Which is the solution of \(x+4\ge 13\)?
A. \(x\ge 9\)
दोनों ओर (4) घटाने पर \(x\ge 9\) मिलता है। जोड़ या घटाव से दिशा नहीं बदलती। / Subtracting (4) from both sides gives \(x\ge 9\). Addition or subtraction does not change the direction.

What is the correct solution of (9-x<4)?
A. (x>5)
(9-x<4) से (-x<-5) और ऋणात्मक से भाग देने पर (x>5)। (-x) हटाते समय चिह्न पलटता है। / From (9-x<4), we get (-x<-5), and dividing by a negative gives (x>5). The sign reverses when removing (-x).

Which is the solution of \(2x+5\le 17\)?
A. \(x\le 6\)
पहले (5) घटाएँ फिर (2) से भाग दें तो \(x\le 6\)। दो चरणों वाले प्रश्न में क्रम सही रखें। / First subtract (5), then divide by (2), giving \(x\le 6\). Keep the order correct in two-step questions.

What is the correct solution of \(15-3x\ge 6\)?
A. \(x\le 3\)
\(15-3x\ge 6\) से \(-3x\ge -9\) और (-3) से भाग देने पर \(x\le 3\)। ऋणात्मक भाग में दिशा बदलती है। / From \(15-3x\ge 6\), we get \(-3x\ge -9\), and division by (-3) gives \(x\le 3\). Negative division changes the direction.

What is the interval form of \(x\le 4\)?
A. (\(-\infty,4]\)
\(x\le 4\) में (4) शामिल है और मान बाईं ओर जाते हैं। इसलिए (\(-\infty,4]\) सही है। / In \(x\le 4\), (4) is included and values go to the left. Therefore (\(-\infty,4]\) is correct.

Which is the interval form of (x>6)?
A. (\(6,\infty\))
(x>6) में (6) शामिल नहीं है और मान दाईं ओर हैं। इसलिए (\(6,\infty\)) सही है। / In (x>6), (6) is not included and values lie to the right. So (\(6,\infty\)) is correct.

Which option correctly describes \(0\le x<10\)?
A. (x) (0) या उससे बड़ा और (10) से छोटा है(x) is (0) or more and less than (10)
\(0\le x<10\) में (0) शामिल है पर (10) शामिल नहीं है। संयुक्त असमानता को दोनों तरफ से पढ़ें। / In \(0\le x<10\), (0) is included but (10) is not included. Read a compound inequality from both sides.
