Answer: a. 45 = k
b. d/t = 45
c. d = 45t
<u>Step-by-step explanation:</u>
The constant of proportionality (k) equals y divided by x if it is a direct variation. In the given problem, y is represented by distance (d) and x is represented by time (t).

Answer:
Step-by-step explanation:
<u>Given</u>
<u>To find</u>
<u>Solution</u>
- P(x) = 0
- cx + c = 0
- cx = -c
- x = -c/c
- x = -1
The answer is X=27 degrees
