Answer and Step-by-step explanation: Rotation is a "movement" of a geometric figure in order to transform one in another. In rotation, the shape and size of the figure is the same, so they are congruent.

A geometric figure can be rotated clockwise or counterclockwise and by different angles.

One way to recognized the angle of rotation is comparing the points of the figure and its rotated image.

On the figure below, triangle DOG has coordinates:

D (-2,1)

O (-3,3)

G (1,1)

And its image:

D' (2,-1)

O' (3,-3)

G' (-1,-1)

Comparing both set of coordinates, we observe:

D (-2,1) → D' (2,-1)

O (-3,3) → O' (3,-3)

G (1,1) → G' (-1,-1)

that the coordinates for ΔDOG and ΔD'O'G' are opposite to each other, i.e.:

(x, y) → (-x,-y)

rotating counterclockwise.

Since coordinates are opposite and rotation is counterclockwise, ΔD'O'G' is rotated by 180° related to ΔDOG.

Answer:

[tex]\frac{x^2-4}{x+2} = x-2\\\frac{4x^2-1}{2x+1} = 2x-1[/tex]

Step-by-step explanation:

a) (x2 - 4)/(x + 2)

We can simply use factorization to solve the given question.

Here the first term will be numerator and second term will be denominator.

We will factorize the numerator.

So,

[tex]\frac{x^2-4}{x+2}[/tex]

Using formula, [tex]a^2+b^2 = (a+b)(a-b)[/tex]

[tex]\frac{x^2-4}{x+2}\\= \frac{(x^2)-(2)^2}{x+2}\\=\frac{(x+2)(x-2)}{x+2}\\= x-2[/tex]

b) (4x2 - 1) / (2x + 1)​

We can simply use factorization to solve the given question.

Here the first term will be numerator and second term will be denominator.

We will factorize the numerator.

[tex]\frac{4x^2-1}{2x+1}[/tex]

Using formula, [tex]a^2+b^2 = (a+b)(a-b)[/tex]

[tex]= \frac{(2x)^2-(1)^2}{2x+1}\\=\frac{(2x+1)(2x-1)}{2x+1}\\= 2x-1[/tex]

Hence,

[tex]\frac{x^2-4}{x+2} = x-2\\\frac{4x^2-1}{2x+1} = 2x-1[/tex]

Answer:

4.7 seconds per word

Step-by-step explanation:

11/2.34=4.7

(Im only guessing)

The average speed of Kim is 4.2857 pages per hour.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

Given that,

It took Kim 2 hours 34 minutes to type an 11 page

1 hour = 60 minutes

1 minute = 1/60 hour

34 minutes = 34/60 hour = 0.567 hour

Total hour = 2.567

Now,

Average speed = Number of pages / Number of hour

Average speed = 11/2.567

Average speed = 4.2857 pages per hour.

Hence "The average speed of Kim is 4.2857 pages per hour".

Step-by-step explanation:

x+b+2c - d is account balance after the transaction as an algebraic expression.

An expression is combination of variables, numbers and operators.

Given,

Lizzy has a total of x dollars in her checking account

She makes a deposit of b dollars cash and two checks each worth c dollars.

She would like d dollars in cash from this transaction. She has enough to cover the cash received in her account.

This can be expressed by algebraic expression as below.

x+b+2c - d

Hence x+b+2c - d is account balance after the transaction as an algebraic expression.

Answer:

they are parallel

Step-by-step explanation:

they have the same slope

The lines represents the parallel line.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

y=5/4x +1 and y=5/4x-7

4y= 5x+ 4 and 4y= 5x-7

Now, [tex]a_1[/tex]= 4, [tex]b_1[/tex]= 5,  [tex]c_1[/tex]= 4

[tex]a_2[/tex]= 4, [tex]b_2[/tex]= 5,  [tex]c_2[/tex]= -7

Now, on comparing the ratio we have

[tex]a_1[/tex]/[tex]a_2[/tex] =  [tex]b_1[/tex]/ [tex]b_2[/tex] ≠  [tex]c_1[/tex]/ [tex]c_2[/tex]

The relationship between lines KO and K’O’ is given as Line K'O' = 5*line KO

Transformation is the movement of a point from its initial point to a new location. Types of transformation are reflection, rotation, translation and dilation.

Reflection happens when it is reflected over a line as we see in a mirror. But here the two triangles are not looking as images on  a line.  Hence no reflection

Rotation is keeping the same shape but rotating through a certain angle.

Translation is not right because there is no vertical or horizontal shift to get new triangle.

Dilation is the increase or decrease in size of a figure by a scale factor.

The larger figure was dilated using a scale factor of 5

hence

Line K'O' = 5 * line KO

The relationship between lines KO and K’O’ is given as Line K'O' = 5 * line KO

Answer:

A

Step-by-step explanation:

We have the expression:

[tex]-4ab[/tex]

And we want to find its sign given that a>0 and b<0.

Notice that the expression is already negative since we have -4.

a>0 means that a is positive. Therefore, we can ignore it since it won’t do anything.

b<0 means that b is negative. Therefore, we will have two negatives being multiplied together. Hence, this will make a positive.

Therefore, the sign of our expression will be positive.

We can see this with an example. Let a=1 (1>0) and let b=-1 (-1<0). Then:

[tex]-4(1)(-1)=4[/tex]

So, the sign is positive.

Hence, the answer is A.

Answer:

Tyson's account will have $ 133.90 more than Ariana's account.

Step-by-step explanation:

In Tyson's case, he invests $ 2,500 in an account whose interest rate is 5.75% and is compounded annually. In turn, Ariana invests the same amount and for the same interest, but this is not compounded.

Thus, Ariana, at the end of her 6 years, will have a total amount in her account of $ 3,362.5 (((2,500 x 5.75 / 100) x 6) + 2,500), of which $ 862.5 will correspond to the interest generated.

Instead, Tyson's investment interests will be consolidated annually. Thus, in 6 years, this investment will evolve as follows:

-Year 1 --- 2,500 x 1.0575 = 2,643.75

-Year 2 --- 2,643.75 x 1.0575 = 2,795.76

-Year 3 --- 2,795.76 x 1.0575 = 2,956.52

-Year 4 --- 2,956.52 x 1.0575 = 3,126.52

-Year 5 --- 3,126.52 x 1.0575 = 3,306.29

-Year 6 --- 3,306.29 x 1.0575 = 3,496.40

Thus, at the end of the 6 years, Tyson will have $ 3,496.40 in his account. Thus, Tyson's account will have $ 133.90 more than Ariana's account.

Answer:

constant property of the proportionally proportionate rrrr is ryx

The relation between the cost (y) of x movie tickets is y= 8.5 x.

In general, the term "proportion" refers to a part, share, or amount that is compared to a total.  According to the concept of proportion, two ratios are in proportion when they are equal.

A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.

Given:

Number of Tickets    Cost

    2                            $17.00

    3                            $25.50

    4                            $34.00

    5                            $42.50

As, y=rx

r= y/x

r= 17/2

r= 8.5

again, r= 34/4

r= 8.5

Hence, the relation is y= 8.5 x.
