Answer:.
increasing from negative infinity to -2, decreasing from -2to 2, constant from 2 to 4 and increasing from 4 to positive infinity. A graph always increases and decreases over x axis and you show x points.
Step-by-step explanation:
Solve the equation. Isolate the variable, x.
Note the equal sign, what you do to one side, you do to the other.
First, subtract 8 and 10x from both sides:
2x (-10x) + 8 (-8) = 12 (-8) + 10x (-10x)
2x - 10x = 12 - 8
Simplify. Combine like terms:
(2x - 10x) = (12 - 8)
-8x = 4
Isolate the variable, x. Divide -8 from both sides:
(-8x)/-8 = (4)/-8
x = -(4/8)
Simplify:
x = -1/2
-1/2 is your answer for x.

Answer:
Step-by-step explanation:
At the self employed store, her monthly expense would be
y = $835
Which would plot as a horizontal line
At the franchise store here expense would be
y = 5x where x is the number of haircuts completed.
This would plot as a straight line of slope 5
The two would intersect when the two y values are equal
5 x = 835
so the same cost per month would occur at y = 835
at the franchise, she would have completed 835/5 = 167 haircuts.
If she plans on doing fewer than 167 haircuts per month, she nets more money at the franchise,
If she completes more than 167 haircuts per month, the self employed store deal keeps more money in her pocket.
