Answer:
The answer is option 2.
Step-by-step explanation:
In the question, the independent variable is time and dependent is distance. As the time changes, the distance will also change it means the distance depends on time.
For example,
Let t = 1,
Let t = 5,
Therfore, as time increases, distance will also increase.

Answer: c = 29</h3>
Work Shown:
Use the pythagorean theorem
a^2+b^2 = c^2
21^2 + 20^2 = c^2
441 + 400 = c^2
841 = c^2
c^2 = 841
c = sqrt(841)
c = 29
Answer:
I cant see it so can u do something so i can see it plz
Y - 3x = 7 . . . . . . . . (1)
21 + 9x = 3y . . . . . .(2)
From (1), y = 3x + 7
substituting for y into (2), we have
21 + 9x = 3(3x + 7) = 9x + 21
0 = 0
Therefore, the system has an infinte number of solutions.
