5. A new car is equipped with three fuel saving devices. Device A, by itself, saves 25% on fuel, device B by itself, saves 45% on fuel, and device C by itself saves 30% on fuel. Now, suppose that the three devices are used together, and that they act independently. Will the combination save 25+45+30=100 percent on fuel? Probably not. What is the correct answer?

40% off the regular price is the correct answer.

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

answer: (3,11) is your answer.
