the heat in the house is set to keep the minimum and maximum temperatures (in degrees fahrenheit) according to the equation |x - 72.5| = 4. what are the minimum and maximum temperatures in the house?\no 72.5°f and 76.5°f\no 68.5°f and 76.5°f\no 70.5°f and 74.5°f\no 72.5°f and 74.5°f

Answer

Explanation:

Step1: Recall absolute - value property

If (|a| = b) ((b\geq0)), then (a = b) or (a=-b). So for (|x - 72.5| = 4), we have (x-72.5 = 4) or (x - 72.5=-4).

Step2: Solve (x-72.5 = 4)

Add 72.5 to both sides of the equation: (x=4 + 72.5=76.5).

Step3: Solve (x - 72.5=-4)

Add 72.5 to both sides of the equation: (x=-4 + 72.5 = 68.5).

Answer:

68.5°F and 76.5°F
