Answer: x=2.25

Step-by-step explanation:

-3x+10=5x-8

+3x +3x

10=8x-8

+8 +8

18=8x

18/8=8x/8

2.25=x

HELPPPPPPPPPPP<br> Draw the graph of y = 2x + 3 on the grid

topjm [15]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

$y=2x+3$

This is the equation of the line

To graph a line we need two points

<em>Find the intercepts</em>

1) The y-intercept is the value of y when the value of x is equal to zero

For x=0

$y=2(0)+3$

$y=3$

The y-intercept is the point (0,3)

2) The x-intercept is the value of x when the value of y is equal to zero

For y=0

$0=2x+3$

$x=-3/2=-1.5$

The x-intercept is the point (-1.5,0)

To draw the graph of the line plot the intercepts and join the points

using a graphing tool

see the attached figure

According to the fundamental Theorem of algebra, which polynomial function has exactly 11 roots?

liraira [26]

<h2>Explanation:</h2><h2></h2>

The Fundamental Theorem of Algebra states the following:

<em>For</em><em> </em><em>any polynomial of degree n we will have n roots.</em>

<em />

So the general form of the equation of a polynomial is:

$A \ \mathbf{polynomial \ function} \ of \ x \ with \ degree \ n \ is \ given \ by:\\ \\ f(x)=a_{n}x^{n}+a_{n-1}x^{n-1}+\ldots +a_{2}x^{2}+a_{1}x+a_{0} \\ \\ where \ n \ is \ a \ nonnegative \ integer \ and \ a_{n}, a_{n-1}, \ldots a_{2}, a_{1}, a_{0} \\ with \ a_{n}\neq$

Since our polynomial will have exactly 11 roots, then the equation will have the following form:

$f(x)=a_{11}x^{11}+a_{10}x^{10}+\ldots +a_{2}x^{2}+a_{1}x+a_{0}$
