Answer:

n = ± 6

Step-by-step explanation:

absolute value equations usually produce 2 solutions

to get the positive solution just solve normally:  2n - 4 = 8

                                                                               2n = 12

                                                                                n = 6

to get the negative solution you must take what is in the absolute value bars and multiply by negative one:  -(2n) - 4 = 8

                                                   -2n - 4 = 8

                                                    -2n = 12

                                                      n = -6

Answer:

Mr. Lee takes home 9 kg of chocolate.

Mrs. Scarlet takes home 6kg of chocolate.

Step-by-step explanation:

Mr. Lee has a family of 6 people, and Mrs. Scarlett has a family of 4 people.

Together, the total number of people is 6 + 4 = 10

If we divide evenly the chocolate between all 10, then each one gets the same amount.

Then we need to do the quotient:

15kg/10 = 1.5kg

This means that each person gets 1.5kg of chocolate.

And Mr. Lee has 6 on his family, then the amount of chocolate that Mr. Lee takes home is 6 times 1.5 kg

6*1.5kg = 9kg

Mr. Lee takes home 9 kg of chocolate.

Mrs. Scarlett has a family of 4 people, then she takes home 4 times 1.5kg of chocolate, this is:

4*1.5kg = 6kg

Mrs. Scarlet takes home 6kg of chocolate.

The coordinates of the vertices of ∆X′Y′Z′:

Step-by-step explanation:

Given the triangle △XYZ with the vertices

It is stated that △XYZ is translated up 3 units to form the image ∆X′Y′Z′.

Translating 3 units UP means we have to add 3 units to all the y-coordinates of the coordinates of the vertices X, Y, and Z to generate the image ∆X′Y′Z′.

Thus,

THE RULE OF TRANSLATING 3 UNITS UP:

P(x, y) → P'(x, y+3)

Therefore, the coordinates of the vertices of ∆X′Y′Z′ will be:

X(-4, 6) → X'(-4, 6+3) → X'(-4, 9)

Y(1, 6) → Y'(1, 6+3) → Y'(1, 9)

Z(1, 1) → Z'(1, 1+3) → Z'(1, 4)

Thus, the coordinates of the vertices of ∆X′Y′Z′:

Step-by-step explanation:

Total number marbles Stacia has = 28

The ratio of red to blue marbles = 1 : 6

As the total number of marbles is 28. Thus,

r + b = 28

As the ratio of red to blue marbles is 1 to 6.

It means for each red marble 'r', we have 6 blue 'b' marbles. Thus,

b = 6r

now substituting b = 6r in the equation r + b = 28

r + b = 28

r + 6r = 28

7r = 28

divide both sides by 7

7r/7 = 28/7

r = 4

Thus,

The total number of red marbles ⇒ r = 4

The total number of blue marbles ⇒ b = 6r = 6(4) = 24

Therefore,

Answer:

[tex]a_{n}[/tex] = - 5n - 2

Step-by-step explanation:

There is a common difference between consecutive terms, that is

- 12 - (- 7) = - 17 - (- 12) = - 5

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 7 and d = - 5, then

[tex]a_{n}[/tex] = - 7 - 5(n - 1) = - 7 - 5n + 5 = - 5n - 2

Answer:

y=-1/2x-2

Step-by-step explanation:

I dont think any of those options are the right one so thats the correct answer

Answer:    y = -1/2x - 2

Step-by-step explanation:

To first write the equation, we need to find the slope and the y intercept and write it in the form  y=mx +b

To find the slope, we will find the difference between the y coordinates and divide it by the difference between the x coordinates.

The y coordinates of the points are , 0 and -2

The x coordinates of the points are -4 and 0

0 - (-2) = 2

-4 -0 = -4

Slope:  2/-4 = -1/2

Now using the formula y=mx+b, you will input the slope and use one of the given point's coordinates to solve for b the y intercept.

We will use the point (0,-2)

  -2 = -1/2(0) + b

-2 = b

  This means the equation will be  y = -1/2x - 2

Answer:

y= 3x+3

Let's solve for x.

y+3=−3(x−2)

Step 1: Flip the equation.

−3x+6=y+3

Step 2: Add -6 to both sides.

−3x+6+−6=y+3+−6

−3x=y−3

Step 3: Divide both sides by -3.

Answer:

The expression x = [tex]\frac{13}{8}+\frac{5}{4}[/tex] could be used to determine the amount of water drank altogether.

Step-by-step explanation:

Given that:

Amount of water drank during practice = [tex]1\frac{5}{8} = \frac{13}{8}[/tex]  liters

Amount of water drank on the ride home = [tex]1\frac{1}{4} = \frac{5}{4}[/tex] liters

Let,

x be the total amount of water drank by Ramona.

x = Water drank during practice + Water drank on the ride home

x = [tex]\frac{13}{8}+\frac{5}{4}[/tex]

Hence,

The expression x = [tex]\frac{13}{8}+\frac{5}{4}[/tex] could be used to determine the amount of water drank altogether.

Answer:

3/4

Step-by-step explanation:

12/16 = 3/4

The approximate probability that exactly one of the four characters will be a number is 44% option fourth is correct.

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

We have:

A randomly generated password contains four characters. Each of the four characters is either a lowercase letter or a digit from 0–9.

Total letters = 26

Total numbers = 10

Total = 10 + 26 = 36

Total possibilities = 36×35×34×33 = 1413720

Password with one number = C(10, 1) = 10

With three letters = C(26, 3) = = 2600

Outcomes = 2600×10 = 26000

Favorable outcomes = 26000×4! = 624000

Probability = 624000/1413720 = 0.44 = 44%

Thus, the approximate probability that exactly one of the four characters will be a number is 44% option fourth is correct.
