As the wheel makes this 270 degree counterclockwise rotation about the origin, the y-coordinate of the first car decreases from 80 to 0 and then further from 0 to -80, and finally increases to 0.
The x-coordinate decreases from 0 to -80 and then increases to 0; from there it increases further to 80.
Thus, the coordinates of the first car, after this 270-degree rotation, are (80, 0).
Zero because -12 does not equal 12
Yes.The second factor is the difference of 2 squares,
so the second factor alone becomes
(x² - 4) = (x + 2) (x - 2)
Answer:
25% is the answer because 25 x 4 = 100% and 20x4= 80
