A circle has the equation x2+ 12x+y2 -8y = 73. (a) Determine the coordinates of the center of the circle. Show how you arrived at
your answer.
(b) Does the point (16, -1) lie on this circle. Show why or why not

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.

there are no figures how am i supposed to answer this question

step-by-step explanation:

1 mph

step-by-step explanation:

if the question is asking how much does she drive per mile then,

13 / 13 = 1 mph
