The coordinates of point B is (6, -7), if the Point A is at (-6, 8) and point M is at (0, 0.5).
Step-by-step explanation:
The given is,
A (-6, 8)
M (0, 0.5)
Where, A is first point
M is mid point
Step:1
Formula for calculation of Mid point between two points,
........................(1)
Where,
A (-6, 8) - 
M ( 0, 0.5) - 
Substitute the values,
( 0, 0.5) = 
For x value,
0 = 
0 = -6 + 
= 6
For y values,
0.5 = 
1 = 8 + 
= -7
Result:
The coordinates of point B is (6, -7), if the Point A is at (-6, 8) and point M is at (0, 0.5).

I got it right on the Math assignment!
1 and a quarter pie for each family or 1.25
Answer:
3(x + 6) and 4x + 18 - x
Step-by-step explanation:
Let's solve each option to see whether we would get 3x + 18:
✔️2x + 9 + 2x + 9
Add like terms
2x + 2x + 9 + 9
4x + 18
✔️3(x + 6)
3*x + 3*6
3x + 18 (it is an equivalent)
✔️4x + 18 - x
Add like terms
4x - x + 18
3x + 18 (it is an equivalent)
✔️2(4x + 9)
8x + 18
Therefore, the expressions 3(x + 6) and 4x + 18 - x are equivalent to 3x + 18
