O None of the other answers are correct O (0,4),(0,0), (3,0) O (3.0), (0,0).(-4,0) 0 (0,4),(0, 0), (-3,0) O (4,0).(0,0). (4,3)​

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.

so, converting firstly the mixed fractions to improper fractions and then "adding".
