Determine the midpoint of segment AB when Al-7, 10) and B(13,-4).

(3, 3)

Step-by-step explanation:

In general midpoint (x, y) of a line segment AB with A( ) and B()

is  

The mid point of AB in our case where A(-7, 10) and B(13,-4).

x coordinate  is at ( -7+13)/2 = 6/2 = 3

y coordinate is at (10+ -4)/2 = 6/2 = 3

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
