Which constraint correctly represents the situation "Mixture of x and y must be at least 8 units"?
- A \(x+y > 8\)
- B \(x+y < 8\)
- C \(x+y \leq 8\)
- D \(x+y \geq 8\)
Answer & Solution
Correct Answer
(D) \(x+y \geq 8\)
Step-by-step Solution
Detailed explanation
The phrase "at least" means the value can be exactly 8 or any amount greater than 8. Therefore, the correct mathematical representation is \(x+y \geq 8\). (D) \(x+y \geq 8\)
