Answer:
A (-22,-10) -22/2 =-11 -10/2=-5 rotating would be positive both numbers so A is (11,5)
B 10,8 10/2=5 8/2=4 rotating would be negative both so
B is (-5,-4)
C (-6,4) -6/2=-3 4/2=2 rotating would be to different outcomes so
C is (3,-2)
That whole number is 277,349.
Y = -1 + 3x... y1= 2, y2=5... so the 20th term will be 59. There will be ten pairs (i.e 2,59 equal 61... 5,56 equal 61) so multiply this 61 by 10 and your sum will be 610
