Answer:
graph 1
Step-by-step explanation:
Let's look at graph 1:
The first vertex (the left hand top corner) has a degree 3 because there are 3 line segments coming from it.
Let's check to see if the other vertices have degree 3.
The second vertex (the middle top) has degree 3 because again it has 3 line segments coming from it.
The third vertex (the top right) has degree 3 because it has 3 line segments coming from it.
The fourth vertex (the bottom left) has degree 3 because it has 3 line segments coming from it.
The fifth vertex (the middle bottom) has degree 3 because it has 3 line segments coming from it.
The last vertex (the bottom right) has degree 3 because it has 3 line segments coming from it.
Let's look at graph 2:
The first vertex (top left) has degree 1 because it has one line segment coming from it.
The second vertex( middle top) has degree 2 because it has 2 line segments coming from it.
Graph 2 doesn't have the same degree per vertex.
Looking at graph 3:
The first vertex (top left) has degree 1 while the second (top middle) has degree 2.
Graph 3 doesn't have the same degree per vertex.
Looking at graph 4:
The top left has degree 1. Looking at one of the middle vertices there, they have degree 4 each because they have 4 line segments coming from it. So graph 4 doesn't have the same degree per vertex.
The answer is only graph 1.

Answer:
7
Step-by-step explanation:
There are 7 days in a week, and she sent 49 messages by the end of the week. Assuming that she sent the same number of messages each day, we would take the number of messages and divide it by the number of days, 49 and 7. 49 divided by 7 is 7. She sent 7 messages each day!
Hope this helps, brainliest always appreciated haha
