Answer:
2x + 1
Step-by-step explanation:
That person added everything together that was shown which is incorrect. You shouldn't add the 12x + 3 as that should be the end result. You add 3x + 3x + 4x + 2 to get 10x + 2. You then subtract that by 12x +3 which is 2x + 1

What fraction of all the 10-digit numbers with distinct digits have the property that the sum of every pair of neighboring digits is odd?
Answer:
1/126
Step-by-step explanation:
Answer attached, I hope this is the answer.
the sum of every pair of neighboring digits is odd must be odd number and even number in the neighbor. (different parity)
The fraction of all the 10-digit numbers with distinct digits that have the property that the sum of every pair of neighboring digits is odd is 1/126.
What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.
We have two types of fractions.
Proper fraction and improper fraction.
A proper fraction is a fraction whose numerator is less than the denominator.
An improper fraction is a fraction where the numerator is greater than the denominator.
Example:
1/2, 1/3 is a fraction.
3/6, 99/999 is a fraction.
1/4 is a fraction.
We have,
For a 10-digit number to have the property that the sum of every pair of neighboring digits is odd, the digits must alternate between odd and even numbers.
Specifically, if the first digit is odd, then the second digit must be even, the third digit must be odd, the fourth digit must be even, and so on.
If the first digit is even, then the second digit must be odd, the third digit must be even, the fourth digit must be odd, and so on.
There are 5 odd digits and 5 even digits, so there are 5 choices for the first digit. After selecting the first digit, there are 5 choices for the second digit (it must be one of the other type), 4 choices for the third digit (it must be the opposite type of the second digit), 4 choices for the fourth digit (it must be the opposite type of the third digit), and so on.
Therefore, the number of 10-digit numbers with distinct digits that have the given property is:
5 x 5 x 4 x 4 x 3 x 3 x 2 x 2 x 1 x 1 = 5! x 4!
where the factorials arise from the number of choices for each digit.
The total number of 10-digit numbers with distinct digits is:
10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 10!
Therefore, the fraction of all the 10-digit numbers with distinct digits that have the given property is:
(5! x 4!) / 10! = (5! x 4!) / (10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1) = 1/126
Thus,
The fraction of all the 10-digit numbers with distinct digits that have the property that the sum of every pair of neighboring digits is odd is 1/126.

Answer:
do u have calculator?
Step-by-step explanation:
u need to put that equations in the graph
Answer:
y = -(x + 3)^2 - 5 (this is Answer b)
Step-by-step explanation:
Identify the coordinates of the vertex (h, k) by looking at the graph: the x-coordinate, h, is -3 and the y-coordinate is -5. The graph opens down, so the function begins with a negative sign: y = -(x + 3)^2 - 5 (this is Answer b).

Find the mean of the integers: –12, –4, –11, –6, 4 (Find the sum and divide by how many values there are.)
Answer:
The appropriate answer is "-5.8". A further solution is explained below.
Step-by-step explanation:
The given integers series is:
[tex]-12,-4,-11,-6,4[/tex]
As we know,
⇒ [tex]Mean=\frac{Sum \ of \ All \ Data \ Points}{Number \ of \ Data \ points}[/tex]
On substituting the values, we get
⇒ [tex]=\frac{(-12)+(-4)+(-11)+(-6)+4}{5}[/tex]
⇒ [tex]=\frac{-29}{5}[/tex]
⇒ [tex]=-5.8[/tex]
A local school needs to paint the floor of its theater room, where the length of the floor, x, is at least 12 feet. The width of the floor is 4 feet less than the length. It will have a stage and a closet, and the remaining area of the floor will be painted. The dimensions are shown in the diagram:
Let A represent the painted area, in square feet, of the floor. Choose the correct equation to solve for area (A).
A = x(x − 4) − 0.5(8)(x − 4) − 4(8)
A = x(x − 4) − (8)(x − 4) − 4(8)
A = x(x − 4) + (8)(x − 4) + 4(8)
A = x(x − 4) + 0.5(8)(x − 4) + 4(8)
Step-by-step explanation:
here .................
Answer:
A. A = x(x - 4) - 0.5(8)(x - 4) - 4(8)Step-by-step explanation:
Total area:
A(t) = x(x - 4)Area of the stage:
A(s) = 0.5(8)(x - 4)Area of the closet:
A(c) = 4(8)Area to be painted:
A = A(t) - A(s) - A(c)A = x(x - 4) - 0.5(8)(x - 4) - 4(8)Correct choice is A

