what translation and dilation prove these two circles are similar by mapping circle c onto circle d?
circle c: center at (1, 3) and radius 4 to circle d: center at (-2, 5) and radius 7
a
translation: 2 units left and 3 units up
dilation: scale factor =
b

translation: 3 units right and 2 units up
dilation: scale factor =
c

translation: 3 units left and 2 units up
dilation: scale factor =
d

translation: 3 units right and 2 units down
dilation: scale factor =
