Step-by-step explanation:
For some point X, center C, and dilation factor k, the image point X' will be ...
... X' = C + k(X -C)
Assuming you want k=12 in both cases, for the written problem, the first point is ...
... X' = (-3, 0) + 12((-5, 4) -(-3, 0)) = (-3, 0) +12(-2, 4)
... = (-3, 0) +(-24, 48)
... X' = (-27, 48)
_____
In the problem in the image, the lower right point will be ...
... Q' = C + k(Q -C)
... Q' = (-3, 1) +12((2, 2) -(-3, 1)) = (-3, 1) + 12(5, 1)
... = (-3, 1) + (60, 12)
... Q' = (57, 13)
