1 answer:
pychu [463]3 years ago
4 0

Answer:

It's hard to tell if they're dotted lines or not. If your inequality sign doesn't have a line under it then it is going to be a dotted line. If your sign is facing like this < then your shading will always be below the line graphed and if the line is facing > then it will always be shaded above the line graphed.

It's either the first picture or the second picture, but it's hard to tell with the lines provided

What is the value of x for the given equation? 4-2(X +7) =3 ( X +5)
ryzh [129]

Answer:

Step-by-step explanation:

4 - 2(x + 7) = 3(x + 5)                  Remove the brackets.

4 - 2x - 14 = 3x + 15                    Combine

-2x- 10 = 3x + 15                         Add 2x to both sides

- 10 = 2x + 3x + 15                      Combine

-10 = 5x + 15                               Subtract 15 from both sides

-10 - 15 = 5x                                Combine the left side      

-25 = 5x                                       Divide by 5

-25/5 = 5x/5

x = - 5
