Answer:
I think its c but not really sure but ill calculate it if I ever had the chance
Answer:
Part A)
Part B)
Step-by-step explanation:
Par A) Write an equation that relates the distance D this car travels in T hours
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or
The speed is a proportional relationship between the distance and the time
Let
D ----> the distance in miles
T ----> the time in hours
so
In this problem the constant of proportionality k represent the speed of the car in miles per hour
we have

substitute
Part B) Use the equation to find the distance the car travels between 3:30 p.m. and 5:00 p.m
we know that
The time between 3:30 p.m. and 5:00 p.m is equal to
5:00 p.m-3:30 p.m=1.5 hours
so
For T=1.5 h
substitute in the equation and solve for D
B.) y=3x
The slope of a given line is defined by <em>y=mx+b</em>, where b is the y-intercept (the point at which the line crosses the y-axis) and m is the slope (rise/run). We see that the y-intercept is 0 (because the line hits the y-axis at 0) and the slope is 3 (rise=3 and run=1, so 3/1=3).
