Solve.The average value of a certain type of automobile was $20,460 in 2006 and depreciated to $14,880 in 2011. Let y be the average value of the automobile in the year x, where x = 0 represents 2006. Write a linear equation that relates value y to year x.
A. y = -1116x + 9300
B. y = - 
x - 14880
C. y = -1116x + 14,880
D. y = -1116x + 20,460
Rewrite the equation in standard form. Find the center and radius of the circle.x2 + y2 - 16x + 15 = 0
A. x2 + (y - 8)2 = 49 center (0, 8), r = 7 B. (x - 8)2 + y2 = 49 center (-8, 0), r = 7 C. (x + 8)2 + y2 = 49 center (-8, 0), r = 7 D. (x - 8)2 + y2 = 49 center (8, 0), r = 7
