Mathematics
A water taxi travels around an island in a path that can be modeled by the equation y = 0.5(x - 10)². A water skier is skiing along a path that begins at the point (8, 2) and ends at the point (14, 8). Write the linear equation that models the path of the skier.

Ответ:
You start with the equations:
Then you say y = y, then![-x^{2} - 4x = 2x + 5](/tpl/images/0476/8501/9fe38.png)
now you want to put all your numbers in one side of the equation and combine like terms in that side of the equation.
And now you have a quadratic equation, where you can determine the value of x using the Bhaskara method.
Then your solutions are x = -1 and x = -5.
