9. Solve the equation.<br> 4(6 – x) + 4 = 2 (3x + 1) – 6
sasho [114]

Answer:

x=3.2

Step-by-step explanation:

4(6 – x) + 4 = 2 (3x + 1) – 6

24 - 4x + 4 = 6x + 2 - 6

28 - 4x = 6x -4

-4x - 6x = - 4 - 28

-10x = - 32

divide both sides

x = 16/5 or x = 3.2

hope this helps :)

Simplify the expression. 5 (z+4)+5 (2-z)
Nadya [2.5K]
First, we're going to distribute both fives out, which gives us this:
5z + 20 + 10 - 5z
Then, we can combine the like terms. However, since they are opposites, they cancel out, which gives us:
20 + 10
This equals 30.
Hope this helps!

Triangle QRS is reflected over y = 2. What are the coordinates of Q'?
Levart [38]

Answer:

(1,6)

Step-by-step explanation:

In order to reflect a point over a horizontal line, you need to count how many units it takes to reach that line (going vertically). Once you have that number, count that many units starting from that point on the line (again, going vertically), then that is your reflected point.

Counting from point Q to the line y = 2, it takes 4 units. So starting from that point on the line where I left off, I would count another 4 units, taking me to (1,6). The picture below explains it better visually.
