Suppose a soccer goalie punted the ball in such a way as to kick the ball as far as possible down the field. The height of the b
all above the field can be approximated by the function below where y represents the height of the ball (in yards) and x represents the horizontal distance (in yards) down the field from where the goalie kicked the ball. How far away did the ball land? Estimate to 2 places after the decimal.
Multiply the first equation by -2 to eliminate a variable so it becomes: -12x+8y=48 4x-8y=-32 Add them together. -8x=16 x=-2 Plug it in one equation. 6(2)-4y=-24 12-4y=-24 -4y=-12 y=3 Ordered pair is: (-2,3)
