Given a line segment that contains the points a, b, & c in order, if ab = x - 2, and bc = 2x + 6, and ac = 19, find x.
select one:
a. 9
b. 11
c. 15
d. 5

The answer to your question is: x = 5 units

Step-by-step explanation:

Data

AB = x - 2

BC = 2x + 6

AC = 19

x = ?

Process

                           AB + BC = AC

Solve for x,                        x - 2 + 2x + 6 = 19

                                           3x + 4 = 19

                                           3x = 19 - 4

                                           3x = 15

                                           x = 15 / 3

                                           x = 5 units

range is infinite on both x and y axis positive and negative

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
