When you solve this equation, you can plug in 2x + 10 for y, so you would have 2x + 10 = 2x +4. When you solve for x, you notice that you end up getting 10 = 4, which is impossible!
There are NO solutions for this, because 10 will never equal 4.
The slope of the first line is 2.
The slop of the second line is also 2.
The lines ARE parallel- they have the same slope!
They do not have the same y-intercept, one of them crosses at y=4, and the other crosses at y=10.
Since the lines are parallel, they will never cross, which is why there are no solutions for this equation.
Hope this helps! :)
I believe that it is true due to it, the distance formula uses x and y coordinates. So, they're the same thing in two different types, or so..

Answer: D) 8 hours
Step-by-step explanation:
Machine A: 840 an hour
Machine B: 760 an hour
h = hour
840 + 760 = 1600
In an hour, they can both sort 1600 mails.
1600h = 12800
Divide each side by 1600
h = 8
840 * 8 = 6720
760 * 8 = 6080
6720 + 6080 = 12,800
