Answer: Choice A) There must be a vertical asymptote at x = c
Explanation:
The first limit 
 says that as x approaches c from the left side, the f(x) or y values approach negative infinity. So the graph goes down forever as x approaches this c value from the left side.
The limit 
 means that as x approaches c from the right side, the y values head off to positive infinity. 
Either of these facts are enough to conclude that we have a vertical asymptote at x = c. We can think of it like an electric fence in which we can get closer to, but not actually touch it.
 
        
             
        
        
        
ABC has
A as the first letter
B as the second letter
C as the third letter
The order is important
Similarly with EFG we hae
E as the first letter
F as the second letter
G as the third letter
The order is also important
Based on the orderings, we can say
A corresponds to E
B corresponds to F
C corresponds to G
Which means
A rotates to E
B rotates to F
C rotates to G
The final answer is choice C) Angle C
since we're looking for the angle that rotates or maps to angle G
        
             
        
        
        
Answer:
C
Step-by-step explanation:
The lines mean the distance away from 0. When i say lines, I mean the two "l" that accompany the numbers. I forgot what there called (good job me). 
Since we want to know how far apart they are, we need to add them. 
 
        
                    
             
        
        
        
Answer:
 
Step-by-step explanation:
As given
if n erasers have a weight of 80 grams .
I.e
n erasera =  80 grams.
1 erasers weight .

Now find out the weight of the 50 erasers.

Simplify the above
