Answer: x^2 + y^2 + 18y + 81 = 0

Step-by-step explanation:

The equation of a circle with center at the point (0, -9) and radius 9 is given by the following equation:

(x - 0)^2 + (y + 9)^2 = 9^2

This can be simplified to the following:

x^2 + y^2 + 18y + 81 = 0

This is the equation of a circle with center at (0, -9) and radius 9.

The sum of the squares of three consecutive odd number   11, 13, 15 is 515.

What are consecutive numbers ?

Numbers that follow each other continuously in the order from smallest to largest are called consecutive numbers. For example: 1, 2, 3, 4, 5, 6, and so on are consecutive numbers.

Let the second number = x.

so the first number = x-2

the third number = x + 2

according to the question, the sum of the squares of the numbers = 515

so the formula is:

x² + (x-2)² + (x + 2)² = 515

(a-b)² = a² + b² - 2ab

and,

(a+b)² = a² + b² + 2ab

So, let’s apply these to our equation:

x² + x² + 2² -2*2x + x² + 2² + 2*2x = 515

There are three x² and 2*2 = 4 and 2*2x = 4x. Let’s apply all that to the equation,

3x² + 4 - 4x + 4 + 4x = 515

there is a -4x and a +4x, -4x + 4x = 0, so let’s remove that.

3x² + 4 + 4 = 515

3x² + 8 = 515

3x² = 515 - 8

3x² = 507

x² = 507/3

x² = 169

x = √169

√169 (square root(169)) = 13

x = 13

if x = 13, then the first number = 13–2 = 11 and the third number = 13 + 2 = 15

Hence , the sum of the squares of three consecutive odd number   11, 13, 15 is 515.

11*11 + 13*13 + 15*15 = 515

Positive Slope: A slope in which two variables, i.e., variable at x-axis and variable at the y-axis, shows a positive relationship is known as positive slope. In simpler words, a positive slope is one in which the variable x increases with the increase in variable y and/or variable y increases with the increase in variable x.

Negative Slope: A slope in which two variables, i.e., variable at x-axis and variable at the y-axis, shows a negative relationship is known as negative slope. In other words, a negative slope is one in which the variable x increases with the decrease in variable y and/or variable y increases with the decrease in variable x.

A number of absolute values that represent whether a line is steeper or flatter and the direction of the line on the graph are known as a slope or gradient. The slope of a line is fundamental concept in economics and mathematics. It is generally denoted by the letter 'm'. The slope can be calculated by dividing the 'vertical change' with the 'horizontal change' between two distinct points on a line.

There are two main types of slopes which are given below:

Positive Slope: A slope in which two variables, i.e., variable at x-axis and variable at the y-axis, shows a positive relationship is known as positive slope. In simpler words, a positive slope is one in which the variable x increases with the increase in variable y and/or variable y increases with the increase in variable x. Similarly, the variable x decreases with the decrease in variable y, and/or variable y decreases with the decrease in variable x. It means both the variables are complements to each other. A positive slope moves in the upward direction or is upward sloping.

In graphical terms, a positive slope is one in which the line on the graph rises when it moves from left to right. The concept of positive slope can be clearly understood with the help of the supply curve of a producer or firm in economics. The two variables of the curve are price at the y-axis and quantity of goods at the x-axis. Let us assume the firm is producing the goods for profit maximization. Therefore, when the prices of the goods increase, the quantity supplied by the firm of those goods will also increase, while when the prices decrease, the quantity supplied by the firm will decrease.

Negative Slope: A slope in which two variables, i.e., variable at x-axis and variable at the y-axis, shows a negative relationship is known as negative slope. In other words, a negative slope is one in which the variable x increases with the decrease in variable y and/or variable y increases with the decrease in variable x. In the same manner, the variable x decreases with the increase in variable y, and/or variable y decreases with the increase in variable x. This represents an inverse relationship between these two variables. A negative slope moves in the downward direction or is downward sloping.

Graphically, a negative slope is one in which the line on the graph falls when it moves from left to right. One of the best examples of the negative slope of the graph is the demand curve in economics. The two variables of the curve are price at the y-axis and quantity of goods at the x-axis. As we know, the consumers buy a large quantity of a good at a lower price than at a higher price. Therefore, the quantity demanded by the consumers of goods will decrease with an increase in the prices of those goods. On the other hand, when prices of the goods will decrease, the quantity demand will increase.

Answer:

Step-by-step explanation:

You want to know how the form of a linear equation can be used to reveal its key characteristics.

The characteristics of a linear equation that are of interest for this problem are ...

A linear equation can be written in many forms. Some of these forms make it easy to determine one or more of the key characteristic listed above. Some of the more common forms are Slope-Intercept form, Point-Slope form, and Standard form. There are a number of others.

The slope-intercept form is ...

  y = mx + b

where m is the slope, and b is the y-intercept. This form makes it easy to determine ...

This equation cannot be used to describe a vertical line.

We can rearrange the above equation to reveal the x-intercept.

  y = m(x -a)

where m is the slope and 'a' is the x-intercept. This form makes it easy to determine ...

