River C is 400 miles longer than river D. If the sum of their lengths is 5,600 miles, what is tge length of each river?

River C: 2,600 miles

River D: 3,000

Step-by-step explanation:

Since beside a 400 mile difference they are the same just subtract 400 and divide it by 2 then add 400 to find river d

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
