The difference between 8 and n looks like,
8 - n
No this is not a function because it is not one to one! Each x value needs to have only one output! The -2 values have two different outputs thus making it not a function.

Answer:
- 28 general admission
- 26 student
Step-by-step explanation:
Let g represent the number of general admission tickets sold. Then the revenue is ...
3g +2.50(54-g) = 149
.50g = 14 . . . . . . . . . . . subtract 135
g = 14/.5 = 28 . . general admission tickets sold
54-g = 26 . . . . . student tickets sold
Answer: <em>x</em> = 20
Step-by-step explanation:
If line <em>m</em> is parallel to line <em>n</em>, the two angles given will be congruent because they will be alternate exterior angles (which are congruent).
This means we will set them equal to each other and solve for <em>x</em>.
Given:
(4<em>x</em> - 23) = (2<em>x</em> + 17)
Add 23 to both sides of the equation:
4<em>x</em> = 2<em>x</em> + 40
Subtract 2<em>x</em> from both sides of the equation:
2<em>x</em> = 40
Divide both sides of the equation by 2:
<em>x</em> = 20
