closed dot is if the number is part of the solution so if it is equal to

 and

use open if it is not part of solution as in if it is greater than or less than

 so for your picture x greater or equal to -2 it would be a closed dot

Gina measured the amount of water her friends drink each day in gallons. The line plot shows the measurements.
vova2212 [387]

Line plots are used to represent data using lines and dots

The difference between the greatest amount of water and the least is 1/2

From the line plot (see attachment), we have the following parameters:

Least = 8\frac 28

Greatest = 8\frac 68

<h3>Calculating the difference</h3>

The difference (d) is then calculated as:

d =Greatest -Least

So, we have:

d =8\frac 68 -8\frac 28

Subtract the common terms (8)

d =\frac 68 -\frac 28

Take LCM

d =\frac {6-2}8

d =\frac {4}8

Reduce the fraction

d =\frac {1}2

Hence, the difference between the greatest amount of water and the least is 1/2

What is the completely factored form of f(x)=x3+5x2+4x−6?
Gre4nikov [31]
f(x)=x^3+5x^2+4x-6
f(-3)=(-3)^3+5(-3)^2+4(-3)-6=0\implies x+3\text{ is a factor of }f(x)

Synthetic division yields

-3  |  1   5   4   -6
.    |      -3  -6    6
- - - - - - - - - - - - -
.    |  1   2  -2    0

which translates to

\dfrac{x^3+5x^2+4x-6}{x+3}=x^2+2x-2

with remainder 0. Now by the quadratic formula,

x^2+2x-2=0\implies x=\dfrac{-2\pm\sqrt{2^2-4(1)(-2)}}2=-1\pm\sqrt3

and so

f(x)=x^3+5x^2+4x-6=(x+3)(x-(-1+\sqrt3))(x-(-1-\sqrt3))
