Graph the image of the given triangle under a dilation with a scale factor of −2 and center of dilation (0, 0) .
Ronch [10]

To dilate an object means to enlarge or reduce the size of the object. The scale factor will determine how much larger or smaller the object will become.  If this factor is greater than 1, the object will increase in size. Otherwise, if the factor is less than 1, the object will decrease in size. So, the dilated object will be similar to its original. On the other hand, when corresponding points of the original and dilated figures are connected by straight lines, the center of dilation is the point where all the lines meet. In this problem, the center is (0, 0). When the center is the origin we need to multiply all the original coordinates of the object by the scale factor given. So:


A(-4, 1) \rightarrow A'=-2(-4,1) \rightarrow A'(8,-2) \\ \\ B(-3, -4) \rightarrow B'=-2(-3,-4) \rightarrow B'(6,8) \\ \\ C(-2, -2) \rightarrow C'=-2(-2,-2) \rightarrow C'(4,4)


So, the graph of the dilated triangle is shown in the Figure below

40 POINTS FOR THIS (HELP)(Bad at algebra) - In two or more complete sentences, compare the number of x-intercepts in the graph o
DochEvi [55]
Your second equation has 2 x-intercepts because its curve goes beneath the x-axis, meaning it crosses the x-axis twice. Your first equation has only one x intercept because its vertex touches the x-axis. The transformation that occurred was a vertical shift downwards, (since the image function has that little -7 at the end : )   )

\mathsf{\dfrac{140+96+13}{3}}

\mathsf{140+36+13}

\mathsf{140 + 96 = \bf 236}

\mathsf{236 + 13}

\mathsf{ = \bf 249}

\mathsf{\dfrac{249}{3}}

\mathsf{= \bf 83}

\boxed{\boxed{\large\textsf{Possible answer: \huge \bf 83}}}\huge\checkmark
