How will the inequality (-4x+7\ge 19) be represented on the number line?असमानता (-4x+7\ge 19) को संख्या रेखा पर कैसे दिखाया जाएगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (x\le -3), closed dot at (-3) shaded left(x\le -3), (-3) पर बंद बिंदु और बाईं ओर
From (-4x\ge 12), dividing by a negative gives (x\le -3). In exams, reverse the inequality sign when dividing by a negative.(-4x\ge 12) में ऋणात्मक संख्या से भाग देने पर (x\le -3) मिलता है। परीक्षा में ऋणात्मक से भाग देने पर असमानता का चिन्ह पलटें।
