Answer:
-2x +8
Step-by-step explanation:
The terms involving x are "like" terms, so their coefficients are added when the terms are combined.
= 32x -34x +8
= (32 -34)x +8 . . . . . x is factored out according to the distributive property
= -2x +8

Let's assume that a month has four weeks.
If William made 400 miles by travelling only on Saturdays and Sundays and there were 4 weekends during the month, then he travels 400 / 4 = 100 miles during a weekend, which is 100 / 2 = 50 miles a day.
If Jason travels every weekday during the month and he does 500 miles, then he travels 500 / 20 = 25 miles a day.
It means that William travels more miles per day.
Answer:
D. y = { -x + 2 x ≥ 1}
{ x + 1 x < 1}
Step-by-step explanation:
First is to eliminate A and C, why?
This is because of the end points shown on the graph.
As shown, if you look at the point of (2,1) it is black, this means that not only is it closed but it is also means ≤ or ≥ symbol.
You are now left with B and D
The difference between these two is the symbols; they are facing the opposite directions.
While B says x ≤ 1, and x > 1
While D says x ≥ 1, and x < 1
The direction of the symbols depends on the direction of the lines and what is part of it (some what like a shaded area)
So you answer would be D
