Humans have a normal body temperature of 98.6°F. A temperature, x, that differs from normal by at least 2°F is considered unheal
Alecsey [184]

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 .

Which expressions represent the distance between 4.7 and −11.2−11.2 on the number line?
Alexxx [7]
Two of them: the second and the fifth.

Distance is the absolute value of the difference of the two points:

|-11.2 - 4.7| = |-15.9| = 15.9

and |4.7 - (-11.2)| = |4.7 + 11.2| = |15.9| = 15.9
