What transformations were applied to ABCD to obtain A'B'C'D? A. Rotate 180 degrees counterclockwise about the origin, then
translate 1 unit down.
B. Rotate 90 degrees counterclockwise about the origin, then
C. Rotate 90 degrees counterclockwise about the origin, then translate 2 units down
D. Rotate 90 degrees counterclockwise about the origin, then translate 2 units up

Me #1 using vocabulary words, including the word “congruent”, state why the measure of angle d is 120 degrees. #2 what is the measure of angle e and why?

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10

Aretha wanted to gather data about the cost of local bowling leagues in her area. she plotted the data and determined that the average bowling league costs consist of a one-time registration fee and a monthly fee modeled by the equation y = 15x + 20. identify and interpret the y-intercept in this model. the y-intercept is 20. this is the cost per month. the y-intercept is 20. this is the cost of registration. the y-intercept is 15. this is the cost of registration. the y-intercept is 15. this is the cost per month.
