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:

|x − 98.6| ≥ 2

Step-by-step explanation:

Answer 2

Answer:

$x\geq100.6$ and $x\leq 96.6$

Step-by-step explanation:

It is given that the normal body temperature is $98.6^\circ F$.

A temperature 'x' that differs from normal by at least $2^\circ F$ is considered unhealthy. So the inequality to represent such situation is,

$\left | x-98.6 \right |\geq 2$

It can be further written as,

$x-98.6\geq 2$ and $x-98.6\leq -2$

$x\geq (98.6+2)$ and $x \leq(-2+98.6)$

$x\geq100.6$ and $x\leq 96.6$

So the inequality to represent such condition is $x\geq100.6$ and $x\leq 96.6$ .
