Answer:
The correct answer is B. The number of rides and the total cost are both dependent variables, as both depend on the amount of money that Nia has.
Step-by-step explanation:
The total cost is dependent because it relies on how many rides Nia takes, and the $19.50 limit.
The number of rides is dependent on the limit of $19.50 because the $19.50 is the limit and the total amount of rides is locked by $19.50
I'm not sure, though.
-4(3r - 2) - 2(r + 1) = 0
-12r + 8 - 2r - 2 = 0
-14r + 6 = 0
-14r = - 6
r = 6/14
r = 3/7

Answer:
a = 0
Step-by-step explanation:
The cube root (radical) is equivalent to x^(1/3). When that is divided by x^(1/3), the result is ...
(x^(1/3))/(x^(1/3)) = x^(1/3 -1/3) = x^0
Comparing that to x^a, we find a=0.
