Question

Humans have a normal body temperature of 98.6 F A temperature, x, that differs from normal by at least 2°F is considered unhealthy. Which inequality could be used to determine whether a temperature is unhealthy?

Answer 1

Answer: 98.6 - x ≥ 2 or x - 98.6 ≥ 2  

Step-by-step explanation:

Since, the normal temperature = 98.6° F

Also, the temperature that differs from normal by at least 2°F is considered unhealthy.

If the temperature is x degree F,

Then, we have two conditions,

Condition 1 : x > 98.6,

The difference between 98.6 and x = x - 98.6

Then the inequality be,

x - 98.6 ≥ 2

Condition 2 : x < 98.6

The difference between 98.6 and x = 98.6 - x

Then the inequality be,

98.6 - x ≥ 2
