It should be noted that when multiplying powers you add rather than multiply the exponents in order to give an accurate value as multiplication do powers means the addition of the powers.

Exponentiation is a mathematical process that involves the base b and the exponent or power n. It is represented as bⁿ and is pronounced as "b to the n."

Algebra is the study of mathematical symbols, and logic is the manipulation of those symbols.

For example 3⁴ × 3² will be 3^6 rather than 3^8.

In the picture, There is graph with a triangle SNZ. The reflected triangle of y=3 as (1,2),(5,3) and (5,5).

Given that,

In the picture, There is graph with a triangle.

The triangle is SNZ.

We have to find the reflection across y=3.

We have to draw a line on y=3.

On the line y=3,

Z point is there so it will be same that is (5,3).

Now, the point S is on (5,1)

Here, y is 1 that is 3+2=5

So, we take the reflected S point as (5,5)

Now, the point N is on (1,4)

Here, y is 4 that is 3-1=2

So, we take the reflected N point as (1,2).

Therefore, we get the reflected triangle of y=3 as (1,2),(5,3) and (5,5).

Answer:

815/99 (fraction); 8 23/99 (mixed number)

Step-by-step explanation:

the fraction for 0.23 repeating is 23/99

you add 8 in front of it

8 23/99 is the mixed number version

for the fraction version you must multiply 99 to 8 and then add it to 23

8 * 99 = 792

792 + 23 = 815

so

the fraction is 815/99

The length of the actual schoolyard given the scale is 144 meters

A scale drawing is either an enlarged or reduced image of another image or object. A scale drawing is enlarged or reduced using a scale. The scale drawing is usually reduced at a constant dimension using a scale. A scale is the ratio of the dimensions of the scale drawing and the dimensions of the original image.

Length of the actual schoolyard = (length of the school yard x scale of the schoolyard) / scale of the drawing

(324 x 4) / 9 = 144 meters

The solution of the equation −46x + 874 = 86 − x will be 17.51 which is that number.

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

−46 times a number minus 19 is equal to 86 less than the number.

Let the number be x. Then the equation is given as,

−46(x − 19) = 86 − x

Simplify the equation, then we have

−46x + 874 = 86 − x

45x = 788

x = 788 / 45

x = 17.51

The solution of the equation −46x + 874 = 86 − x will be 17.51 which is that number.

Sheila's mapping diagram doesn't represent a function because it includes the points (3, 6) and (3, 6) and fails the vertical line test.

An illustration of two circles that depicts the relationship between input and output values is known as a mapping diagram. By drawing an arrow from one x-value to its corresponding y-value, the x-values (inputs) in the image are transferred to the y-values (outputs).

It does not represent a function because the same input value, 3, is mapped to more than one output value, 3 and 6. Her relation has the following ordered pairs: (1, 1), (2, 2), (3, 3), (3, 6), (4, 4), 5, 5), and (6, 6). Since both (3, 3) and (3, 6) have the same x-coordinate, the relation fails the vertical line test and is not a function.

Answer:

  2x +y = 1

Step-by-step explanation:

You want the equation of a line parallel to 2x+y=4 through point (-1, 3).

A parallel line will have the same slope, which is a function of the ratio of the x- and y-coefficients. Hence, the equation of the parallel line can use the same coefficients. It will have a constant suitable for the given point.

  given: 2x +y = 4

  parallel: 2x +y = c

  through point (-1, 3): 2x +y = 2(-1) +(3) = 1

The equation of the parallel line is 2x+y = 1.

The thing that is wrong with the bookkeeper’s entry assuming Karlin uses the allowance method is that the company uses allowance method and thus the write-off entry would not be to bad debt account.

How yo illustrate the information?

It should be noted that because the business is using the allowance approach in this instance, the write-off entry would not be to the account for bad debts. To write off an account, a debit must be made to a separate account that is kept as an allowance for dubious accounts.

Since the receivables would not be collected, the accounts receivable account would be credited. In this case,the write off isn't appropriately illustrated in the account.

A matrix is a rectangular array or table where data is organized into rows and columns, and "matrixes" is the plural version of matrix. It doesn't matter how many columns and rows they have. Matrices can be used for a variety of operations, including addition, multiplication, transposition, and scalar multiplication. When executing these matrix operations, certain guidelines must be followed. For example, matrices can be added to or subtracted from if only their rows and columns are the same, whereas they can be multiplied if only their first and second sets of columns are exactly the same.

A =[tex]\left[\begin{array}{ccc}1&-2&0\\-5&8&2\\0&4&1\end{array}\right] \left[\begin{array}{ccc}X\\Y\\Z\end{array}\right] =\left[\begin{array}{ccc}1\\4\\5\end{array}\right][/tex]

We have that the following two points lie on the line:

• (-2, 0) and (4, 6)

And we need to find the equation of the line that passes through both points.

To find the equation of the line, we can proceed as follows:

1. Apply the two-point equation of the line, which is given by:

2. We have to label both points as follows:

• (-2, 0) ---> x1 = -2, y1 = 0

• (4, 6) ---> x2 = 4, y2 = 6

3. Now, we can substitute the corresponding points into the two-point equation of the line:

Therefore, we have that the slope of the line is m = 1, and the equation of the line is y = x + 2.

Therefore, in summary, the equation of the line is y = x + 2 (Option D).
