What methods could you use to calculate the x-coordinate of the midpoint of a horizontal segment with the endpoints of (-20, 0) and (20, . a. divide 0 by 20 . b. calculate the average of the x-coordinates . c. divide 20 by 2 . d. divide 2 by 20 . e. take the average of the endpoints .

Option B is correct .

Step-by-step explanation:

Consider the line segment joining points . It's midpoint is given by .

Midpoint is basically the centre point of a line segment .

Here, given points are .

Consider the following:

To find: x-coordinate of the midpoint of a horizontal segment with the endpoints .

Solution:

x-coordinate =

On putting , we get

x - coordinate =

So, here we calculate the average of x-coordinates .

Option B is correct .

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
