Answer:

  (-12, -10)

Step-by-step explanation:

Midpoint M is the average of endpoints A and B:

  M = (A +B)/2

  2M = A + B . . . . . . multiply by 2; next, subtract A

  B = 2M - A . . . . . . the missing endpoint can be found this way

  B = 2(-8, 0) -(-4, 10) = (2(-8)+4, 2(0)-10) = (-12, -10)

Write an inequality for each graph.
Oksi-84 [34.3K]

x = unknown number (that is a solution/makes the inequality true)

When the inequality sign is </> (less than/greater than), the dot is an open circle.

When the inequality sign is ≤/≥ (less than or equal to/greater than or equal to), the dot is a closed circle.

14.) The line has an open circle on -8, and a closed circle on 11.

-8 < x ≤ 11   [x is any number greater than -8 and less than or equal to 11]

15.) The line has a closed circle on -14 and 5.

-14 ≤ x ≤ 5    [x is any number greater than or equal to -14 and less than or equal to 5]
