What is the axis of symmetry for the graph of y-4x=7-x^2

Len [333]

As you may know, the axis of symmetry will be a coordinate off the vertex of the equation, so...

$\bf y-4x=7-x^2\implies y=7-x^2+4x\implies y=-x^2+4x+7
\\\\\\
\textit{ vertex of a vertical parabola, using coefficients}\\\\
\begin{array}{llll}
y = &{{ 1}}x^2&{{ +4}}x&{{ +7}}\\
&\uparrow &\uparrow &\uparrow \\
&a&b&c
\end{array}\qquad 
\left(-\cfrac{{{ b}}}{2{{ a}}}\quad ,\quad {{ c}}-\cfrac{{{ b}}^2}{4{{ a}}}\right)
\\\\\\
\left(-\cfrac{4}{2(-1)}~~,~~7-\cfrac{4^2}{2(-1)} \right)\quad thus\implies \stackrel{\textit{axis of symmetry}}{x=~~~~-\cfrac{4}{2(-1)}}$

Find the value of x.

alex41 [277]

Answer:

x = 3.6

Step-by-step explanation:

If 2 chords of a circle intersect then the product of the parts of one chord is equal to the product of the parts of the other chord, that is

5x = 6 × 3 = 18 ( divide both sides by 5 )

x = 3.6
