( 3(2-x)\le x+10 ) को संख्या रेखा पर दिखाने के लिए सही असमानता कौन सी बनेगी?
Which inequality is formed to show ( 3(2-x)\le x+10 ) on the number line?
Explanation opens after your attempt
A. \( x\ge -1 \)
Concept
Simplifying gives \( 6-3x\le x+10 \), so \( -4x\le 4 \) and \( x\ge -1 \). The sign reverses when dividing by a negative coefficient.
Why this answer is correct
The correct answer is A. \( x\ge -1 \). Simplifying gives \( 6-3x\le x+10 \), so \( -4x\le 4 \) and \( x\ge -1 \). The sign reverses when dividing by a negative coefficient.
Exam Tip
सरलीकरण से \( 6-3x\le x+10 \), इसलिए \( -4x\le 4 \) और \( x\ge -1 \)। ऋणात्मक गुणांक से भाग देते समय चिन्ह पलटता है।
