If you consume less energy you pay less with respect to the amount of energy you saved. If you saved 16% of total energy you should expect to lower your bill by 16%. Count how much is left -> 1900-1900*0.16=1596$
Answer:

Step-by-step explanation:
The given system is
2x-y=4
x-y=-2
We write the system in slope-intercept form:
y=2x-4
y=x+2
The first equation has slope of 2 and y-intercept at (0,-4)
When y=0, x=2.
We plot (0,-4) and (2,0) to graph this first equation.
The second equation has a slope of 1 and a y-intercept at (0,2)
Also when y=0, x=-2.
We plot (0,2) and (-2,0) and draw a straight line through them.
The graph of the system is shown in the attachment.

Imagine two of the as squares and then have them
Answer:
The range would be increased by 2
3,5,5,5,6
The range for that set would be 3.
If 8 were added... 3,5,5,5,6,8
The range for that set would be 5.
A. > because 1/2 is more than 2/5
1/2 = 0.5
2/5 = 0.4
