The slopes and linear equations are always not easy
Answer:
Step-by-step explanation:
These equations are both continuous for all values of x so their is no restriction upon the domain. Both have a domain of (-oo, +oo)
Answer:
The initial temperature was To = -14 degrees
Step-by-step explanation:
Solution:-
- We will take the starting temperature to be = Ti
- The final temperature, Tc = 16 degrees
- We are given that there is a drop of 10 degrees from initial temperature To. We can mathematically express this as:
To - 10
- Then there is a rise of 40 degrees after the drop of 10 degrees. The mathematical expression would be:
To - 10 + 40
- The current temperature is Tc. We can equate the expression developed to final temperature:
To - 10 + 40 = Tc
- Solve for To:
To = 16 - 40 + 10
To = -14 degrees
