Answer:

Equation: y = 0.25x + 7.50

Cost: $10.50

Step-by-step explanation:

Let x be the number of miles and y be the total cost in $.

y = 0.25x + 7.50

If we want to find the total cost of a 12 mi trip, we plug in x=12.

y = 0.25 * 12 + 7.50

y = 3 + 7.50

y=10.50

The requested equation is


C(m) = 7.50 + 0.25*m,


where C(m) is the total cost (in dollars) for "m" miles.


Make the plot on your own.

Find c such that (−3,−8), (−7,−6), and (c,4) lie on a line.
Nutka1998 [239]
If the 3 points are collinear, then the slopes of all line segments connecting the points are the same.

Thus, 

         -6 - (-8)         2
m = ------------- = -------- = -1/2
         -7 - (-3)         -4

Then the following must be true:

             4-(-6)          10
-1/2 = ------------ = ---------
             c - (-7)       c + 7

Cross multiplying, -(c+7) = 20, and c+7 = -20, so that c = -27

Hello from MrBillDoesMath!

Answer:  13

Discussion:

Evaluate f(g(3)).

g(3) = 3^2 -4 = 5 so

f(g(3)) = f(5) = 3*5-2 = 15 -2 = 13


Thank you,
