Answer:
In graph theory and computer science, an adjacency matrix is a square matrix used to represent a finite graph. The elements of the matrix indicate whether pairs of vertices are adjacent or not in the graph.
In the special case of a finite simple graph, the adjacency matrix is a (0,1)-matrix with zeros on its diagonal. If the graph is undirected, the adjacency matrix is symmetric. The relationship between a graph and the eigenvalues and eigenvectors of its adjacency matrix is studied in spectral graph theory.
The adjacency matrix should be distinguished from the incidence matrix for a graph, a different matrix representation whose elements indicate whether vertex–edge pairs are incident or not, and degree matrix which contains information about the degree of each vertex.

Step-by-step explanation:
Find attached the first sum.
x denotes horizontal and y denotes vertical
When the value of x is positive, it moves to right side and when x is negative, it moves left sides 'x unit'
When the value of y is positive, it moves to up side and when y is negative, it moves down sides 'y unit'

Answer:
Hello,
16
Step-by-step explanation:
2 x 1 = 2
2 x 2 = 4
2 x 4 = 8
2 x 8 = 16
2/1 = 4/2 = 8/4 = 16/8 = 2
First find the difference that went by subtracting the 2 numbers:
340 - 306 = 34
divide that by the number of students that went to the first dance:
34 / 340 = 0.1 = 10% decrease
