One winter day, the temperature was between –14°F and –3°F. Which inequality represents the range of temperatures, t, during that day?
-14 <= t <= -3
or,
|t+8.5| <= 5.5
What are your choices?
To represent the range of temperatures, t, during that day, we need to determine the minimum and maximum possible temperature values. In this case, the minimum temperature is –14°F and the maximum temperature is –3°F.
Therefore, to represent the range of temperatures, we use the inequality:
-14°F ≤ t ≤ -3°F
