Answer:
1/13 I think but I'm not sure wait it's wrong
Step-by-step explanation:
add all the pupils who play a instrument which is 20 so u do 33-20=13
Answer & Step-by-step explanation:
In order to solve this problem, it's important that we look at the tiles and the the signs that are in front of them. The top row of tiles represents our first expression and the bottom row of tiles represents our second equation.
The two large tiles are positive so they are going to be positive in our equation.
(x² ) - (-x² )
The four blue rectangle tiles are also positive, so they are going to be positive in our equation. The two red rectangle tiles are negative, so they are going to be negative in out equation.
(x² + 4x) - (-x² + 2x)
The two red square tiles are negative, so they are going to be negative in our equation. The four blue square tiles are positive, so they are going to be positive in our equation.
(x² + 4x - 2) - (-x² + 2x - 4)
So, your answer is going to be letter choice C.
The answer is 6km
6km is the greatest

Answer: -1</h3>
=======================================================
Explanation:
First we need to find the slope of this given line.
The two points on here are (0,-3) and (3,0)
Apply the slope formula
m = (y2-y1)/(x2 - x1)
m = (0-(-3))/(3-0)
m = (0+3)/(3-0)
m = 3/3
m = 1
The slope of the given line is 1. The negative reciprocal of this is -1, which is the perpendicular slope.
Side Note: Any two perpendicular lines always have their slope multiply to -1, as long as neither line is vertical.
