Answer:
$2 because the x axis is bags of candy 1 and the y axis is the cost 2 therefore 1 bag of candy cost $2 and 2 bags of candy cost $4
M<ABC = m<EBD = 36 (vertical angles)
78 - x + 36 + 3x - 10 = 180 (straight angle)
Now solve for x
78 - x + 36 + 3x - 10 = 180
2x + 68 = 180
- 68 -68 (subtract 68 on both sides)
2x = 58
x = 29
The answer of the question is 140. hope i help you ;)
The second table. A linear function is a function where adding the same amount to x should add the same amount to y.
In table 2, you can see that adding 1 to x adds 2 to y. All the other tables describe non-linear functions.
For

the function is undefined.

So, the limit doesn't exist.
