If (x\in\mathbb{Z}) and (|x+2|\le 5), how many integer points will be on the number line?यदि (x\in\mathbb{Z}) और (|x+2|\le 5), तो संख्या रेखा पर कितने पूर्णांक बिंदु होंगे?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (11)(11)
(|x+2|\le5) gives (-7\le x\le3), so there are (11) integers. In exams, count endpoints in a closed interval.(|x+2|\le5) से (-7\le x\le3), इसलिए कुल (11) पूर्णांक हैं। परीक्षा में closed interval में endpoints भी गिनें।
