Answer:

[tex]y=-55x+570\\[/tex]

Step-by-step explanation:

Ah im too lazy to type out everything

The equation for the relationship between the number of pages left and number of hours is y = 555x - 555 * 444.

The relationship between the number of pages left to read (y) and the number of hours (x) can be represented by a linear equation.

Naoya reads at a rate of 555 pages per hour, which means he reads 555 pages in one hour. In 444 hours, he read 555 * 444 pages.

So, the equation for the relationship between the number of pages left and the number of hours is:

y = 555x - 555 * 444

In this equation:

- y represents the number of pages left to read.

- x represents the number of hours.

- 555x represents the number of pages he reads in x hours (555 pages per hour).

- 555 * 444 represents the total number of pages he read in 444 hours.

Answer: 1/2

Answer:

21 / 99

Step-by-step explanation:

You want to get rid of the decimals so

Let x = 0.21212121

then 100x = 21.21212121

then 100x - x = 21

99x = 21

x = 21 / 99

So 0.2121... is equal to 21 / 99

To write the repeating decimal 0.21212121... as a fraction, we can use the method of infinite geometric series. The fraction equivalent of the decimal is 21/99.

To write the repeating decimal 0.21212121... as a fraction, we can use the method of infinite geometric series. Let x = 0.21212121... . Multiplying both sides of the equation by 100 gives 100x = 21.21212121... . Subtracting the original equation from this, we get 99x = 21, which means x = 21/99. Therefore, the decimal 0.21212121... is equal to the fraction 21/99.

Step-by-step explanation:

The absolute value is never a negative.

Ex: What is the absolute value of -37

A. 37

Answer:

T'(2, - 5 )

Step-by-step explanation:

Under a rotation about the origin of 180°

a point (x, y ) → (- x, - y ), thus

T(- 2, 5 ) → T'(2, - 5 )

After a 180-degree rotation about the origin, the coordinates of point T' that is the image of T(-2,5) are (2,-5).

The coordinates of point T' after a rotation of 180 degrees about the origin are found by changing the signs of the original coordinates. The point T(-2,5) will thus be mapped to point T'(2,-5). This is because the 180-degree rotation reverses the direction of both the x and y coordinates. So, if the original point T has coordinates (x, y), then the rotated point T' will be (-x, -y).

The equivalent expression is: B. y = ((z + 4x)) / 7

To find an equation equivalent to 4x + 7y = z, we want to isolate one of the variables (either x or y on one side of the equation.

Let's isolate x in terms of y and z:

Starting with 4x + 7y = z, subtract 7y from both sides:

4x = z - 7y

Now, divide both sides by 4 to solve for x:

[tex]\[x = \frac{z - 7y}{4}\][/tex]

Therefore, the correct choice is option B: [tex]\(x = \frac{z - 7y}{4}\)[/tex].

Complete question:

Which of the following is equivalent to the equation 4x+7y=z ?

A. x=4z-28y

Answer: A rational number is any value that can be expressed as a ratio of two integers. An irrational number is any value that cannot be expressed as a ratio of two integers.

Rational 4 and 1/4

Irrational π and √3

If a number can be written in the form of the fraction of p and q then that number is known as the rational number whereas a number is not written in the form of the fraction p and q then that number is known as the irrational number.

Rational Number - If a number can be written in the form of the fraction of p and q then that number is known as the rational number, that is:

[tex]\rm Rational \;Number = \dfrac{p}{q}[/tex]

Where q is the denominator and p is the numerator.

For example -  [tex]\dfrac{4}{3}[/tex] , [tex]\dfrac{1}{4}[/tex] , etc

Irrational Number - If a number is not written in the form of the fraction p and q then that number is known as the irrational number, that is:

[tex]\rm Irrational \;Number \neq \dfrac{p}{q}[/tex]

Where p is the numerator and q is the denominator.

Domain: {-3,-1,1}

Range: {-1,2,4,5}

The relation Q is described as a list of ordered pairs, shown below.

Q = { (-2, 4), (0, 2), (-1, 3), (4, -2) }

Domain: {-2,-1,0,4}

Range: {-2,2,3,4}

Step-by-step explanation:

Because its the answer

The Domain: {-3,-1,1} and Range: {-1,2,4,5}

Domain – All of the values that go into a relation or a function are called the domain.

Range – All of the entities (output) which emerge from a relation or a function are called the range.

All input values that are used (independent values) forms the Domain set.

All output values that are used (dependent values) forms the Range set.

Example: Given Function:- f = 2x+1 , Find the domain, range if 1<=x<=5.

The values of x lies from 1 to 10.

So, domain is {1, 2, 3, 4, 5}.

The values of f obtained by putting domain elements in the function will be range.

So, range is {3,5,7,9,11}.

We have relation Q as

Q = { (-2, 4), (0, 2), (-1, 3), (4, -2) }

so, we know domain are the input values

Domain: {-2,-1,0,4}

and range are the output values

Range: {-2,2,3,4}
