33) When adding matrices, just add the numbers that are in the same spot. In this problem we are given A and C, and we are asked to find B if A + B = C
So B = C - A

34) When multiplying matrices, the number of columns in the first matrix needs to be the same as the number of rows in the second matrix. Then the outcome will have the same number of rows as the first matrix and same number of columns as the second matrix. In this case, the result will be a 2x2.

Answer:
y = 1
Step-by-step explanation:
The line of reflection will be a parallel line midway between y = - 3 and y = 5
y = =
= 1
line of reflection is y = 1
