Question

The normal body temperature of a camel is 37°C. This temperature varies by up to 3°C throughout the day. Write and solve an absolute value inequality that represents the range of normal body temperatures (in degrees Celsius) of a camel throughout the day.

Answer 1

The inequality is |T-37|≤3 and from 34 C to 40 C

Explanation:

Answer 2

The normal body temperature : to = 37° C
An inequality is:
| t - to | ≤ 3
| t - 37 | ≤ 3
t - 37 ≤ 3 AND ( - t - 37 ) ≤ 3
t ≤ 3 + 37 - t + 37 ≤ 3
t ≤ 40 - t ≤ 3 - 37
- t ≤ - 34 / *( - 1 )
t ≥ 34
Answer t ∈ [ 34°C, 40° C ].
