Answer:
C.
There is no repeated x or y values
We know that a relation is a function, when each input of x value gives exactly one output of y-value.
In a function two or more x-coordinates can give same y-value, but one x-value cannot give two y-values.
We can see that in our given set each x-value corresponds to exactly one y-value, therefore, the given set represents a function.

Answer:
Your friend is kayaking faster.
Step-by-step explanation:
The way to approach this answer is by putting one of them in terms of the other. So that both are in terms of the same time. If you kayak 63 feet in 12 seconds how many feet do you kayak in 2 seconds? Simply divide by 6. 63/6 = 12/6. So, in 2 seconds (12/2) you kayak 10.5 feet (63/6). But your friend kayaks 21 feet in the same time... so he's going faster.
The answer for this problem would be 213
I believe the price for one box with the coupon will be $3.15. This is because 4.50 * .30 = 1.35
4.50 - 1.35 = 3.15 Thus the discounted price will be $3.15
B - 8 = 5
------ ---
b + 9 2
Cross Multiply
2(b-8)=5(b+9)
distribute
2b -16 = 5b + 45
subtract 5b from both sides
-3b - 16 = 45
add 16 to both sides
-3b = 61
divide both sides by -3
b = -61/3 or -20 1/3
