Write the algebraic representation of the dilation shown. Write two algebraic representations, one for the dilation to the green square and one for the dilation to the purple square. Type below: (-3, -4) I know that triangle ABC is a dilation of triangle ABC because the ratios of the corresponding x-coordinates are _______ and the ratios of the corresponding y-coordinates are _______. Answer: 5/2 = 2.5 Since it changes the size of a figure, it has no something to do with the changes when it comes to the angles of the image. Options: _____________, Answer: A_____ B_____ C_____ 2. x = 3 Represent Real-World Problems The blueprints for a new house are scaled so that \(\frac{1}{4}\) inch equals 1 foot. _____________, Answer: The vertices of the dilated image are A'(1, 1), B'(3, 1), and C'(1, 3). _____________, Answer: 4), (3.-3)) -> C'(12, -9), Question 7. One inch on the blueprint represents how many inches in the actual house? Draw Conclusions A figure undergoes a sequence of transformations that include dilations. Question 3. (3, 8) (-2, 1) The figure and its final image are congruent. Critical Thinking MNOP has vertices at M'(3, 4), N'(6, 4), O'(6, 7), and P'(3, 7). AB/AB = 2/4 = 1/2 325. . lesson 10 2 algebraic representations of dilations. ________ inches C'(12, -9), Explanation: (x, y) ( x, -y) All the explanations are given by the best online maths experts. Explain your reasoning. Critique Reasoning The set for a school play needs a replica of a historic building painted on a backdrop that is 20 feet long and 16 feet high. h24T0P044P06R After the sequencing of transformations, reflection over the y-axis. 10.2 Algebraic Representations of Dilations 8th grade Played 0 times Mathematics 4 hours ago by hhudson_96017 0 Save Edit Live modes Start a live quiz Asynchronous learning Assign homework 10 questions Preview Show answers Question 1 180 seconds Q. Dilate the figure by a scale factor of 3 with the origin as the center of dilation. Critical Thinking MNOP has vertices at M(3, 4), N(6, 4), O(6, 7), and P(3, 7). This will be followed by the.
