4. Triangle PQR has vertices P(2,4), Q(8,8) and R(8,4). On the grid provided, graph the dilation of
Triangle PQR using a scale factor of – and the
4
origin as the center of dilation.
What are the coordinates of Triangle P'Q'R'?
A P’(-0.5, -1) Q’(2, 2) R’(2,1)
B P’(0.5, 1) Q’(2, 2) R’(2,1)
C P’(0.5, 1) Q’(-2, 2) R'(-2,1)
D P’(0.5, -1) Q’(2, -2) R’(2, 1)

answer: 43/157

this is the answer and if you try to prove me wrong your a meanie

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 answer is b.)
