Answer:
22
Step-by-step explanation:
22
Step-by-step explanation:
x² + 12x + y² - 8y = 73
(x² + 12x + 36) + (y² - 8y + 16) = 73 + 36 + 16
(x + 6)² + (y - 4)² = 125.
Hence the coordinates of the center is (-6, 4).
Since (16 + 6)² + (-1 - 4)² = 22² + (-5)² = 509 and 509 is not equal to 125, (16, -1) does not lie on the circle.
