It does represent a direct variation.
Direct variation: y = kx
y varies directly with x
Your equation 2y = 5x + 1 is in the form of y = kx but we need to divide out the 2 from 2y so we have the following
2y = 5x + 1
2y / 2 = 5 x/ 2 + 1/2
y = 5x / 2 + 1/2
y = kx
k = 5/2
k = constant of variation = 5/2
Answer:
We have the equation A*C = A
Now, as both sides of the equality are the same thing, we can do the same operation to both sides and the equality will remain true.
We can divide both sides by A and get:
(A*C)/A = A/A
C = 1
So here we finded the value of A.
If A and C are matrices, then C is the identity matrix.
Answer: Gavin was faster because his time was less than Crystal's.
Step-by-step explanation: They rollerbladed the same distance but Gavin did it in less time.
Hope this helped!

Train traveled 175 kilometers (86+89) in 7 hours (2+5).
speed = distance/time
speed = 175 / 7
speed = 25 kilometers / hour
