Can someone me out. i have a lot of math questions to do and i don't understand this topic. the question i need with is attached. i would greatly appreciate it if someone could me.

counterclockwise rotation about the origin of 270°

the coordinates of Q(6, 2), R(4, 9), S(2, 7)

the coordinates of Q'(2, - 6), R'(9, - 4), S'(7, - 2)

Note that the x-coordinate of the image is the y-coordinate of the original and the y-coordinate of the image is the negative of the x-coordinate of the original

This is a counterclockwise rotation about the origin of 270°

a point (x, y) → (y, - x) ← in general

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
