1. ## Body Temperature

Normal human body temperature is 98.6° F. A temperature x that differs from normal by at least 1.5° F is considered unhealthy. A formula that describes this is
|x - 98.6| ≥ 1.5 is given.

A. Show that a temperature of 97°F is unhealthy.
B. Show that a temperature of 100°F is NOT unhealthy.

Question:

Must I tackle this problem similar to the Foreign Household Voltage question posted the other day?

A. Show that a temperature of 97°F is unhealthy.

Let x = 97

|97 - 98.6| ≥ 1.5

|-1.6| ≥ 1.5

1.6 ≥ 1.5

Unhealthy temperature.

B. Show that a temperature of 100°F is NOT unhealthy.

Let x = 100

|x - 98.6| ≥ 1.5

|100 - 98.6| ≥ 1.5

|1.4| ≥ 1.5

1.4 IS NOT greater than or equal to 1.5.

Temperature is NOT unhealthy.
