Step-by-step explanation:
Mean= 13.4
Median= 13
Range= 11
The system of equations representing the number of Blue-ray discs and DVD's after t months are:
507 + 26t
925 - 12t
Each month, the number of DVD's sold decreases by 12, this can be modelled as:
number of DVD in opening month - (monthly decrease x number of months)
Number of DVD's in t months = 925 - 12t
Each month, the number of Blue-ray discs sold increases by 26, this can be modelled as:
number of blue-ray discs in opening month + (monthly increase x number of months)
Number of Blue-ray discs in t months = 507 + 26t

First we need to find the slope of the given line. And for that we need to bring the equation in y=mx +b form where m is the slope. And for that, we need to solve the given equation for y.
0.5x-5y=9
Moving 9 to the left side
0.5x-5y-9=0
Moving 5y to the right side
0.5x -9 = 5y
Getting rid of 5 by dividing both sides by 5, that is
0.1x -(9/5)=y
or y=0.1x -(9/5)
Therefore slope of the given line is 0.1 and parallel lines have same slopes. Therefore slope of the parallel line is 0.1 too .
