The Kendal Company manufactures automobile engine parts. Running the manufacturing operations requires 12 watts (units of electricity per hour). The amount of electricity required to run the manufacturing operations and lighting the facility is given by y = 12x + 24, where x is the number of hours of manufacturing and y is the amount of electricity expended. How much electricity is used on a day when no parts are manufactured? (x 0, y 0). . A. 2 watts. B. 12 watts. C. 20 watts. D. 24 watts . E. 30 watts.

Respuesta :

24 because when you plug in 0 for both x and y: 

0=12(0)+24 
12*0=0, leaving you with 24.

We are given with the equation y = 12x + 24  where 12 is equivalent to the 12 watts of electricity and x is the number of hours of manufacturing and y is the amount of electricity expended. When there are no parts manufactured, then x = 0. Substituting, y = 24. hence the answer is 24 watts.
