Mode = 93
I got this wrong just to help you figure out the right answer. (I just did not answer and this is the final result)
Answer:
A geometric object is represented by its vertices (as position vectors) A geometric transformation is an operation that modifies its shape, size, position, orientation etc with respect to its current configuration operating on the vertices (position vectors).
-9(5-4v+7v)
=-9(5+3v)
=-45-27v
-45-27v is the final answer.
