This question refers to a figure in the original PDF.
- (A)– x < – 5
- (B)– x ≤ – 5
- (C)– x > – 5
- (D)– x ≥ – 5 20. Given that x, y and b are real numbers and x < y, b < 0, then x y x y (A) < (B) ≤ b b b b x y x y (C) > (D) ≥ b b b b 21. If – 3x + 17 < – 13, then (A) x ∈ (10, ∞) (B) x ∈ [10, ∞) (C) x ∈ (– ∞, 10] (D) x ∈ [– 10, 10) 22. If x is a real number and | x | < 3, then (A) x ≥ 3 (B) – 3 < x < 3 (C) x ≤ – 3 (D) – 3 ≤ x ≤ 3 23. x and b are real numbers. If b > 0 and | x | > b, then (A) x ∈ (– b, ∞) (B) x ∈ [– ∞, b) (C) x ∈ (– b, b) (D) x ∈ (– ∞, – b) ∪ (b, ∞) 24. If x − 1 > 5, then (A) x ∈ (– 4, 6) (B) x ∈ [– 4, 6] (C) x ∈ [– ∞, – 4) ∪ (6, ∞) (D) x ∈ [– ∞, – 4) ∪ [6, ∞) 25. If x + 2 ≤ 9, then (A) x ∈ (– 7, 11) (B) x ∈ [– 11, 7] (C) x ∈ (– ∞, – 7) ∪ (11, ∞) (D) x ∈ (– ∞, – 7) ∪ [11, ∞) 26. The inequality representing the following graph is: Fig 6.7 (A) | x | < 5 (B) | x | ≤ 5 (C) | x | > 5 (D) | x | ≥ 5 Solution of a linear inequality in variable x is represented on number line in Exercises
