Question

Is(2, 5)asolutiontotheinequality 2x + 3y ≥ 20 ?

Answer 1

Answer:

no

Step-by-step explanation:

2x + 3y ≥ 20

Substitute the point (2,5) in for x and y and see the inequality is true

2(2) +3(5) ≥ 20

4 + 15 ≥ 20

19 ≥ 20  

This is not true, so (2,5) is not a solution

Answer 2

Steps to solve:

2x + 3y ≥ 20; x = 2, y = 5

~Substitute

2(2) + 3(5) ≥ 20

~Simplify

4 + 15 ≥ 20

~Simplify

19 ≥ 20

The inequality is NOT true. Therefore, (2,5) is NOT a solution to the inequality.

Best of Luck!
