The y int is where the line crosses the y axis...it is (0,1)...or just 1
1 minute, the number of minutes students stretch when they do not jog
Answer:
No
Step-by-step explanation:
Reason for this is because when you divide 4 into 83,391,946 it ends up as 20847986.5 and since the number has to be whole its not divisible
The domain is all x-values of coordinate pairs.
But, if you need a reasonable domain for a graph, it should be all integers (whole numbers) greater than or equal to zero.
This is because you can’t have 1/2 of a person or 1/2 of an engine. You also can’t have any negative engines either. Therefore, the domain would need to be whole numbers greater than (or equal to 0).
We are going to denote the number of additional minutes with

, and the total cost of the call with

.
From PONCO, we know that they charge $1.25 for the first minute, and $0.30 for each additional minute; knowing that our additional minute is

and our total cost of the call is

, we can set up an equation to relate the values:

we are going to call this equation (1)
From CowBell, we know that they charge 1.40 for the first minute, and $0.25 for each additional minute. so just like before we can set up an equation to relate the values:

We are going to call this equation (2)
Since the total cost

of equations (1) and (2) is the same, we can equate them to find

:




We can conclude that after 3 additional minutes the cost of the calls will be the same; therefore, the correct answer is
B.
