what is the answer for 6x + 3(x-2)

Answer:

a) It's growing by 1 Hexagon in each term

b) (Self Explanatory, but if you still font know, just add 1 hexagon on the bottom tail)

c) 1-4

2-5

3-6

4-7

5-8

d) 1 hexagon is added each time

e) Common Difference = a1 - a

= 5 - 4

= 1

f) Consider the equation n + 3

where n is the number of terms.

In this case, n = 12

= 12 + 3

= 15 Hexagons

g) f(n) = 4 + 1(n-1)

f(1) = 4 + 1 ( 1 - 1)

f(1) = 4 + 1 (0)

f(1) = 4 + 0

f(1) = 4

1. The correct histogram (attached) that captures the frequency distribution is Option C.

2. Whether the data appear to have a distribution that is approximately normal, A. No, it is not symmetric.

A symmetric distribution is a distribution in which the left and right sides mirror each other and it is a normal distribution, with a distinct bell shape.

In a symmetrical distribution, mean = median = mode.  It is a skewed distribution when it is not symmetrical.

Hello!

We have to find the intersection of the two lines algebraically using substitution.

Given that y is x + 3, substitute x + 3 for y in the second equation to solve for x.

The solution for x is all real numbers, indicating that the solution to the system is also all real numbers.

A solution to the system is the point of intersection from all the lines.

If there are infinite solutions (all real numbers), there are an infinite number of intersections, or they are the same line.

Solving for y in the second equation:

Both equations are the same.

Thus, the upper class limits are- 29, 39, 49, 59, 69, 79, 89

Lower class limit is the smallest data value that can go in a class.

Thus, the lower class limits are- 20, 30, 40, 50, 60, 70, 80

The class midpoint is the average of the upper and lower limits of a class. Class midpoint = (upper limit + lower limit)/ 2

Thus, the class midpoints are- 24.5, 24.5, 44.5, 54.5, 64.5, 74.5, 84.5

Class boundary is the midpoint of the upper class limit of a class and the lower class limit of the previous class.

Thus, the  class boundaries are- 29.5, 39.5, 49.5, 59.5, 69.5, 79.5

Frequency gives us the number of individuals/ objects belonging to a particular class.

Thus, the number of individuals included in the summary = 27 + 32 + 15 + 3 + 5 + 1 + 1 = 84

The cost of a Token from the question is; $7.2

We are told that Jane and Jim spend the same amount of money today.

Now, Jim spent 5.25 dollars on food and rode the train 3 times, and Jane spent 12.45 dollars on food and rode the roller coaster twice.

Assuming cost of a token is T, the the algebraic expression formed is;

5.25 + 3T = 12.45 + 2T.

3T - 2T = 12.45 - 5.25

T = $7.2

Answer:

$350

Step-by-step explanation:

Let the cost of the bench be x. Then, the cost of the table is x+83.

[tex]x+x+83=783 \\ \\ 2x+83=783 \\ \\ 2x=700 \\ \ x=350[/tex]

The total cost is,

Let the cost of garden table be,

→ x + $83

Then the cost of bench will be,

→ (x + 83) + x = 783

→ 2x + 83 = 783

→ 2x = 783 - 83

→ x = 700/2

→ [ x = $350 ]

Hence, the cost of bench is $350.

Answer:idek

Step-by-step explanation:

The solution of the simultaneous equations is given by: x=0.60 and

y = 0.80 .

A system of equations or simultaneous equations, usually referred to as an equation system, is a collection of finite equations for which common solutions are sought.

The given pair of simultaneous equations are:

6 x + 8 y = 10

9 x + 6 y = 10.20

Now let us multiply the first equation by 6 and the second equation by 8 and subtract it from the first.

   36 x + 48 y = 60

   72 x + 48 y = 81.60

⇒ 36 x  = 21.60

⇒ x = 21.60 ÷ 36

⇒ x = 0.60

Substituting the value in the first equation we get:

y= 0.80.

Hence the solution of the simultaneous equation is x=0.60 and

y = 0.80 .

The linear equation has only one solution, which is x = 0.

Here we have the linear equation:

10x = 2.5*x

Let's solve this to see how many solutions we have, if we subtract 2.5x in both sides we get:

10x - 2.5x = 0

7.5x = 0

The only solution of this linear equation is x = 0.

7.5*0 = 0

Then we can conclude that the equation has only one solution, which is x = 0.

The missing coordinate of the points is 7

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

The given parameters are

Slope, m = 1/2

Points (x1, y1) = (x, 5) and (x2, y2) = (3, 3)

The slope of a linear equation is calculated as

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

So, we have

1/2 = (3- 5)/(3 - x)

Evaluate the differences

So, we have

1/2 = -2/(3 - x)

Cross multiply

So, we have

3 - x = -4

This gives

x = 3 + 4

Evaluate the sum

x = 7

The average annual wage of workers in the country will be at least $68400 in the year 2023 and after , the correct option is option (B) .

In the question it is given that

model of the average annual wage (y) = 2286x + 38620   ...(i)

where x = number of years after 2010,

It is also given that the average annual wage(y) must be at least 68,400 .

which means y ≥ 68400

Substituting value of y from equation (i) we get  ,

2286x + 38620 ≥ 68400

Simplifying the inequality further we get ,

2286x ≥ 68400 - 38620

2286x ≥ 29780

x ≥ 29780/2286

x ≥ 13.02 ≅ 13

Hence , the average annual wage will more than the specified value from the year, 2010+13 = 2023 .

Therefore , the average annual wage of workers in the country will be at least $68400 in the year 2023 and after , the correct option is option (B) .

Using proportions, the financial measures for the home purchase are given as follows:

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using the unit rates, which along with operations such as multiplication or division are used to find the equivalent measures.

For this problem, the beginning balance is the purchase value of the home, hence:

Beginning Balance: $220,000.

15% of that goes towards the down payment, hence:

0.15 x 220,000 = $33,000.

Payment toward principal: $33,000.

The number of monthly payments is given by:

20 x 12 = 360 monthly payments.

Considering the monthly payment, the ending balance is given as follows:

33,000 + 360 x 1,152.99 = $448,076.4.
