2. the temperature in degrees fahrenheit after h hours is given by t(h)=72 - 3h. what is the temperature after 4 hours?
Answer
Explanation:
Step1: Substitute h value
Substitute $h = 4$ into $T(h)=72 - 3h$. $T(4)=72-3\times4$
Step2: Calculate multiplication
First calculate $3\times4$. $3\times4 = 12$ So $T(4)=72 - 12$
Step3: Calculate subtraction
Calculate $72-12$. $72-12=60$
Answer:
60
