1) An open box with length x feet,width y feet, and height 2 feet is shown below. It is known that the surface area for this box is 92 square feet and the equation to xy+4x+4y=92. Express the volume of this box as a function of x.
2) Two children were bouncing a ball. During one particular bounce, the ball traveled a horizontal distance of 6 feet and its maximum height above the ground was 4 feet. The path was in the shape of a parabala. Find the standard equation of the parabala described by this information. Let x replresent the horizontal distance in feet from the point the bounce started and y represent the height about the ground in feet.
3) IN math club, 1 team sold 2 different types of shirts. T shirts sold for 9 dollars a piece while sweatshirst sold for 16 dollars a piece. The secretary misplaced the individualized order forms but knows 57 total people placed an order and has written a check in the amound of 751 dollars to cover the entire order. If x represents the number of t shirts ordered and y the number of sweatshirts ordereed, choose the system of equations that can be used to find x and y. Do not solve.
