Answer:
The temperature can vary from -5°F to 1°F on the freezer
Step-by-step explanation:
Inequalities
Let t be the temperature in degrees Fahrenheit. It was originally set to -2°F. The variation of the temperature throughout the day can be calculated as:
variation=t-(-2)=t+2
We know the temperature can vary by up to 3°F. Since the variation can be positive or negative, we must take the absolute value to comply with the restriction, that is:
[tex]|t+2|\le 3[/tex]
That is the inequality that represents the situation of the question. Now let's solve it.
The condition placed can be fulfilled only if
[tex]t+2\le 3[/tex]
And:
[tex]t+2\ge -3[/tex]
Solving the first inequality:
[tex]t\le 1[/tex]
And the second:
[tex]t\ge -5[/tex]
This means the temperature can vary from -5°F to 1°F on the freezer
