Drag each graph to show whether it is a function of x or not a function of x. If there is not enough information to tell, drag the graph into the box under "Not Enough Information"

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.

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.

y/x of point b= y/x of point a

step-by-step explanation:

(i got the same question, this was the correct answer.)
