Answer:
16,20,28
Step-by-step explanation:
64 /(4+5+7)
64/16= 4
sides of triangle=4×4 :5×4: 7×4
=16:20:28
A- 10.5
B- 5.25
is what the answers are
Yeah. You basically have to look at every x value and see if for every x value, is there ONLY one y-value. So in your example, it is a function because every x value has only one y value. Let’s say you had (1,3) and (1,5). That would not be a function because the x value of 1 has TWO y values (3 and 5), therefore it is not a function.
That’s how you can easily spot if something is a function by just looking at a handful of ordered pairs. I hope this makes sense.
The answer would be B. 3 gallons per minutes.
