Step-by-step explanation:
here's the answer to your question
Answer:
B.
Step-by-step explanation:
You pay a one time fee of 18 dollars and then 2 dollars per ride.
The expression for that is 18+2r where r represents the number of rides and the output of (18+2r) is amount you spend.
f(r)=2r+18 when compared to f(x)=mx+b where m is slope and b is y-intercept
you should see that the slope is $2 per ride.
B. is the option that says this.
Answer:
x=1 and x =5
Step-by-step explanation:
We want to know when it crosses the x axis (f(x) =0) . From the graph, we can see the x value when y=0 is x=1 and x =5
If the body is accelerating then the graph would probably display a line going higher.
Answer:
80 minutes or 1 hour 20 min
Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
Let
s -----> the speed in miles per hour
d ----> the distance in miles
t ----> he time in hours
so

solve for t

we have


substitute and solve for t


Convert to minutes
