D. \(18\le x\le 25\)
दोनों बंद सिरे बताते हैं कि दोनों सीमाएँ शामिल हैं। इसलिए दोनों ओर बराबरी सहित असमता होगी। / Both closed endpoints show that both boundaries are included. So inclusive inequalities are used on both sides.

Which number line representation correctly shows \(x\le -22\)?
A. (-22) पर भरा वृत्त और बाईं ओर तीरClosed circle at (-22) and arrow left
\(x\le -22\) में (-22) शामिल है और उससे छोटी संख्याएँ ली जाती हैं। इसलिए भरा वृत्त बाईं ओर तीर के साथ होगा। / In \(x\le -22\), (-22) is included and smaller numbers are taken. So a closed circle with a left arrow is used.

What does the interval (\(-\infty,-6]\cup[10,\infty\)) show on the number line?
B. \(x\le -6\) या \(x\ge 10\)\(x\le -6\) or \(x\ge 10\)
पहला भाग \(x\le -6\) और दूसरा भाग \(x\ge 10\) देता है। \(\cup\) दोनों भागों का मिलन दिखाता है। / The first part gives \(x\le -6\) and the second gives \(x\ge 10\). The symbol \(\cup\) shows the union of both parts.

C. ((1,8])
खाली वृत्त (1) को बाहर रखता है और भरा वृत्त (8) को शामिल करता है। इसलिए ((1,8]) सही है। / The open circle excludes (1), and the closed circle includes (8). Therefore ((1,8]) is correct.

Which option shows the union of (x<6) and (x>6)?
A. (\(-\infty,6\)\cup\(6,\infty\))
दोनों भाग (6) को शामिल नहीं करते। इसलिए (6) पर खाली वृत्त और दोनों ओर छायांकन होगा। / Both parts exclude (6). So (6) has an open circle and both sides are shaded.

What is the correct meaning of ([-14,-14]) on the number line?
A. सिर्फ (-14) पर भरा बिंदुOnly a closed point at (-14)
समान सीमाओं वाला बंद अंतराल केवल उसी संख्या को शामिल करता है। इसलिए (-14) पर भरा बिंदु बनेगा। / A closed interval with equal endpoints includes only that number. Therefore a closed point is drawn at (-14).

Which interval is correct for \(x\le \frac{5}{6}\)?
A. (\(-\infty,\frac{5}{6}]\)
\(\le\) सीमा \(\frac{5}{6}\) को शामिल करता है और बाईं ओर की संख्याएँ लेता है। इसलिए (\(-\infty,\frac{5}{6}]\) सही है। / \(\le\) includes the boundary \(\frac{5}{6}\) and takes numbers to the left. Therefore (\(-\infty,\frac{5}{6}]\) is correct.

If the representation of \(x\ge -3\) is to be drawn, what mark is made at (-3)?
B. भरा वृत्तClosed circle
\(x\ge -3\) में (-3) समाधान का भाग है। शामिल सीमा पर भरा वृत्त बनाया जाता है। / In \(x\ge -3\), (-3) is part of the solution. An included boundary is shown by a closed circle.

Which integer is the smallest member of the interval ((-9,-3])?
B. (-8)
(-9) शामिल नहीं है इसलिए उसके बाद पहला पूर्णांक (-8) होगा। खुले सिरे को सदस्य न मानें। / (-9) is not included, so the first integer after it is (-8). Do not count an open endpoint as a member.

Which integer is the greatest member of the interval ([5,12))?
C. (11)
(12) शामिल नहीं है इसलिए उससे पहले का सबसे बड़ा पूर्णांक (11) होगा। खुले दाएँ सिरे को उत्तर न मानें। / (12) is not included, so the greatest integer before it is (11). Do not take the open right endpoint as the answer.
