A rotation 270° counterclockwise about the origin is the same as rotation 90° clockwise about the origin and has a rule:
(x,y)→(y,-x).
Then:
- D(−2,4)→D'(4,2)
- E(4,7)→E'(7,-4)
- F(10,3)→F'(3,-10)
- G(8,0)→G'(0,-8)
Answer: the coordinates of vertices of quadrilateral D′E′F′G′ are D'(4,2), E'(7,-4), F'(3,-10), G'(0,-8).
8 over 9
= 8/9
= 8:9
Final answer: 8:9~
Yes she is right. i turned it into a fraction which would be 18/15. then divide 18 by 15, which is 1.2 . then multiply 1.2 by 100
