The answer should be A. For example, if x = 1, and the ratio between x and y is y is 5 times greater than x, then y would equal 5, which is only true in A.
Or, use the number 5 as an example. If x = 5, and the ratio between x and y is y is 5 times greater than x, then y is 5.
And if you put that into A, y = 5x, it becomes 25 = 5(5)
Then 25 = 25, which is true!
Answer:
2.4 miles per hours
Step-by-step explanation:
if she traveled 1/5 of a mile in order for you ro do this you must first teun it into a full mile so times it by the required amount to equal one which would be five.
1/5 of a mile x 5 = 1
you must do this also to the time
5 minutes x 5 = 25 minutes
it takes her 25 minutes to travel one mile so because miles per hour is a ration you must find the amount in hours and not minutes.
So you must divide the hour equivilent by 25 minutes.
so if 1 hour equals 60 minutes
60 divided by 25 = 2.4
that is how you find miles per hour
Answer:
C. Both x is a function of y and y is a function of x
Step-by-step explanation:
A <u>function</u> is a relationship which assigns to each input (from the domain) value, a unique output (from the range).
y is a function of x means x is from domain, y is from range
x is a function of y means y is from domain, x is from range
1. Given 
y is a function of x because for each x there is exactly one y corresponding to this x.
2. Rewrite expressing x in terms of y:
x is a function of y because for each y there is exactly one x corresponding to this x.
Answer:
10,0
Step-by-step explanation:
this is because when you plot the points they are 10 apart and on the same level
