Answer:
The equation is 
whose solution is 
Step-by-step explanation:
Let us call 
the number of minutes the phone is used over 200 minutes, then we have
<em>(this says monthly bill of $40 plus the cost of phone usage over 200 minutes must equal $58 )</em>
This equation can be used to solve for u as follows:
It shows that a parabola can be described by tangents formed by lines with decreasing y-intercepts and equivalently increasing x-intercepts.
