Given the function F (x) 2/3 x -5 , evaluate f(9)

1 answer:

3 0

The f(9) = 1

first you plug in 9, where x is

f(9) = 2/3(9) - 5

multiply

f(9) = 6 - 5

subtract

and you should get f(9) = 1

What is this function written in vertex form? f(x) = (x –1)2 – 7 f(x) = (x 1)2 – 7 f(x) = (x –1)2 – 5 f(x) = (x 1)2 – 5

The vertex form of all expressions is given below.

We have given that the expressions

We have to write the function in vertex form.

<h3>What is the vertex form of the equation?</h3>

The vertex form of a quadratic function is given by f (x) = a(x - h)^2 + k, where (h, k) is the vertex of the parabola.

Therefore the first equation

$f(x)=(x-1)^2-7$

it can be written as

$f(x)=1(x-1)^2+(-7)$

The second equation can be written as

$f(x) = (x+1)^2 -7$

vertex for is,

$f(x)=1(x-(-1))^2+(-7)$

The third equation is,

$f(x) = (x -1)^2 - 5$

Vertex form is,

$f(x)=1(x-1)^2+(-5)$

Forth equation is,

$f(x) = (x +1)^2 +(- 5)$

Vertex form is,

$f(x) =1 (x -(-1))^2 +(- 5)$

A side of a square is 10 m longer than the side of an equilateral triangle the perimeter of the square is three times the perime

Slav-nsk [51]

Answer:

$\large \boxed{\text{8 m}}$

Step-by-step explanation:

Let side of triangle = x

And side of rectangle = y

Perimeter of triangle = 3x

Perimeter of rectangle = 4y

We have two conditions:

$\begin{array}{lrcl}(1) & y & = & x + 10\\(2) &4y & = & 3\times 3x\\& 4y & = & 9x\\& 4(x + 10) & = & 9x\\& 4x + 40 & = & 9x\\& 40 & = & 5x\\& x& = &\mathbf{8}\\\end{array}\\\text{Each side of the triangle is $\large \boxed{\textbf{8 m}}$ long.}$
