Math Problem Statement

Which ordered pair is a solution to the inequality 7x - 3y > 10?

Solution

We are tasked with finding which ordered pair satisfies the inequality 7x3y>107x - 3y > 10. Let's check each pair by substituting xx and yy values into the inequality:

1. For (2,1)(2, 1):

7(2)3(1)=143=117(2) - 3(1) = 14 - 3 = 11 Since 11>1011 > 10, this pair satisfies the inequality.

2. For (1,0)(1, 0):

7(1)3(0)=70=77(1) - 3(0) = 7 - 0 = 7 Since 7107 \not> 10, this pair does not satisfy the inequality.

3. For (1,1)(1, -1):

7(1)3(1)=7+3=107(1) - 3(-1) = 7 + 3 = 10 Since 101010 \not> 10, this pair does not satisfy the inequality.

4. For (3,4)(3, 4):

7(3)3(4)=2112=97(3) - 3(4) = 21 - 12 = 9 Since 9109 \not> 10, this pair does not satisfy the inequality.

Thus, the correct answer is the pair (2, 1).
