Answer:
statement: 2. both pairs of parallel lines are congruent
reason: 2. def. of a parallelogram
and that should be all you need
Step-by-step explanation:
#34.
After a dilation of 2 (about the origin), all coordinates will be doubled.
Thus the image is 2 time the original matrix, or
-6 -4 -1
8 2 10
#37
a12 means the element on the first row, and the second element from the left.
The question does not indicate which matrix is named "a", but by elimination, we will assume it is the first matrix in the matrix equation.
Isolating the elements 12 (first row, second element) in the equation, we get
a12+5 = 1
which tells us that
a12=1-5 = -4

The mean
is
(the sum of the values of all the points)
divided by
(the
number of points).
There are 10 points on the graph.
Their 'A' values add up to 50.
The mean of the 'A' values is (50/10) = 5 .
