Rst is dilated about the origin, 0, to create r’s’t. point r is located at (3,9) and point r’ is located at (1.2, 3.6). which scale factor was used to perform the dilation?

0.4

Step-by-step explanation:

Since the dilatation is about the origin, then dividing the coordinates of the image R' by the coordinates of the original point R gives the scale factor

scale factor = = = 0.4

the fist one is not equalvalent but i think th second one isand the third isnt definetly or the last one is i think. hope this !

step-by-step explanation:

160
