Given ABC, use a dilation with the center at the
origin to make a similar triangle with side lengths three
times as large. What are the coordinates of C' of the
image?
(-6,3)
(-3, 6)
(3,-6)
(6,-3)

(6,-3)

Trust me, I just checked the answer.

I think it is (6,-3).

Step-by-step explanation:

I hope this helps.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

  the correct choice is marked

step-by-step explanation:

the first two graphs show multiple turning points. the last graphs matches the description in every detail.
