Answer: (1,-2)

Explanation:

To check which of the given ordered pairs satisfy the given system of nonlinear inequalities, we will substitute the values of x and y from each ordered pair and then check if the inequalities hold true or not. Let's check one by one.

For the ordered pair (1,-2):

7 - 2(x-1)² ≤ 25 - y

7 - 2(1-1)² ≤ 25 - (-2)

7 ≤ 25 + 2

7 ≤ 27 (This is true)

2 ≤ -y

2 ≤ -(-2)

2 ≤ 2 (This is true)

Therefore, (1,-2) satisfies the given system of nonlinear inequalities.

For the ordered pair (1,-3):

7 - 2(x-1)² ≤ 25 - y

7 - 2(1-1)² ≤ 25 - (-3)

7 ≤ 28 (This is true)

2 ≤ -y

2 ≤ -(-3)

2 ≤ 3 (This is true)

Therefore, (1,-3) does not satisfy the given system of nonlinear inequalities.

For the ordered pair (1,0):

7 - 2(x-1)² ≤ 25 - y

7 - 2(1-1)² ≤ 25 - (0)

7 ≤ 25 (This is true)

2 ≤ -y

2 ≤ -(0)

2 ≤ 0 (This is not true)

Therefore, (1,0) does not satisfy the given system of nonlinear inequalities.

For the ordered pair (0,0):

We do not have the value of x for this ordered pair, so we cannot check whether it satisfies the given system of nonlinear inequalities.

Hence, the ordered pair that satisfies the given system of nonlinear inequalities is (1,-2).
