A fountain on a lake sprays water in a parabolic arch modeled by the equation y = −0.4x2 + 3x, where y is the height in feet and x is the horizontal distance. A beam of light is passed through the fountain to create a rainbow effect. If the beam is directed at an angle modeled by the equation -2.2x + 4.9y = 8.18, at what distance from the ground will the beam first touch the water spray?

The number of times 2 can take away from 100 bricks is
Further explanation:
Given:
There are 100 bricks in a lot and we have to take 2 bricks away from the lot.
Explanation:
If we take 2 from 100 we left with 100 - 2 = 98.
If we take 2 from 98 we left with 98 - 2 = 96.
If we take 2 from 96 we left with 96 - 2 = 94.
Similarly we can take 2 bricks from 94 and left with 92 bricks and 2 bricks from 92 bricks and left with 90 bricks.
The number of bricks that can be taken 2 bricks away from the 100 bricks can be calculated as follows,
