How might a drop in price for washing machines affect the demand for dryers? a) the demand for dryers would have no relation to the changing prices of washing machines. b) the demand for dryers would most likely increase as the price for washing machines dropped. c) the demand for dryers would most likely decrease as the price for washing machines dropped. d) the demand for dryers would only be affected by an increase in the price of washing machines. b

the answer is B

Step-by-step explanation:

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

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.
