Question

The equation M(x,y)=56+0.2x-0.8y gives the mileage (in mpg) are the new car as the function of tire pressure x (in psi) and speed y (in mph). Find M(36,42). (include the appropriate units) and explain what it means.

The equation M(x,y) = 56 +0.2% - 0.8y gives the mileage (in mpg) of a new car as a function of tire pressure x (in psi) and speed y ſin mph). Find M(36,42) (include the appropriate units) and explain what it means. M[36,42)-01 (Type an integer or a decimal.) Explain what the answer in the previous step means. Select the correct choice below and fill in the answer boxes within your choice (Type integers or decimals.) O A. Mileage is mpg at a tire pressure of psi and a speed of mph OB. Increasing the tire pressure by one psi and maintaining a speed of psi will decrease mileage by mpg OC. Increasing the tire pressure by one psi and maintaining a speed of mph will increase mileage by mpg OD. Increasing the speed by one mph and maintaining a tire pressure of pol will increase mileage by mpg E. Increasing the upood by one mph and maintaining a tire pressure of psl will increase mileage by mpg

Answer 1

Page M (x,y) = 56+0.2x -0.8y gives mileage (in mpg) X → pressure of the tire (in psi) y speed (in mph) MC36,42): replace x by 36 and y by 42 MC36142) 56 +0.2(36) - 0.8 ( 42) = 56 + 7.2-336 M (36,42) = (2916)[mpg mileage can mpg) Con miles per gallon) A Mileage is 29.6mpg at a tire pressure of (36 psi and a speed of (42 mph [at a tire pressure of 36 psi and a speed of 42 miles per hour, new cars mileage will be 29.6 mpg]
