6x - 5y < 11

-3x + 2y < -8
is (5, 4) a solution of the system of inequalities shown ahon?

Yes

Step-by-step explanation:

To determine if (5, 4) is a solution, substitute the x and y values into the left side of the inequalities and compare the result to the right side.

6(5) - 5(4) = 30 - 20 = 10 < 11 ← True

- 3(5) + 2(4) = - 15 + 8 = - 7 < - 8 ← True

Since both inequalities are true then (5, 4) is a solution to the system

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
