Answer:
non- function
Step-by-step explanation:
any X being REPEATED (the first number of each pair) is non-function.
The answer is 12.3 hours.
On the way to the beach, the family averaged 58 mi/h over 377 mi, so we take 377/58 to find the amount of time spent going to the beach. 377/58 = 6.5 hours.
On the way back, they averaged 65 mi/h over the same 377 mi, so we take 377/65. 377/65 = 5.8 hours.
6.5 + 5.8 = 12.3
Just add the two equations.
8x-3y=22
I hope this helps :)
