Answer:

Step-by-step explanation:

3² + 1 = 7? Nopeeeee

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

3 * 3 + 1 = 10.

10 is bigger than 7.

Answer:

Step-by-step 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

$10\neq 7$

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

ratelena [41]

Each of the members must raise at least $69.46.

To start they need to raise $552.50. However, they have already raised 12% of it. They only need to raise 88% of it.

552.50 x 0.88 = 486.2

Divide the remaining amount by 7 to determine how much each individual must raise.

486.2 / 7 = 69.46
