1 = 2

Prove:

RA = RB

1. line RS || segment AB, ∠1=∠2
If lines ||, corresponding ∠'s are =
2. ∠B = ∠1
Substitution
3. ∠A = ∠2
If two ∠'s of a triangle are =, sides opposite are =
4. ∠A = ∠B
Given
5. RA = RB
If lines ||, alternate interior ∠'s =

sorry, i can't understand your question. will later if you describe more clearly!

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.

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
