The composition d subscript 0, three-halves (x, y) is a composition of d subscript 0, one-half (x, y) is applied to △rst to create the image of △r"s"t", which is not shown. on a coordinate plane, triangle r s t has points (negative 6, 10), (negative 2, 6), and (negative 10, 0). what are the coordinates of point s"? (negative three-halves, nine-halves) (negative nine-halves, fifteen-halves) (nine-halves, negative three-halves) (negative fifteen-halves, 0)
