Math is so hard:

For which function is the ordered pair (4, 12) not a solution?

1. y = 3 x
2. y = 16 - x
3. y = x + 8
4. y = 8 - x

what’s the answer?

Answer:

4. y = 8 - x

Explanation:

The question asks for which function is the ordered pair not a solution?

We need to substitute the ordered pair (4, 12) into x and y.

1. 12 = 3(4) (correct)

2. 12 = 16 - 4 (correct)

3. 12 = 4 + 8 (correct)

4. 12 = 8 - 4 (incorrect)

Therefore, the solution to your question is option 4.
