Pulling out like terms

4.1     Pull out like factors :

  6k3 + 10k2 - 56k  =   2k • (3k2 + 5k - 28)

Trying to factor by splitting the middle term

4.2     Factoring  3k2 + 5k - 28

The first term is,  3k2  its coefficient is  3 .

The middle term is,  +5k  its coefficient is  5 .

The last term, "the constant", is  -28

Step-1 : Multiply the coefficient of the first term by the constant   3 • -28 = -84

Step-2 : Find two factors of  -84  whose sum equals the coefficient of the middle term, which is   5 .

     -84    +    1    =    -83

     -42    +    2    =    -40

     -28    +    3    =    -25

     -21    +    4    =    -17

     -14    +    6    =    -8

     -12    +    7    =    -5

     -7    +    12    =    5    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -7  and  12

                    3k2 - 7k + 12k - 28

Step-4 : Add up the first 2 terms, pulling out like factors :

                   k • (3k-7)

             Add up the last 2 terms, pulling out common factors :

                   4 • (3k-7)

Step-5 : Add up the four terms of step 4 :

                   (k+4)  •  (3k-7)

            Which is the desired factorization

Final result :

 2k • (3k - 7) • (k + 4)

Answer:

8/-5

Step-by-step explanation:

the equation for slope is y 2 - y 1/ x 2 - x 1 so your equation is -7 - (-11) / -6 - (-1) which simplifies to  8/ -5 and that is the slope.

Answer:

Option (C)

Step-by-step explanation:

There are two inequalities,

t - 4 ≥ 4t + 8 ------(1)

3t > 14 - 4t ------(2)

By simplifying inequality (1),

t - 4 ≥ 4t + 8

t ≥ 4t + 8 + 4

t ≥ 4t + 12

t - 4t ≥ 12

-3t ≥ 12

t ≤ [tex]\frac{12}{(-3)}[/tex]

t ≤ -4

By solving inequality (2),

3t > 14 - 4t

3t + 4t > 14

7t > 14

t > [tex]\frac{14}{7}[/tex]

t > 2

From the given graphs, Option (C) will be the answer.

Using reflection concepts, it is found that the correct option is:

I alr did the quiz for this question on edg 2020

Answer:

x= 6

Step-by-step explanation:

Answer:(6,0)

Step-by-step explanation:

Its the only positive point on the x axis

The ordered pair on the x axis that is one the line parallel to the given point P ( -6 , 10 ) is Q ( 6 , 0 )

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the first point be P ( -8 , 6 )

Let the second point be Q ( 4 , -4 )

Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( -4 - 6 ) / ( 4 + 8 )

Slope m = -5/6

Now , the equation of line is y - y₁ = m ( x - x₁ )

y + 4 = ( -5/6 ) ( x - 4 )

Subtracting 4 on both sides , we get

y = -5 x/6 - 4/6

Now , the ordered pair be ( 6 , 0 )

5x + 6y + k=0,  passes through ( -6 , 10 )

So , ( -30 + 60 + k = 0 )

k = -30

And , the line is 5x + 6y - 30 =0

So , the ordered pair ( 6 , 0) satisfies the condition of the equation

Hence , the ordered pair is ( 6 , 0 )

Let the width of the rectangle be 'w'

According to the question length of the rectangle (l) is three feet more than twice it's width;

[tex] \longrightarrow [/tex] l = (2w + 3) ft

Perimeter of rectangle = 78 ft

Formula of perimeter of rectangle = 2(Length + Width)

So,

[tex] \rm \implies 2(Length + Width) = 78 \\ \\ \rm \implies 2(2w + 3 + w) = 78 \\ \\ \rm \implies 2(3w + 3) = 78 \\ \\ \rm \implies 2 \times 3(w + 1) = 78 \\ \\ \rm \implies 6(w + 1) = 78 \\ \\ \rm \implies w + 1 = \dfrac{78}{6} \\ \\ \rm \implies w + 1 = 13 \\ \\ \rm \implies w = 13 - 1 \\ \\ \rm \implies w = 12 \: ft[/tex]

[tex] \therefore [/tex] Width of the rectangle (w) = 12 ft

Answer:

[tex]Change = \$10.25[/tex]

Step-by-step explanation:

Given

[tex]Individuals = 4[/tex] (You and 3 friends)

[tex]Total = \$20.00[/tex]

[tex]Movie = \$6.25[/tex] per individual

[tex]Popcorn = \$3.50[/tex]

Required

Determine the change

First, we need to determine the total amount spent on movie ticket.

The question does not state whether I pay for my friend's ticket.

So, we'll work on what is obvious.

i.e

[tex]Amount\ Spent\ on\ Ticket = \$6.25[/tex]

Add this amount to the amount spent on popcorn

[tex]Amount\ Spent =\$6.25 + \$3.50[/tex]

[tex]Amount\ Spent =\$9.75[/tex]

To get the Change, we have to deduct the total amount spent from the amount given by mom

[tex]Change = \$20 - \$9.75[/tex]

[tex]Change = \$10.25[/tex]

Hence:

The change is $10.25
