The ordered pair is in the solution set of 2x ā 5y ā„ 10 is (5,0) and this can be determined by using the arithmetic operations.
Given :
Inequality Ā -- Ā 2x ā 5y ā„ 10
The following steps can be in order to determine the ordered pair is in the solution set of 2x ā 5y ā„ 10:
Step 1 - Write the given inequality.
2x ā 5y ā„ 10
Step 2 - Substitute each point given in the option to the inequality.
Step 3 - Substitute (x = 0) and (y = 5) in the given inequality.
2(0) ā 5(5) ā„ 10
-25 ā„ 10 (Not True)
Step 4 - Substitute (x = 5) and (y = 0) in the given inequality.
2(5) ā 5(0) ā„ 10
10 ā„ 10 (True)
Step 5 - Substitute (x = -2) and (y = 5) in the given inequality.
2(-2) ā 5(5) ā„ 10
-29 ā„ 10 (Not True)
Step 6 - Substitute (x = -5) and (y = 2) in the given inequality.
2(-5) ā 5(2) ā„ 10
-20 ā„ 10 (Not True)
Therefore, the correct option is B).
