99=3/8g+2+12g+2
-4 -2 -2
95=3/8g+12g
95=12(3/8)g
(Divide both sides by 12(3/8))

Answer:

Step-by-step explanation:
Let  x be the distance driven, d-distance and C our constant.
Our information can be presented as:

#Subtracting equation 2 from 1: 

Hence the fixed cost per mile driven,
 is $0.20
To find the constant,
 we substitute 
 in any of the equations:

Now, substituting our values in the linear equation:
       #y=cost of driving, x=distance driven
Hence the linear equation for the cost of driving is y+0.2x+284
 
        
             
        
        
        
We'll do the first one.  I can't read the variable, but it looks like a 

 so that's what I'll use, but it doesn't matter.
First, get the variable by itself:

You get that before you multiply each side by two.  
 Now, you color the line so that all values that are less than 6 are shaded, so you put an open circle at 6 since it's not included and then you shade everything to the left.
