Point A is at (-5, -4) and point M is at (0, -3.5).
Point M is the midpoint of point
and point B.
What are the coordinates of point B?

The coordinates of point B are (5,-3)

Step-by-step explanation:

we know that

The formula to calculate the midpoint between two points is equal to

In this problem

Point A is at (-5, -4) and point M is at (0, -3.5)

substitute in the formula

so

Solve for x_2

Solve for y_2

therefore

The coordinates of point B are (5,-3)

-1/2 +2

step-by-step explanation:

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
