We have to determine,
Which expression represents the increase in temperature?
According to the question,
At midnight, the temperature was -8° F.
At noon, the temperature was 23° F.
To determine the expression that represents the increase in temperature calculation must be done in a single unit following all the steps given below.
Therefore,
The expression represents the increase in temperature is,
After an increase in the temperature, the value of temperature in noon is -23° F.
[tex]\rm The \ increase \ in \ temperature=|-8 + (-23) |\\\\The \ increase \ in \ temperature= |-8-23| \\[/tex]
Hence, The expression represents the increase in temperature is [tex]|-8-23|[/tex] .
