Say you go kayaking over a 2 mile stretch of river. The river is flowing at a speed of 1mph. You go 2 miles upstream, and then 2 miles downstream, back to your starting point, for one round trip. Make a function for it, then give me the graph of this function. Use a share link from Desmos, or upload a picture, or scan the graph you made on a piece of paper. Remember to show all vertical asymptotes and any horizontal asymptote.

4 mph

Step-by-step explanation:

Givens

Current = c = 2 mph

Alberta = r = ?

d = 2 mph upstream

d1 = 6 mph downstream

Formula

d = r * t

The time is the same so the formula becomes d/r = t

2/(r  - 2) = 6/(r + 2)    

Solution

Cross Multiply

2*(r + 2) = 6*(r - 2)

2r + 4 = 6r - 12                      Subtract 2r from both sides

4 = 6r - 2r - 12                       Combine the right.

4 = 4r - 12                             Add 12 to both sides.

4 + 12 = 4r

16 = 4r                                  Divide by 4

16/4 = 4r/4

r = 4

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
