Segment AH is parallel to BD and if the lines were drawn out infinitely, the two lines would never meet.
        
             
        
        
        
An easier way to think of this problem is just keep adding for each additional hour: 
0.5 hours --> $2 
1.5 hrs --> $3.75 
2.5 hrs --> $5.50 
3.5 hrs --> $7.25 
and since you can only spend $7, the maximum time is 2.5 hours
 
        
                    
             
        
        
        
8 foot path
1st step = 8/2 = 4ft
2nd step = 4/2 = 2ft
3rd step = 2/2 = 1ft
4th step = 1/2 = 1/2ft
So he covered 7 1/2 ft (or 7.5ft)

Four different ways to solve a quadratic equation are factoring, completing the square, quadratic formula, and graphing. all methods start with setting the equation equal to zero.
to determine the zeros of a quadratic graph, find the points where the graph of the quadratic equation crosses the x-axis. to determine the vertex, you convert the quadratic form to vertex form, you use this process of completing the square. to determine the axis of symmetry, you cut the graph vertically to see the symmetrical sides.
