अंतराल \((-\infty, -\frac{1}{2})\) संख्या रेखा पर किस असमता को दर्शाता है?
Which inequality is represented by the interval \((-\infty, -\frac{1}{2}]\) on the number line?
Explanation opens after your attempt
Correct Answer
B. \(x\le -\frac{1}{2}\)
Concept
The square bracket shows that \(-\frac{1}{2}\) is included, and the values extend toward \(-\infty\). Hence \(x\le -\frac{1}{2}\) is correct.
Why this answer is correct
The correct answer is B. \(x\le -\frac{1}{2}\). The square bracket shows that \(-\frac{1}{2}\) is included, and the values extend toward \(-\infty\). Hence \(x\le -\frac{1}{2}\) is correct.
Exam Tip
वर्ग कोष्ठक बताता है कि \(-\frac{1}{2}\) शामिल है और \(-\infty\) की ओर छोटी संख्याएँ हैं। इसलिए \(x\le -\frac{1}{2}\) सही है।
