Ответ:
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
Ответ:
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!
