IF 12x = -8(10 - x), then x=​

Answer:

B. x = -5

Step-by-step explanation:

-8(x+5) = -3x - 7 + x  - 3

distribute the -8

-8x - 40 = -3x - 7 + x - 3

combine like terms

-8x - 40 = -2x - 10

add 40 to both sides

-8x = -2x + 30

add 2x to both sides

-6x = 30

divide both sides by -6

x = -5

Answer:

Step-by-step explanation:

The marked price is 39.98

The tax is 4.5%

That means that the tax is added on to the marked price to get the selling price.

One way to do is is to multiply by the tax factor.

The tax factor is 1 + 4.5/100 = 1.045

So the Selling price = 39.98 * 1.045

Selling price = 41.78 rounded to 2 decimal places.

The more standard way of doing this is to multiply the tax by the marked price and add that on to the marked price to get the selling price.

39.98 * 4.5/100  = 1.7991

39.98

  1.7991        Add

41.7791

The difference comes in where you do the rounding. The second way to do this has no rounding. If you convert this to money, the answer will be 41.78, just as the first way's answer.

Graph attached

Shading should be done from 3 to 15/2 or 7.5

It should be open dot

Step-by-step explanation:

first let's bring the equation into "normal" form :

x - 2y = 2

-2y = 2 - x

2y = x - 2

y = x/2 - 1

so, the slope of this line is 1/2 (the factor of x - that is always the case in all lines).

a parallel line must have the same slope, of course.

so, its equation is

y = x/2 + b

now, b will be different to the -1 of the original equation, or the lines are identical.

it is the point of interception of the line through the y-axis (x = 0).

we get this by using the coordinates of the given point (4, -3).

so,

-3 = 4/2 + b = 2 + b

b = -5

therefore, the formula for the parallel line is

y = x/2 - 5

Answer:

  X.

Step-by-step explanation:

The inequalities tell you the graph is below a solid line that goes up to the right, and below a dashed line that goes down to the left. The upward sloping line has a slope of 2, so is steeper than the downward sloping line that has a slope of -1.

The colored portion will be in the bottom quarter of the X made by the crossing lines. The appropriate graph is X.

The equation y + 5 = [tex]\frac{3}{4}[/tex] ( x - 12) can be rearranged into slope intercept form as y = [tex]\frac{3}{4}[/tex] x + (-14).

What is the slope intercept form of a line ?

The equation of line that can be written as y = mx + c, where m is the slope and c is the line's y-intercept, is known as a slope intercept form.

An equation is given which is :

y + 5 = [tex]\frac{3}{4}[/tex] ( x - 12)

If we multiply by 4 on both sides , we get :

4y + 20 = 3x - 36

or

4y = 3x - 56        -- -- -- -- --- ---- ----- ----- --- --- --- Equation 1

We know that the slope intercept form of a line is given by :

y = mx + c

So , to change the above equation into slope intercept form we must divide equation 1 by 4. So , the rearranged equation will be :

4y / 4 = (3/4 x ) - (56 / 4)

y = [tex]\frac{3}{4}[/tex] x + (-14)

Therefore , the equation y + 5 = [tex]\frac{3}{4}[/tex] ( x - 12) can be rearranged into slope intercept form as y = [tex]\frac{3}{4}[/tex] x + (-14).

Answer:

1.6 is a rational number while 1.4 is not

16 and 10 are rational numbers so 1.6 will also be a rational number

√2 is 1.4 while the square of 1.4 is not 2

√2.56 is 1.6 and the square of 1.6 is 2.56

The answer is

→ [tex]-4 \frac{4}{35}[/tex]

Step-by-step explanation:

[tex]3\frac{2}{7} - 7\frac{6}{15}[/tex]

[tex]=\frac{23}{7} - 7\frac{6}{15}[/tex]

[tex]=\frac{23}{7} - 7\frac{2}{5}[/tex]

[tex]=\frac{23}{7} - 7\frac{37}{5}[/tex]

[tex]=\frac{-144}{35}[/tex]

[tex]=-4 \frac{4}{35}[/tex]

Therefore, [tex]-4 \frac{4}{35}[/tex] is your answer.

Hope this helped! :^)

Answer:

2.83

Step-by-step explanation:

use formula and replace x and y with the given values

Step-by-step explanation:

Finding b

If we use the given slope and use one of the points to write the equation in point-slope form (y - y₁) = m(x - x₁)), we can rearrange it to find the y-intercept:

Using (4,4)  

                                ⇒  y - 4 =  - 0.5 (x - 4)

                                     y - 4 = - 0.5 x + 2

                                          y = -0.5 x + 6

Calculating 'n' and 'p'

We can find n and p by plugging the points into the newly found equation   y = -0.5 x + 6.

For n using (7, n)

             since  y = -0.5 x + 6

                        n = -0.5 (7) + 6

For p using (3,p)

               since y = -0.5 x + 6

                         p = - 0.5 (3) + 6

                         p = - 1.5 + 6

Checking the answer

We can check the answer we got in two ways:

         Using the points (4, 4) and (7, n) as (x₁, y₁) & (x₂, y₂)   respectively

         The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)  

                               - 0.5  =  (n - 4) ÷ (7 - 4)

                               - 0.5 =  ⁿ⁻⁴/₃          [multiply both sides by 3]

                                - 1.5 = n - 4           [add four to both sides]

                                    n = 2.5     [this matches the value of n we found]
