When graphed, the three lines y=-x+2,y=2x-1 and y= x-2 intersect in such a way that they form a triangle. What are the coordinates of the the three vertices of this triangle? A. (2,0),(0,2), and (-1,-3)
B.(0,2),(2,0), and (1,-1)
C. (1,1), (2,0), and (-1,-3)
D(1,1), (0,2), and (-1,-3)
E.(2,0), (1,-1), and (-1,-3)​

White shapes and black shapes are used in a game. some of the shapes are circles. while the rest are squares. the ratio of the number of white shapes to the number of black shapes is 5: 11. the ratio of the number of white cicrles to the number of white squares is 3: 7. the ratio of the number of black circles to the number of black squres is 3: 8. work out what fraction of all the shapes are circles.
