on the freeway, it is unsafe to drive too slowly or too quickly. the safest driving speeds on the freeway near allans town were scientifically determined to be between the minimum and maximum speeds (in miles per hour) according to the equation |x - 55| = 4.2. which equation can be used to determine the maximum safe driving speed?\no x - 55 = 4.2\no x - 55 = -4.2\no x + 55 = 4.2\no x + 55 = -4.2

on the freeway, it is unsafe to drive too slowly or too quickly. the safest driving speeds on the freeway near allans town were scientifically determined to be between the minimum and maximum speeds (in miles per hour) according to the equation |x - 55| = 4.2. which equation can be used to determine the maximum safe driving speed?\no x - 55 = 4.2\no x - 55 = -4.2\no x + 55 = 4.2\no x + 55 = -4.2

Answer

Explanation:

Step1: Recall absolute - value property

The absolute - value equation (|a| = b) is equivalent to (a = b) or (a=-b). For the equation (|x - 55|=4.2), we have (x - 55 = 4.2) or (x - 55=-4.2).

Step2: Determine the maximum speed

When (x-55 = 4.2), solving for (x) gives (x=4.2 + 55=59.2). When (x - 55=-4.2), solving for (x) gives (x=-4.2 + 55 = 50.8). The larger value of (x) comes from the equation (x - 55 = 4.2).

Answer:

A. (x - 55 = 4.2)