Factor the following :
Answer:
(6x - 7y)(6x + 7y)
Step-by-step explanation:
36x² - 49y² ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , then
36x² - 49y²
= (6x)² - (7y)²
= (6x - 7y)(6x + 7y)
Answer:
(6x + 7y)(6x - 7y)
Step-by-step explanation:
36x² - 49y²
= (6x)² - (7y)²
= (6x + 7y)(6x - 7y)
In this question we used the identity-
a² - b² = (a + b)(a - b)

What is the equation of a circle that has a diameter of 10 units if its center is at (3,8)?
Answer:
Step-by-step explanation:
[tex](x-3)^2+(y-8)^2 = 25[/tex]
The equation of circle: (x - 3)² + (y - 8)² = 25
What is equation of circle?An equation of circle with center (h, k) and radius 'r' is,
(x - h)² + (y - k)² = r²
For given example,
a diameter of circle = 10 units
So, the radius would be (r) = 10/2
r = 5 units
And the center (h, k) = (3, 8)
So, the equation of the circle would be,
⇒ (x - 3)² + (y - 8)² = 5²
⇒ (x - 3)² + (y - 8)² = 25
Therefore, the equation of circle: (x - 3)² + (y - 8)² = 25

Which statement is true?
A.
The situation can be modeled by an exponential decay function with a percent change of -10%.
B.
The situation can be modeled by an exponential growth function with a percent change of 11%.
C.
The situation can be modeled by an exponential decay function with a percent change of -11%.
D.
The situation can be modeled by an exponential growth function with a percent change of 10%.
The situation can be modeled by an exponential decay function with a percent change of -10%, option A is correct.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
The ratio between the value after 1 year and the value after 0 years is 18,000/20,000 = 0.9.
The ratio between the value after 2 years and the value after 1 year is 16,200/18,000 = 0.9.
The ratio between the value after 3 years and the value after 2 years is 14,580/16,200 = 0.9.
Since the ratio between consecutive values is constant and less than 1, we can conclude that the situation can be modeled by an exponential decay function.
r = (18,000/20,000) - 1 = -0.1
So the percent change per year is -10%, which means that statement A is true.
Hence, the situation can be modeled by an exponential decay function with a percent change of -10%, option A is correct.

Mark is going to an awards dinner and wants to dress appropriately. He had one blue shirt, one white dress shirt, one black dress shirt, one pair of black slacks, one pair of grey slacks, and one red tie. All six of marks possible outfits are listed below
Answer:
All the four statements are true , which are -
(A) The subset contains contains of all the outfits that have grey slacks .
(B) The subset contains contains of all the outfits that have grey slacks and red tie .
(C) The subset contains contains of all the outfits that have grey slacks and blue shirt .
(D) The subset contains contains of all the outfits that do not have black slacks .
Step-by-step explanation:
We are given with Outfit 2 , 4 and 6
Outfit 2 - Blue grey red
Outfit 4 - White grey red
Outfit 6 - Black grey red
(A) Since only 2,4, and 6 contain grey slacks, and no other outfit contains grey slacks, those are the subsets that contain grey slacks. Thus , this statement is true .
(B) Just outfits 2, 4, and 6 have grey slacks and a red tie, proving the statement. Other clothes do not include grey slacks and a red tie; they may include a red tie but not both grey slacks and a red tie. Hence , the statement is true .
(C) Since the outfit 2 has grey slacks and a blue shirt, the statement is correct; no other outfit has both grey slacks and a blue shirt. Therefore , this statement is also correct .
(D) The argument is correct since all of the subsets contain grey slacks and no black slacks.
Hence , all the options A , B , C , D are correct and describes the subset .
