Explanation:

x is a variable or placeholder for a number. Think of it like a box.

1x = 1 box

2x = 2 boxes

and so on

9x = 9 boxes

5x = 5 boxes

9x+5x = 9 boxes + 5 boxes = 14 boxes = 14x

So that's one way to see how 9x+5x = 14x.

Or you could add the coefficients 9 and 5 to get 9+5 = 14. Then tack an x onto everything.

----------

The y terms are handled in a similar fashion.

-5y + 9y = 4y

which is the same as

9y - 5y = 4y

You could think of it like this

(9 yaks) - (5 yaks) = 4 yaks

So we started with 9 yaks and took away 5 of them to be left with 4 yaks.

----------

After getting the results 14x and 4y. We would then have the final answer 14x+4y

The x and y terms cannot be combined since they are not like terms. So we leave that expression as is.

Answer:

The order of the matrix D^T × (BE) is 2 × 4

Step-by-step explanation:

In the multiplication of matrix, the number of columns in the first matrix must be equal to the number of rows of the second matrix. The resulting matrix from the product will have the same number of rows as the first matrix and the same number of column as the second matrix. For example, given Matrix A of order (m × n) and Matrix Z of order ( n × k), the product of the two matrices will give a matrix ( say Y) of order (m × k).

AZ = Y

(m x n)(n x k) = (m x k)

Now, From the question,

The order of Matrix B is 4 × 5,

the order of the matrix D is 4 × 2

and the order of the matrix E is 5 × 4.

To determine the order of the matrix D^T × (BE)

First, will find the order of (BE)

Order of BE = (4 × 5) (5 × 4)

Order of BE = (4 × 4)

Hence, the order of matrix (BE) is 4 × 4.

Now, we will determine the order of matrix D^T

D^T means the transpose of matrix D.

The transpose of a matrix is defined as a new matrix whose rows are the columns of the original matrix and the columns of the new matrix are the rows of the original matrix. This means given Matrix A of order (m × n), the transpose of Matrix A (A^T) will have an order of (n × m).

The order of the matrix D is 4 × 2

Hence, the order of the transpose of matrix D (D^T) will be 2 × 4

Now, the order of the matrix D^T × (BE) will be

Order of the matrix D^T × (BE) = (2 × 4) × (4 × 4)

Order of the matrix D^T × (BE) = 2 × 4

Hence, the order of the matrix D^T × (BE) is 2 × 4.

Answer:

x = - 9, x = - 4

Step-by-step explanation:

Set (x +)(x + 9) equal to zero, that is

(x + 4)(x + 9) = 0

Equate each factor to zero and solve for x

x + 4 = 0 ⇒ x = - 4

x + 9 = 0 ⇒ x = - 9

Thus

x = - 9, x = - 4

f(x) = (x-8)/(x+7) and g(x) = (-7x-8)/(x-1)

To confirm that f(x) and g(x) are inverses.

f(g(x)) = x

g(f(x)) = x

f(g(x)) = (((-7x-8)/(x-1))-8)/(((-7x-8)/(x-1))+7)

f(g(x)) = (-15x² -15x)/(-15x² - 15)

f(g(x)) = -15x/-15

f(g(x)) = x

g(f(x)) = (-7((x-8)/(x+7))-8)/(((x-8)/(x+7))-1)

g(f(x)) = (-15x² - 105x)/(-15x²- 105)

g(f(x)) = -105x/-105

g(f(x)) = x

f(x) and g(x) are inverses.

Answer:

Coffees cost $2 each and bagels cost $4 each

Step-by-step explanation:

Let

Coffee=c

Bagels= b

2 coffees and 5 bagels for which he paid $24

2c + 5b= 24 (1)

he returned to buy 3 coffees and 4 bagels for

$22

3c + 4b = 22 (2)

2c + 5b= 24 (1)

3c + 4b = 22 (2)

Multiply (1) by 3 and (2) by 2

6c + 15b = 72 (3)

6c + 8b = 44 (4)

Subtract (4) from (3)

15b - 8b = 72 - 44

7b = 28

Divide both sides by 7

b= 28 / 7

= 4

b= $4

Substitute b=4 into (1)

2c + 5b= 24

2c + 5(4) = 24

2c + 20 = 24

2c = 24 - 20

2c = 4

Divide both sides by 2

c= 4 / 2

c= $2

Therefore,

Coffees cost $2 each and bagels cost $4 each

Answer:

Yes.  It needs to be clear that it is on going.  So as long as it is evident that it repeats, you're good.

Step-by-step explanation:

Answer:

The correct option is;

16 inches

Step-by-step explanation:

The parameters of the motion given are;

The diameter, D of the bicycle = 16 inches;

The distance the bike moves (forward) after the screw punctures the tire = 56·π inches

We note that the circumference of the bicycle = π·D = π × 16 = 16·π inches

Therefore;

56·π inches/(16·π inches) = 3.5

Showing that the bicycle moves three and half complete turns (revolution) where after each complete turn, the screw starts from the bottom of the tire.

The height, h of the screw in the final half turn is given by the relation;

h = A×cos(Bx - C) + D

A = Amplitude of the motion = Diameter/2 = 16/2 = 8

P = The period of the motion 2·π/B

B·x = The angle described by the motion = Half of one revolution = π = 180°

C = Phase shift = π

D = The midline = Diameter/2 = 8 inches

Therefore;

h = 8×cos(π - π) + 8 = 16 inches

After the bike moves forward another 56·π inches the height of the screw = 16 inches.

Answer:

16 inches

ACT score percentile help colleges compare students with one another, rather than just looking at everyone’s score. The  score range is between 1 and 36, the highest score that one can receive on the ACT is 36. Moreover, 36 is the perfect score.

The maximum ACT score (36) is that in 2018, only 3,741 students (out of millions of test-takers) scored a perfect 36 on the ACT.  The 99th percentile of test-takers includes those who earn 35 or 34 on the ACT. We can miss up to five questions on the ACT and still earn a 36. That is a reason why the maximum ACT score is 36 at the 100th percentile.

The ACT score report will provide more information about test-taking experience in the form of sub score. The higher the score,  you will get into the colleges of your choice.

The maximum ACT score is not at the 100th percentile. because the student cannot score more than himself as well as others whom scored the same.

Although your question lacks some data a general answer have been provided above

       For the maximum score ( 36) to be at the 100th percentile the individual who scores the maximum ACT score, must have scored higher than others and also him/herself in the data set.

Even if a student scores the highest score (36) it does not mean they have scored higher than others who had the same score ( 36 ) with them or him/her self.

Hence we can conclude that the maximum ACT score ( 36 ) cannot be at the 100th percentile because the student cannot score more than himself as well as others whom scored the same.

Answer:

The correct answer is x = 6.

Step-by-step explanation:

To solve this problem, we first must recognize that DE + EF = DF.

From this information, we can set up the following equation when we substitute in the given values:

DE + EF = DF

(4x-1) + 9 = 9x - 22

Our first step is going to be to combine like terms on the left side of the equation.  This is modeled below:

4x - 1 + 9 = 9x - 22

4x + 8 = 9x - 22

Then, we should subtract 4x from both sides of the equation.

8 = 5x - 22

Now, we can add 22 to both sides of the equation.

30 = 5x

Finally, we can divide both sides by 5.

x = 6

Therefore, the correct answer is x = 6.
