The coordinates of E are (5.75, 0).

<h3>What is midpoint?</h3>

The midpoint is the middle point of a line segment. It is equidistant from both endpoints, and it is the centroid both of the segment and of the endpoints.

Given that, C is the midpoint of AB, D is the midpoint of CB and E is the midpoint of DB.

Formula for coordinates of midpoint,

(x, y) = [(x1+x2)/2, (y1+y2)/2]

Coordinates of C;

(x, y) = (-10+8)/2, (14-2)/2

(x, y) = (-1, 6)

Coordinates of D;

(x, y) = (-1+8)/2, (6-2)/2

(x, y) = (3.5, 2)

Coordinates of E;

(x, y) = (3.5+8)/2, (2-2)/2

(x, y) =  (5.75, 0)

Hence, The coordinates of E are (5.75, 0).

WORTH ALL MY POINTS PLEASE HELP

Answer:

  (a)  = 7 +3·5

Step-by-step explanation:

The given expression evaluates to ...

  6 +2^4 = 6 +16 = 22

The offered choices evaluate to ...

  7 +3·5 = 7 +15 = 22

  4·10^3 +96 = 4·1000 +96 = 4096

  7^2 = 49

  3·10 +2 = 30 +2 = 32

The only choice that will form a proper equation is the expression that evaluates to 22:

  6 +2^4 = 7 +3·5
