Figure ABCD is rotated by 180 degrees about the origin in the counterclockwise direction to obtain figure A′B′C′D′:

A coordinate grid is labeled from negative 5 to 0 to 5 on both x and y axes at increments of 1. Figure ABCD has A at ordered pair negative 4, negative 2, B at negative 2, negative 3, C at negative 3, negative 4, D at negative 4, negative 4. Figure A prime B prime C prime D prime has A prime at ordered pair 4, 2, A prime at 2, 3, C prime at 3, 4, D prime at 4, 4.

Ms. Garland bought x number of shirts for the new members of her chorus. The cost for X number of shirts, including $3.99 shipping was $77.49. Each shirt cost $12.25. There was no sales tax on this purchase. Which equation could be used to find X?
A. 3.99(x + 12.25) = 77.49

B. 3.99x + 12.25 = 77.49

C. 12.25 (x + 3.99) = 77.49


D. 12.25x + 3.99 = 77.49

Which function has a greater rate of change?


Function A:

x 1.5 2.5 3.5 4.5 5.5

y –5 0 5 10 15


Function B:

y = –4.5x + 15


Function A has a rate of change of

and Function B has a rate of change of

, so Function

has a greater rate of change.
