Answer:

No

Explanation:

To know if (3, 7) is a solution, plug 3 into the x and 7 into the y.


(3)^(2) +1=7

9 + 1 = 7


10\\eq 7

Therefore, (3, 7) is not a solution.

Answer:

No

Explanation:

3² + 1 = 7? Nopeeeee

3 * 3 = 9, that alone is bigger than 7.

3 * 3 + 1 = 10.

10 is bigger than 7.
