Distance traveled by an airplane in 7 hours = 4,914 kilometers
We have to determine the unit rate for kilometers per hour.
So, distance traveled by an airplane in 1 hour = 
= 702 kilometers.
So, an airplane will travel 702 kilometers in an hour.
Therefore, the unit rate for kilometers per hour is 702 km per hour.
Answer: a relationship/connection between two variables, there are negative and positive correlations.
Answer:
A. y = -16
Step-by-step explanation:
Hello!
What we do to one side of the equation we have to do to the other.
y + 7 = -9
We have to get y by itself so we have to get rid of the seven by doing the opposite of what it says
The opposite of addition is subtraction so we subtract 7 from both sides
y + 7 - 7 = -9 - 7
Solve
y + 0 = -16
Simplify
y = -16
The answer is A. y = -16
Hope this helps!
