Answer:
- Graph A: neither an Euler path nor an Euler circuit
- Graph B: both an Euler path and an Euler circuit
- Graph C: both an Euler path and an Euler circuit
Step-by-step explanation:
A non-directed graph will have an Euler circuit if all vertices have even degree. It will have an Euler path if it has an Euler circuit or if it has two vertices with odd degree (where the path can start and end).
<u>Graph A</u>
4 of the 5 vertices have odd degree. No Euler path, no Euler circuit.
<u>Graph B</u>
All 6 vertices have degree 4. This graph has an Euler path and an Euler circuit.
<u>Graph C</u>
5 of 6 vertices have degree 4, the remaining one has degree 2. This graph has an Euler path and an Euler circuit.
Sorry if i didn't get it right but i couldn't really tell where the two solutions seperate so....
10+y=5x+x2
y=6x-10
and
5x+y=1
y=5x+1
C = 25 because the amount of broth doesn't change
d = 60 because you add the total before to the new total
Answer:
The answer is k = 4.
Step-by-step explanation:
Given:
Y = 8 and X = 2.
Now, to solve direct variation.
direct with .
Now, using equation to solve direct variation:
Dividing both sides by 2 we get:
.
Therefore, the answer is k = 4.
