{x-10}{-4}\le 3\) का संख्या रेखा हल कौन-सा है?
Which is the number line solution of \(\frac{x-10}{-4}\le 3\)?
Explanation opens after your attempt
Correct Answer
B. \(x\ge-2\), (-2) पर बंद बिंदु और दाईं ओर\(x\ge-2\), closed dot at (-2) shaded right
Concept
Multiplying by (-4) reverses the sign to \(x-10\ge-12\), so \(x\ge-2\). In exams, reverse the sign when removing a negative denominator.
Why this answer is correct
The correct answer is B. \(x\ge-2\), (-2) पर बंद बिंदु और दाईं ओर / \(x\ge-2\), closed dot at (-2) shaded right. Multiplying by (-4) reverses the sign to \(x-10\ge-12\), so \(x\ge-2\). In exams, reverse the sign when removing a negative denominator.
Exam Tip
(-4) से गुणा करने पर चिन्ह पलटकर \(x-10\ge-12\), इसलिए \(x\ge-2\)। परीक्षा में negative denominator हटाते समय sign reverse करें।
