Step-by-step explanation:
General equation of circle:
(x - a)² + (y - b)² = r².
Therefore we have x² + (y - 3.5)² = 12.25.
All real numbers.
No matter what you plug in, there will always be a corresponding y - value.

7p + 2 = 5p + 8
Reorder the terms:
2 + 7p = 5p + 8
Reorder the terms:
2 + 7p = 8 + 5p
Solving
2 + 7p = 8 + 5p
Solving for variable 'p'.
Move all terms containing p to the left, all other terms to the right.
Add '-5p' to each side of the equation.
2 + 7p + -5p = 8 + 5p + -5p</span>
