The function g is given in three equivalent forms.<br> Which form most quickly reveals the vertex?
Nadusha1986 [10]

Answer:

Option A. g(x)= \frac{1}{2}(x-8)^2-8

Step-by-step explanation:

<u><em>The complete question is</em></u>

The function g is given in three equivalent forms.

Which form most quickly reveals the vertex?

A)g(x)= 1/2(x-8)^2-8

B)g(x)= 1/2(x-12)(x-4)

C)g(x)= 1/2x^2-8x+24

we know that

The equation of a quadratic function in vertex form is equal to

y=a(x-h)^2+k

where

a is the leading coefficient

(h,k) is the vertex of the function

In this problem, the option A is the equation of the function in vertex form

we have

g(x)= \frac{1}{2}(x-8)^2-8

where the vertex is the point (8,-8)

therefore

Option A

Find the solution to the following system of equations. x-2/3y=8 -1/5x+1/3y = 3
Anastaziya [24]

<em>Note: Your question sounds a little unclear, but I am assuming that your system of equations is:</em>

x-\frac{2}{3}y=8

-\frac{1}{5}x+\frac{1}{3}y\:=\:3

It would anyways clear your concept because the procedure to find the solutions remains the same for any set of a system of equations.

Answer:

The solution of the system of equations be:

x=\frac{70}{3},\:y=23

Step-by-step explanation:

Given the system of equations

\begin{bmatrix}x-\frac{2}{3}y=8\\ -\frac{1}{5}x+\frac{1}{3}y=3\end{bmatrix}

\mathrm{Multiply\:}-\frac{1}{5}x+\frac{1}{3}y=3\mathrm{\:by\:}5\:\mathrm{:}\:\quad \:-x+\frac{5}{3}y=15

\begin{bmatrix}x-\frac{2}{3}y=8\\ -x+\frac{5}{3}y=15\end{bmatrix}

so adding the equation

-x+\frac{5}{3}y=15

+

\underline{x-\frac{2}{3}y=8}

y=23

so the system equations become

\begin{bmatrix}x-\frac{2}{3}y=8\\ y=23\end{bmatrix}

\mathrm{For\:}x-\frac{2}{3}y=8\mathrm{\:plug\:in\:}y=23

x-\frac{2}{3}\cdot \:23=8

x-\frac{46}{3}=8

Add 46/3 to both sides

x-\frac{46}{3}+\frac{46}{3}=8+\frac{46}{3}

x=\frac{70}{3}

Therefore, the solution of the system of equations be:

x=\frac{70}{3},\:y=23
