Answer:
Step-by-step explanation:
Number 5 is third option
and number 6 is second option
Answer:
0
Step-by-step explanation:
Isolate the variable x. First, distribute 3 to all terms within the parenthesis.
3(2x + 3) = 3(2x) + 3(3) = 6x + 9
6x + 9 = 9
Isolate the variable x. Note the equal sign, what you do to one side, you do to the other. First, subtract 9 from both sides.
6x + 9 (-9) = 9 (-9)
6x = 0
Divide 6 from both sides.
(6x)/6 = (0)/6
x = 0
0 is your answer.

x=8+sqrt-8/12, x=8-sqrt-8/12
I think...
Answer:
Step-by-step explanation:
Split it into 2 inequalities:
-8 < y + 2x
y + 2x < 14
Isolate y , subtract 2x from first and then from second
-8 -2x < y
y < 14 -2x
Rewrite it so it looks pretty?
y > -2x-8
y < -2x +14
You can use the calculator to graph each inequality.
The solution or the system is the area where the 2 solutions for each line overlap.
