Solve y=4-0*x-0.5*9.8066*x^2

$$y=4-0 \times x-0.5 \times 9.8066 \times { x }^{ 2 }$$

Solve for y

$$y=-\frac{49033x^{2}}{10000}+4$$

Solution Steps

Anything times zero gives zero.

$$y=4-0-0.5\times 9.8066x^{2}$$

Subtract 0 from 4 to get 4.

$$y=4-0.5\times 9.8066x^{2}$$

Multiply 0.5 and 9.8066 to get 4.9033.

$$y=4-4.9033x^{2}$$

Solve for x (complex solution)

$$x=-\sqrt{\frac{40000-10000y}{49033}}$$

$$x=\sqrt{\frac{40000-10000y}{49033}}$$

Solve for x

$$x=\frac{\sqrt{\frac{160000-40000y}{49033}}}{2}$$

$$x=-\frac{\sqrt{\frac{160000-40000y}{49033}}}{2}\text{, }y\leq 4$$
