Algebra practice question
Which ordered pair (x, y) satisfies BOTH x + y ≤ 6 and y ≥ 2x − 4?
- A. (2, 3)Correct
- B. (4, 3)
- C. (5, 0)
- D. (1, 6)
Answer: A. (2, 3)
(2, 3): 5 ≤ 6 ✓ and 3 ≥ 0 ✓.
Why the other answers are wrong
- B. (4, 3)
- (4, 3): 7 ≤ 6 is false.
- C. (5, 0)
- (5, 0): 0 ≥ 6 is false.
- D. (1, 6)
- (1, 6): 7 ≤ 6 is false.
