B
Step-by-step explanation:
Hello!
You look at the table and see what graph matches the data
0-4 = 5
We look for the graphs that of 0-4 at 5
That gives us B or C
We look at the next values
5-9 = 10
We look for the graph that has 5-9 equal to 10
That gives us the answer of B
The answer is B
Hope this helps!
3x is the miles from downstream
4 (x - 1) is the return trip
Solution:
3x = 4 (x - 1)
3x =4x - 4
-x = -4
x = 4
The outward journey 3x = 12 miles
Return journey is same length
Therefore the distance travel is 24 miles

Answer: In June 2097
Step-by-step explanation:
According to the model, to find how many years t should take for 
we must solve the equation 
. Substracting 21100 from both sides, this equation is equivalent to 
.
Using the quadratic formula, the solutions are 
and 
. The solution 
can be neglected as the time t is a nonnegative number, therefore 
.
The value of t is approximately 85 and a half years and the initial time of this model is the January 1, 2012. Adding 85 years to the initial time gives the date January 2097, and finally adding the remaining half year (six months) we conclude that the date is June 2097.
