Question 1021939
Your question A seems to be already answered in the description.  You already know the equation because it is given.  Just make into an inequality instead.


Question B:
The center under the arch at ground level receives 3 feet on one side of the camper vehicle and 3 feet on the other side of the camper vehicle; totalling 3+3=6 feet for the length.  Evaluate y when x=3.  Is y less than 7 or not less than 7 ?