This equation cannot be used to describe a horizontal line (except y=0).

The equation of a line with slope m through point (h, k) can be written as ...

  y -k = m(x -h)

This makes it easy to determine ...

This equation cannot be used to describe a vertical line.

The standard form equation of a line is similar in style to the standard form equations for other geometric figures (circle, ellipse, hyperbola). This form is ...

  Ax +By = C

where A, B, C are mutually prime (integers), and A ≥ 0. If A = 0, then B > 0. That is, the leading coefficient is positive. Integers are preferred for the coefficients, but some lines have irrational slope or other key characteristics, so integers may not be able to be used in all places.

The key characteristics cannot be read from the equation directly, but they are one step away:

Solving for the intercepts is especially easy, so we list this form as one that can be efficient for determining the intercepts.

A very nice form for efficiently determining the intercepts, or efficiently writing an equation from the intercepts is ...

  x/a +y/b = 1

where 'a' is the x-intercept, and 'b' is the y-intercept. This form makes it very easy to determine ...

You may notice that dividing the standard form equation by C and rearranging the coefficients will give you this form:

  Ax +By = C

  (A/C)x +(B/C)y = 1 . . . . . . . divide by C

  x/(C/A) +y/(C/B) = 1 . . . . . . . intercept form

The general form of a polynomial equation of any degree is ...

  f(x, y) = 0

The general form of a linear equation is ...

  Ax +By +C = 0

This is simply a rearrangement of the Standard form equation. Equations written in this form can be helpful for ...

When two points are given, and you want an equation of the line, various forms are available for using those coordinates. These forms make use of the fact that the slope of a line is the same everywhere, so the ratio of any difference of y-coordinates to the corresponding difference of x-coordinates is a constant (the slope). Again, slopes of 0 or "undefined" can cause trouble with certain of these forms. Here are several different arrangements of 2-point forms:

  [tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\(x_2-x_1)(y-y_1)=(y_2-y_1)(x-x_1)\\\\\dfrac{y-y_1}{x-x_1}=\dfrac{y_2-y_1}{x_2-x_1}=m\qquad\text{Slope form}\\\\\\\dfrac{x-x_1}{y-y_1}=\dfrac{x_2-x_1}{y_2-y_1}\qquad\text{inverted from the above}\\\\\\\dfrac{y-y_1}{y_2-y_1}=\dfrac{x-x_1}{x_2-x_1}[/tex]

The last three "ratio forms" are variations of each other. Any such proportion can be written 4 ways. (3 are shown) The form not shown has the variables in the denominator, which is usually not useful.

All of these forms can be written in a "general form" by subtracting one side.

The slope can be read directly from the 1st and 3rd of the forms shown here. It is m = (y2-y1)/(x2-x1).

The slope form is useful for determining ...

Another 2-point form is one written as a determinant:

  [tex]\left|\begin{array}{cc}x-x_1&x_2-x_1\\y-y_1&y_2-y_1\end{array}\right|=0[/tex]

__

Additional comment

It can be useful to recognize the various forms and their relationship to known points on the line or other key characteristics of the function. Any of the slope or point-slope forms make it easy to write the equations of parallel or perpendicular lines through a given point. (The standard and general forms can be used for this, too.)

A unique kind of sequence is a geometric sequence. Every term in the series (aside from the first term) is multiplied by a fixed amount to determine the following term. In other words, we multiply the current phrase in the geometric sequence by a constant term (called the common ratio), and then divide the current term in the geometric sequence by the same common ratio to discover the previous term in the geometric sequence.

Every term in a geometric series is obtained by multiplying the term before it by the same number. [tex]a_{n}=a_{1} r^{n-1}[/tex] is the general phrase for it. The common ratio is denoted by the number r. Any term in the sequence can be used to find it by dividing it by the word before it.

The triangle transitive congruent is proved by considering that if one triangle is congruent to second triangle and second triangle is congruent to third one, then the first triangle is congruent to third triangle.

The transitive property states that if one geometry is congruent with another, and the second is congruent with a third, then the first is also congruent with the third.

Statement : If triangle ABC is similar to triangle PQR and triangle PQR is similar to triangle EFG , then triangle ABC is similar to triangle EFG.

Given, ∆ABC ≅ ∆PQR and ∆PQR ≅ ∆EFG

RTP -> ∆ABC ≅ ∆EFG.

Proof : ∆ABC ≅ ∆PQR, SSA Congruence which implies, AB = PQ --(1)

PR = AC --(2)

and angle ABC = angle PQR --(3)

∆PQR ≅ ∆EFG, AAS Congruence which gives

Angle PQR = Angle EFG --(4)

PQ = EF --(5)

Angle PRQ = Angle EGF --(6)

from (3) and (4) we get,

angle ABC = Angle EFG --(7)

from (1) and (5) we get , AB = EF --(8)

angle BAC = angle FEG = 40° --(9)

Now, from (7) , (8), (9) we conclude that the triangle ABC is Congruent to triangle EFG by ASA Congrauance postulate i.e ∆ABC ≅ ∆EFG.
