Answer:
A) gallons
B) Distance between Town A and Town B is miles
Step-by-step explanation:
A)
We know, number of gallons =
if miles per gallon (mpg) is given as 24 & total distance travelled is 3x miles, then, using formula we have:
Number of Gallons =
B)
Now, given is number of gallons = 2y & we know mpg is 24; <em>so what is the distance?</em>
We use the same formula and solve for distance (let distance between A and B be "D"):
For this case we have that by definition, the equation of the line of the slope-intersection form is given by:
Where:
m: It is the slope of the line
b: It is the cut-off point with the y axis
According to the statement data we have:
Then, the equation is of the form:
We substitute the given point and find "b":
Finally, the equation is of the form:
