<h3>What is Quadratic Equation?</h3>

A quadratic equation is a second-order polynomial equation in a single variable x, ax²+bx+c=0. with a ≠ 0 .

Given:

y= -16x²+33x+45

If the height is 30 feet.

30= -16x²+33x+45

-16x²+33x+45-30=0

-16x²+33x+15=0

16x²-33x-15=0

Solving the quadratic equation

x=-b±√b²-4ac/ 2a

x= 33 ± √2049/32

x= (33+ √2049)/32    and x=33-√2049/32

x=2.44 and -0.3833

The system has two solutions.

You can tell because the second equation is a quadratic and the first is a line, so the line passes through the quadratic twice.

Solve for x 73 =(9/10x)+19
Yuliya22 [10]
73=(\frac{9}{10}x)+19

To solve x:

1. Substract 19 in both sides of the equation:

\begin{gathered} 73-19=(\frac{9}{10}x)+19-19 \\  \\ 54=\frac{9}{10}x \end{gathered}

2. Multiply both sides of the ewuation by 10/9:

\begin{gathered} 54\cdot\frac{10}{9}=\frac{9}{10}x\cdot\frac{10}{9} \\  \\ \frac{540}{9}=x \\  \\ 60=x \end{gathered}<h2>Then, the value of x is 60 (x=60)</h2>
