<em>Greetings from Brasil...</em>

X = 2 liter container

Y = 3 liter container

the total of containers are:

X + Y = 400

the capacity of the containers is

2X + 3Y = 1100

Assembling the equation system

2X + 3Y = 1100

X + Y = 400       x(-2)

2X + 3Y = 1100

<u>-2X  -2Y = - 800    </u>

<h3>Y = 300</h3>

X + Y = 400    so

X + 300 = 400

X = 400 - 300

<h3>X = 100</h3>

----------------------------------------------------------

<em>BR:</em>

<em>Observe que:</em>

<em>1 vasilha de 2L = 1 × 2 = 2L</em>

<em>2 vasilhas de 2L = 2 × 2 = 4L</em>

<em>3 vasilhas de 2L = 3 × 2 = 6L</em>

<em>X vasilhas de 2L = X × 2 = 2X litros</em>

<em>.....</em>

<em>1 vasilha de 3L = 1 × 3 = 2L</em>

<em>2 vasilhas de 3L = 2 × 3 = 4L</em>

<em>3 vasilhas de 3L = 3 × 3 = 6L</em>

<em>X vasilhas de 3L = X × 3 = 3X litros</em>

<em>Logo 2X + 3Y = 1100</em>

<em>Existem X e Y vasilhas que num total sao 400, logo</em>

<em>X + Y = 400</em>

Find the slope of a line parallel to this given line
dybincka [34]

bearing in mind that parallel lines have the same exact slope, then any parallel line to the one above will have the same slope as that one.

\bf \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array} \qquad \implies y = \stackrel{\stackrel{m}{\downarrow }}{-\cfrac{7}{3}}x-4

Given the polynomial 6x3 + 4x2 − 6x − 4, what is the value of the constant 'k' in the factored form? 6x3 + 4x2 − 6x − 4 = 2(x +
CaHeK987 [17]
First you graph it using a graphing calculator, you look at the table of values to find out one point in which y= 0. The first one that comes up is when x=1.
If you don't have a graphing calculator you can use trial and error by inputing some numbers into x until you get y= 0. 

Once you have an x value which makes y=0, you can start factorizing it. 
you divide 6x3 +4x2 -6x - 4 into (x-1) which is when y =0 
to get 6x2+10x+4 

This can be used to write the polynomial as (x-1)(6x2 +10x+4) 
you then factorize the second bracket, 6x2 +10x+4.
you can take the 2 outside to give you 2(3x2 +5x+2) 
you can factorize this to become 2(3x+2)(x+1) 

Now you just substitute your factorized second bracket into your unfactorized second bracket to give you 2(3x+2)(x+1)(x-1).

From this you can deduce that k= 1
