Answer:
The coordinates of Y are (2,-0.2)
Step-by-step explanation:
Let the coordinates of Y be (x,y)
Since M is the midpoint of XY, so
Multiply both sides by 2
Cancel out the 2's from the top and bottom on the right side
Add 1 to both sides
Cancel out -1 and +1 on the right side
Flip the sides
Similarly,
Multiply both sides by 2
Cancel out the 2's on the top and bottom of the right side
Add 3 to both sides
Cancel out -3 and +3 on the right side
Flip the sides
So, the coordinates of Y are (2,-0.2)
Answer:
b=2r+4
Step-by-step explanation:
I don't think that you can do this using only one variable because there are two unknown amounts. Blue (b) is Red (r) multiplied by 2 plus 4 more, so the expression is b=2r+4.

Step-by-step explanation:
if you have one ball and then take away one ball, you will have zero balls
Answer:
39
Step-by-step explanation:
Alll the sides equal each other because of that curve u see at each angle, that curve means that the angles are the same, having the same angles means same sides, so just pick two equations to do this:
21 - x = 2x -3
add 3 to both sides
24 - x = 2x
add x to both sides
24 = 3x
divide by 3
8 = x
Now input 7 into the equations:
21 - x = 21 - 8 = 13
2(8) - 3 = 16 - 3 = 13
x + 5 = 8 + 5 = 13
Now add: 13 + 13 + 13 = 26 + 13 = 39
Another way for u to save time is remember how i said all the sides were the same? you could just solve one equation, so it'll be 13 and multiply that with 3 to get the perimeter since ur adding 13 three times anyway
So just a simple: 13(3) = 39
