Yes, they are both functions.
D. 25 units
They all meet on the graph at that point
Answer: 0.25 or 1/4
Step-by-step explanation:
1/2*2 = 1/2^2 = 1/4
. Distance = Speed * Time
Let s represent the speed of the cars in miles per hour. The problem statement tells you
.. red car distance + 25 miles = blue car distance
.. s*3 + 25 = s*(3 + 0.5)
.. 25 = 0.5s ... subtract 3s from both sides
.. 50 = s ... multiply by 2
The speed of the red and blue cars is 50 miles per hour.
Division can be used. For example
50/16=3.125gallons
or you could use multiplication
50*1/16=3.125gallons
