Answer:

7x+10

Step-by-step explanation:

match like terms

8x-x+6+4

7x+10

Answer:

[tex]7x+2[/tex]

Step-by-step explanation:

Alright. First, we have to remember that anything, even a minus sign, directly outside of a term in parentheses means that the term is being multiplied by that number or sign outside of it. A minus sign simply means -1.

I'm going to show you one method. There might be another one, but this method will be useful later in algebra.

So, we've established that a minus sign is actually -1. Now, let's rewrite the equation.

[tex](8x+6)-1(x+4)[/tex]

We'll simplify this now by removing the parentheses and distributing that -1.

[tex]8x+6-x-4[/tex]

Rearrange.

[tex]8x-x+6-4[/tex]

Combine like terms.

[tex]7x+2[/tex]

So,  [tex](8x+6)-(x+4)[/tex] equals [tex]7x+2[/tex].

Answer:

The 12-pound bag of dog food.

Step-by-step explanation:

To find out which is the better buy you start by divinging 10.80 by 12 and then you divide 10.20 by 8 and you get .90 cents for the 12 pound while you get 1.275 dollars. Which means the 12 pound bag is the better by because it is less money per pound than the 8 pound bag.

Answer: X = 1

Y= 5

Step-by-step explanation:

Plug in y = 3x + 2 in the Y coordinate to find X

-4x + 4(3x + 2) = 16

Now you can solve for X

X = 1

Then plug in 1 in the X coordinate to find Y

-4(1)+ 4y= 16

Now you can solve for Y

Y= 5

Step-by-step explanation:

Given, x=3y and y=x+4

y=3y+4.... substituting x=3y

y-3y=4

-2y=4

y=-2

Then substitute -2 either in x=3y or y=x+4 equations

x=3(-2)

=-6

The point-slope form of the equation of line it's y - y₁ = m(x - x₁), where m is the slope and (x₁, y₁) is the point the line passing through.

The slope-intercept form of the equation of line it's y = mx + b, where m is the slope and b is the y-intercept of the line.

1. Write the equation of the line that is parallel to y = 2x + 4 and passes through the point (-4, -1).

y=m₁x+b₁   ║   y=m₂x+b₂   ⇔    m₁ = m₂

{Two lines are parallel if  their slopes are equal}

y = 2x + 4  ⇒   m₁ = 2    ⇒    m₂ = 2

(-4, -1)  ⇒  x₁ = -4,  y₁ = -1

point-slope form:

y - (-1) = 2(x - (-4))

y + 1 = 2(x + 4)

y + 1 = 2x + 8               {subtact 1 from both sides}

2. Write the equation of the line that is parallel to y = ⅓x - 3 and passes through the point (3, -1).

y = ⅓x - 3  ⇒   m₁ =  ⅓    ⇒    m₂ =  ⅓

(3, -1)  ⇒  x₁ = 3,  y₁ = -1

point-slope form:

y - (-1) = ⅓(x - 3)

y + 1 = ⅓x - 1           {subtact 1 from both sides}

3. Write the equation of the line that is perpendicular to y = ¾x - 1 and passes through the point (3, -3).

y=m₁x+b₁   ⊥   y=m₂x+b₂   ⇔    m₁×m₂ = -1

{Two lines are perpendicular if the product of theirs slopes is equal -1}

y = ¾x - 1   ⇒   m₁ = ¾  

¾×m₂ = -1        ⇒    m₂ = -⁴/₃

(3, -3)  ⇒  x₁ = 3,  y₁ = -3

point-slope form:

y - (-3) =  -⁴/₃(x - 3)

y + 3 = -⁴/₃x + 4           {subtact 3 from both sides}

4. Write the equation of the line that is perpendicular to y = -x - 5 and passes through the point (7, 3).

y = - x - 5   ⇒   m₁ = -1  

-1×m₂ = -1        ⇒    m₂ = 1

(7, 3)  ⇒  x₁ = 7,  y₁ = 3

point-slope form:

y - 3 =  -1(x - 7)

y - 3 = - x + 7           {add 3 to both sides}

pic of question

Step-by-step explanation:

option D) The value of the center decreases and the distribution has a larger spread.

Mean is the measure of the central tendency or the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers.  

Given here the distribution as 121, 134, 106, 93, 149, 130, 119, 128

therefore their mean is = (121+134+106+ 93+ 149+ 130+ 119+ 128)/8

                                       = 122.5

Again after the new course was added the new mean is          

  =  (121+134+106+ 93+ 149+ 130+ 119+ 128+45)/9

 = 113.88

Hence clearly the mean has decreased and the distribution has a larger spread.

Answer:

a) 198.7% interest

Not too sure about answer to (b)

b) 4.75% annualized  

Step-by-step explanation:

a) i used Interest = Principal x Rate x Time

   40 = 525 x [tex]\frac{14}{365}[/tex] x r

    40 = 20.13r

    r = 1.987 or 198.7%

b) i used this proportion:   [tex]\frac{1.98}{1/24}[/tex] = [tex]\frac{x}{1}[/tex]      'x' represents annualized rate

                                                             1/24 represents 2 weeks out of a year

To know the scale factor here, just know that 16/4 = 4, and 8/2 = 4 too, so the scale factor is 4.

Just that the respective sides need to have the same ratio.

Answer by mathstudent55 give credit to him/her

Answer 7.5

Step-by-step explanation:

You can find this by dividing the number by 10, for example let’s use the number 20.

you would divide 20 by 10 which is 2 and times it by 7.

This is 14.

By finding this you have found 70% of 20.

now to find 5%, i would divide 20 by 10 once again which is 2 and then i would divide it by 2 which is 1.

then you would add the 2 numbers so 14+1 to get 15 therefore 75%of 20=15
