What are the coordinates of the midpoint between (3, -7) and (-5, 2)? (-2, -5) (-1, -2.5) (-4, -4.5) (1, 2.5)

(-1, -2.5)

Step-by-step explanation:

add 3 to -5 to get -2. divide it by 2 to get -1. this is your x value. add -7 to 2 to get -5 and divide by 2 to get -1.25. this is your y value

6 on both sides and twelve on the top and the bottom

step-by-step explanation:

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)
