Answer:
The answer might be 100° c
Yours d+v=45minutes and roommate d+v=100minutes
Its max is 780
2/3 + 1/6 = 5/6
650/5=130
650+130=780
Answer:

Step-by-step explanation:

Apply formula:
and

We get:







Hence final answer is

In piecewise linear functions, the endpoint of one segment and the initial point of the next segment can have the same x-coordinate but a different value of f(x).
Such difference in values is called a step or discontinuity and such a function is called a discontinuous function.
Here in this case, there are 3 discontinuities: x=-3, x=3 and x = 5.
x = -3 because x is smaller than or greater than -3 but not equal.
x = 3 since greater than 3 in one of the inequalities.
x = 5 since x is smaller than 5 in one of the limits.
