Answer:
2/5
Step-by-step explanation:
The general formula for the distance between two points is

Anyway, if A and B have the same x or y coordinates, this formula can be simplified. For example, in this case the two points have the same x coordinate of -8, so the following part of the formula simplifies:

So, we're left with

but the square root of a square is the absolute value of the object being squared:

which is this case means 
which is the correct length of the side.
Answer:
y=-9x+193
Step-by-step explanation:
Its decreasing by 9, and 175+(9x2) is 193
To solve this, I would just find what two adult tickets and one child ticket wold be worth.
To find that, just do:
5.20 + 9.90 * 2, which makes 25.
So now you just find how many 25s are in 900, or 36.
So 36 children's tickets were sold that day.
Hope I helped :)
Answer:
3rd option
Step-by-step explanation:
- 10 ≥ 6x - 4 ( add 4 to both sides )
- 6 ≥ 6x , then
6x ≤ - 6 ( divide both sides by 6 )
x ≤ - 1
Thus x = - 1 is a solution to the inequality
