\frac{29}{10}  = x +  \frac{1}{x} \\ 29 = 10x +  \frac{10}{x}   \\ 10x - 29 +  \frac{10}{x} = 0  \\ 10 {x}^{2}  - 29x + 10 = 0 \\  \frac{29 +  \sqrt{841 - 400} }{20}  = x \\  \frac{29 +  \sqrt{441} }{20}  = x \\  \frac{29 + 21}{20}  =  \frac{50}{20}  = 2 \frac{1}{2} = x  \\ or \\  \frac{29  -   \sqrt{841 - 400} }{20}  = x \\  \frac{29  -   \sqrt{441} }{20}  = x \\  \frac{29  -  21}{20}  =  \frac{8}{20}  = \frac{2}{5} = x

Answer:

\frac{5+-\sqrt{53} }{2}

Step-by-step explanation:

in the equation given these are the values:

a=1   b= -5     c= -7

if we plug this in the quadratic formula \frac{-(-5)+-\sqrt{(-5)^2-4(1)(-7)} }{2(1)}

this is simplified to \frac{5+-\sqrt{53} }{2}

On a coordinate plane, a curved line with a minimum value of (negative 1.25, negative 3.25) and a maximum value of (0.25, negati
soldier1979 [14.2K]

The statement which is true about the end behavior of the graphed function is third option that is as the x-values go to negative infinity, the function's values are equal to zero.

A coordinate plane is a two dimensional plane formed by the intersection of two number lines . One of these number lines is a horizontal number lines called the x-axis and the other number line is a vertical number line called the y-axis.

The exact answer is third option that is as the x-values go to negative infinity, the function's values are equal to zero.

Step by step explanation:

Minimum value (negative 1.25, negative 3.25)

Maximum value of (0.25, negative 1.75)

The x intercepts where the graph crosses the x axis.

Value of x when y=0 crosses x axis at (negative 2.25, 0)

The y intercept are where the graph crosses the y axis.

Value of y when x=0 crosses y axis at (0, negative 2)

The line exits the plane at (negative 2.75, 6) and (1.5, 6).

It can be seen from the coordinates that as the x-values go to negative infinity, the function's values are equal to zero, the coordinates of y approaches zero.
