A factory produces 10 cars every 3 hours 1. What is the dependent and independent variable
2. Explain how you know the variables are independent or dependent
3. Is the relationship linear or non linear? Explain your reason
4. Do you think that given enough information you could create a table, graph, and an equation for the function? Why or why not
5. What information would you need to make your table/graph/equation

1)The dependent is the number of cars produced. The independent is the amount of time

2)I know that the number of cars produced is the dependent because it will change whenever the amount of time changes

3)This relationship is linear because as you get more time, you will get more cars

4)I could create a graph because I could plot down these points and find the slope

5) I would need a couple more points to plot

step-by-step explanation:

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.
