Question

IDK WHAT TO DO SOMEONE PLEASE EXPLAIN OR HELP
1. Points A and B are to be mapped onto a number line according to two equations. The solution to the equation 3x – 6 = 9 is the coordinate of point A. The solution to the equation 2x + 18 = -2 is the coordinate of point B.
(a) Solve the first equation to find the coordinate of point A. Show your work. (5pts)
(b) Solve the second equation to find the coordinate of point B. Show your work. (5pts)
(c) Determine the distance between points A and B. Explain. ( 5pts)

Answer 1

Alright so, let’s break this down.

To find the first coordinate you need to solve the first equation

To do that you can do
6+9=15
So that mean 3x has to be equal to 15
You divide 15 by 3

The answer to that is the solution to the first equation, or the first coordinate.

For the second one, you know x has to be negative because the solution is negative

2x is going to have to equal -20
-20/2 gets you the solution

Remember that it will be negative
You now have both of the coordinates

You take coordinate A and technically add coordinate B to it
You do that because B is negative and A is positive
Then you have the answer to c
