Answer:
Step-by-step explanation:
According to the information of the problem the plane is traveling at a constant velocity therefore the function that models that gives the distance of the plane from city B at time t hours would be linear. Something like this.
The velocity is the slope of the line and if you take B as your reference you would be going backwards therefore we would say that 
. And as I mentioned before if you take B as your reference your starting point would be 2070 miles away, therefore the function would be
The answer would be 56 pounds
Answer:
$65.59 more.
Step-by-step explanation:
We have the following:
A system of linear equations has infinite solutions when the graphs are exactly the same line.
for this to happen, on both sides the value of x must be equal:
replacing:
