5x - 9y ≥ 8\n7x - 4y < 10\nis (2,2) a solution of the system?\nchoose 1 answer:\na yes\nb no

Explanation:

Step1: Substitute into first inequality

Substitute $x = 2$ and $y=2$ into $5x - 9y\geq8$. $5\times2-9\times2=10 - 18=-8$. Since $-8\ngeq8$, the point $(2,2)$ does not satisfy the first - inequality.

Step2: Conclusion

Since the point $(2,2)$ does not satisfy one of the inequalities in the system, it is not a solution of the system.

Answer:

B. No
