Answer:
A=5t+12
B=6t+6
At 6 hours, both equations equal $42.
The correct answer is 30 degrees.
Answer:
We know that the sum of the degrees of the vertices of the graph is twice the number of edges of the graph.
Let
be a graph with vertices 
Then
where
is the number of edges of the graph. Since the graph is regular of degree r then all vertices have degree r. Thus,

To answer the question above, make use of one of the definitions of the inverse functions. If h(x) and f(x) are inverses of each other, then applying the operation, h(f(x)) will give back the value of the initial value. Therefore, the answer is x.
