Which number-line representation is correct for the inequality \(x\le 3\)?असमानता \(x\le 3\) का संख्या रेखा पर सही निरूपण कौन-सा है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: A closed point at 3 and shading to the left3 पर भरा बिंदु और बाईं ओर छायांकन
In \(x\le3\), the endpoint 3 is included, so it is shown by a closed point. Numbers smaller than 3 lie to the left, so that side is shaded. Exam tip: use a closed point for \(\le\) or \(\ge\), not an open point.\(x\le3\) में 3 स्वयं हल में शामिल है, इसलिए 3 पर भरा बिंदु बनता है। 3 से छोटी सभी संख्याएँ बाईं ओर होती हैं, अतः वहीं छायांकन होगा। परीक्षा टिप: \(\le\) या \(\ge\) के लिए हमेशा भरा बिंदु लें।
