1. If x>5 and y<-1, which of the following statements is true
- A. (x+4y)>1
- B. (x+4y)>1
- C. (x+4y)>1
- D. (x+4y)>1
Answer: Option D
Explanation:
x > 5 and y < -1, we can make the following conclusions:
x + y > 4: Since x is greater than 5 and y is less than -1, their sum will be greater than 4. Therefore, the statement "x + y > 4" is true.
x * y < -5: Since x is greater than 5 and y is less than -1, their product will be less than -5 (because a positive number multiplied by a negative number gives a negative result). Therefore, the statement "x * y < -5" is true.
Therefore, the true statement is "x + y > 4", and the statement "x * y < -5" is also true.
So , the correct Ans is None of these.
