The average operating temperature for a small water-cooled riding lawn mower engine is 220 °F with an absolute error of 20 °F. Which absolute value equation gives the minimum and maximum operating temperatures for the engine?

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
