The answer is no. Because solution (a,b) means x=a, y=b.and we have a-b=5. And (b,a) would mean x=b and y=a but then x-y=b-a=-(a-b)=-5≠5. So the pair (b,a) is not a solution.
Here you go the answer is 32.5 gallons by each car. Hope that helped!

Hello from MrBillDoesMath!
Answer:
Choice B
Discussion:
The answer shown highlighted is the correct answer
For a function, each value in the domain should be assigned a unique value in the range. In the case of ordered pairs, each x value in an order pair should have a unique y value. This aspect fails for Choices A, C, and D. Details follow.
Choice A: Not a function because (3,3), and (3,2) both have x = 3 but associated y value is not unique (equal 3 or 2)
Choice C: Not a function because (1,-1) and (1, -2) both have x = 1 but associated y value is not unique (equals -1 or -2)
Choice D: Not a function because (2,3) and (2,1) both have x= 2 but associated y value is not unique (equals 3 or 1)
Choice B has no such issues as an x value is repeated.
Thank you,
MrB
