For a satellite orbiting Earth, the time required to complete a single orbit is known as the period. The period P, in hours, is related to the distance D, in miles, from the center of Earth by the formula 
.
As the period increases, so does the distance. What can you say about the rate of increase in distance as period increases? A graph of D versus P can help you answer this question.
?
A. Distance increases at an increasing rate as period increases.
B. Distance increases at a decreasing rate as period increases.
C. A point of inflection is reached.
D. None of the above.

Solve the system of equations by Gaussian elimination. If there is an unlimited number of solutions, find two of them.-3x - y - 9z = -21 2x + 9y - 4z = 79 6x - 2y + z = -11
A. Inconsistent B. x = 1, y = 1, z = 9 C. Unlimited: x = 1, y = 9, z = 1, x = 1, y = 1, z = 9 D. x = 1, y = 9, z = 1
