A dilation is a transformation, with center O and a scale factor of k that is not zero, that maps O to itself and any other point P to P'. The center O is a fixed point, P' is the image of P, points O, P and P' are on the same line.

Thus, a dilation with centre O and a scale factor of k maps the original figure to the image in such a way that the<span> distances from O to the vertices of the image are k times the distances from O to the original figure. Also the size of the image are k times the size of the original figure.

In the dilation of triangle TUV</span>, It is obvious that the image <span>T'U'V' is smaller than the original triangle TUV and hence the scale factor is less than 1.

</span>The ratio of the distances from A to the vertices of the image T'U'V'  to the distances from A to the original triangle TUV is the scale factor.

The scale factor = 3.2 / 4.8 = 2/3

Answer:

c= -2.5-0.5d

Step-by-step explanation:

15=-3(2c+d)

15=-6c+-3d

15+3d=-6c

-2.5-0.5d=c

Arte-miy333 [17]

Answer:

7+2-5=f

Step-by-step explanation:

If he starts on the 7 floor, then he is seven above ground, and that would clarify as a positive number. He then goes up 2 floors, which means we would add 2 to the original number. Going down five would mean we would subtract, because he is getting closer to zero, which is ground level. <em>F</em> represents the floor he is on now.

Hope this helps! (Brainliest please!)
