Asafety regulation states that the height h of a guardrail should be 106 centimeters with an absolute deviation of no more than 7 centimeters. write and solve an absolute value inequality that represents the acceptable heights of a guardrail. the absolute value inequality is_ . the acceptable range of heights of a guardrail are _cm to _cm.

The height h of a guardrail = 106 centimeters

absolute deviation =  7 centimeters

To find the acceptable heights of a guardrail , we add and subtract absolute deviation(7) from the mean height(106)

The acceptable range of height is 7 cm away from 106 to the left and then to the right.

106 + 7 = 113

106 - 7 = 99

acceptable heights are defined by

99 <=h<=113

The absolute value inequality is |x-106|<=7

The acceptable range of heights of a guardrail are 99 cm to 113 cm.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
