(x, y) (0.5x, 1.5y) G (7.5, 3) endstream endobj 131 0 obj <>stream (x, y) -> (x+6, y-3) After dilation algebraic rule: (x, y) -> (1/3x, 1/3y), Question 4. a. Multiply each coordinate of the vertices of rectangle FGHI by 1, 5 to find the vertices of the dilated image. (x, y) (y, -x) Cursos focados em mquinas pesadas. d. (x, y) -> (6x, 6y), Explanation: Sketch triangle ABC and ABC for the dilation (x, y) (-2x, -2y). The dimension of a new room on a blueprint is now: (3, 2), (1, 2), (3, 1), (1, 1) In the given expression, we can notice that the x coordinate is multiplied with \(\frac{2}{3}\). (3, 2), (1, 2), (3, 1), (1, 1) Worksheets are Middle school math series course 2, Chapter 7, Algebraic representations of dilations, Algebraic representations of dilations, Conjectures. Identify a sequence of two transformations that will transform figure A into the given figure. How would a dilation with scale factor 1 affect the preimage? The blue square is the preimage. The center of dilation is the origin.
