What is coordinate plane ?Two number lines combine to form a two-dimensional surface known as a coordinate plane. It is created when the origin, a point where the X- and Y-axes coincide, is crossed by a horizontal line. Points are located using the numbers on a coordinate grid. You can graph points, lines, and many other things using a coordinate plane. It serves as a map and provides clear directions between two points.The following is a definition of a coordinate plane: The intersection of the Y-axis, a vertical line, and the X-axis, a horizontal line, creates a coordinate plane, also referred to as a rectangular coordinate plane grid.

who can solve this equation 4x-6=x+9 ??
Answers
Answer:
x = 5
Step-by-step explanation:
Hello!
According to the question, what's the value of 4x-6=x+9
4x-6=x+9
Collect like terms
x - 4x = -6 - 9
-3x = -15
Divide both sides by the coefficient of x which is -3
-3x/-3 = -15/-3
x = 5
When checking
4x-6=x+9
(4)(5)−6 = 5+9
14=14
True
We bring the x to 4x to easily solve it.As it was positive on the left side,it becomes negative on the right side and we bring the -6 on the right side to the left side to give 6.
This will make an answer of 3x=15
As we are finding the value of x alone,we divide both side by the coefficient of the variable which is 3 on both side to make x alone.3x/3 will give x while 15/3 will give 5.
THEREFORE X=5

Demonstrating that the limit doesn't exist
What is Limits?
The value that a function approaches when the input approaches a certain value is known as a limit. Calculus and mathematical analysis are not possible without limits, which are used to define continuity, derivatives, and integrals.
The limit exists only if the value of the limit along every direction that leads to (1,1) is same.
So by calculating,
lim xy -x-y + 1 / x^2 + y^2 - 2x - 2y + 2
x->1
calculating the limit along the line x = 1
Similarly,
lim xy -x-y + 1 / x^2 + y^2 - 2x - 2y + 2
x->1
calculating the limit along the line y = 1
And the last limit you calculated is along line y=x.
To answer your question, the calculation of the limit along y=1 would not have been necessary. It is sufficient to demonstrate the absence of a limit by giving just two cases in which it appears to vary along several directions.

Volume is 10x3 + 67x2 + 30x − 72, length is 5x − 4, width is 2x + 3
Answers
Answer:
height = x + 6
Step-by-step explanation:
Volume = length x width x height
V = 10x³ + 67x² + 30x − 72
length = 5x - 4 and width = 2x + 3
So length x width = (5x - 4 ) x (2x + 3)
Using the FOIL method:
= (5x)(2x) + (5x)(3) + (-4)(2x) + (-4)(3)
= 10x² + 15x - 8x - 12
= 10x² + 7x -12
So to find height, divide Volume by (length x width)
10x³ + 67x² + 30x − 72 ÷ 10x² + 7x -12
Use polynomial long division. See image ( I did the best I could to capture the process)
The answer is x + 6
To verify
Multiply (5x-4) (2x + 3) (x + 6) = 10x³ + 67x² + 30x − 72

7. Jill was 80th in a class of 200, whereas Nathan, who is in the same class, has a percentile rank of 80. Which student has the higher standing in the class?
Answers
The student that has the higher standing in the class is Jill
How to determine the student that has the higher standing in the class?The given parameters are:
Number of students = 200
Jill's position =80th
Nathan's position = Percentile rank of 80
The above means that
Nathan's position = 80 percentage of the number of students in the class
Substitute the known values in the above equation
So, we have the following equation
Nathan's position = 80 percentage of 200
Rewrite as
Nathan's position = 80 percentage * 200
Express as percentage
Nathan's position = 80% * 200
Express 80% as decimal
Nathan's position = 0.80 * 200
Evaluate the product
Nathan's position = 160
So, we have
Jill's position =80th
Nathan's position = 160th
By comparing the positions, 80th is greater than 160th
Hence, Jill has the higher standing in the class

Scale factor means ratio of the sides of the triangle then the measures of the indicated sides, and the scale factor of CB and AB exists ΔDEF - ΔABC; x = 1.5; CB = 3.9; AB = 3.
What is meant by scale factor?A scale factor is the amount by which an object is multiplied to produce a second object of different size but with the same appearance. The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).
Each pair of given polygons are similar.
Similarity statement for the given polygons:
In ΔDEF and ΔABC,
∠D = ∠A (Angle)
∠E = ∠B (Angle)
Therefore, ΔDEF ΔABC (by AA similarity)
If two triangles are similar, then their sides are proportional.
[tex]$\Rightarrow \frac{D F}{A C}=\frac{D E}{A B}$[/tex]
[tex]$\Rightarrow \frac{2.4}{3.6}=\frac{2}{2 x}$[/tex]
By using cross multiplication, we get
⇒ 2.4 × 2x = 2 × 3.6
simplifying the above equation, we get
⇒ 4.8x = 7.2
⇒ x = 1.5
Therefore, the value of x = 1.5.
Substitute x = 1.5 in CB and AB,
CB = 3x – 0.6 = 3(1.5) – 0.6 = 3.9
AB = 2x = 2(1.5) = 3
Scale factor means ratio of the sides of the triangle.
⇒ DF/AC = 2.4/3.6 = 2/3
Therefore, the correct answer is option a) ΔDEF - ΔABC; x = 1.5; CB = 3.9; AB = 3.

Substitute the known values in the above equation
So, we have the following equation
-2x + 4 = 2x - 8
Collect the like terms in the above equation
So, we have
2x + 2x = 8 + 4
Evaluate the like terms in the above equation
So, we have

By solving the equation, we get the cost of sheet metal =$20 per sq. feet
What is an equation?
An equation is a formula in mathematics that expresses the equivalence of two expressions by linking them with the equals symbol =. The word equation and its cognates in various languages may have somewhat different definitions; for example, in French, an équation is defined as including one or more variables, but in English, an equation is any well-formed formula consisting of two expressions linked by an equals sign. Solving an equation with variables entails finding which variables' values make the equality true. The variables for which the equation must be solved are also known as unknowns, and the values of the unknowns that fulfill the equality are known as equation solutions. Identity equations and conditional equations are the two types of equations.
Given equation 8.2x-3.7x = 90
or, 4.5x = 90
or, x = 90/4.5 = 20

The difference of the values is -12.9 while the product of the expression is 45.9
How to solve for the differenceWe have to solve for
2.4 x 10/8
= 2.4 x 1.25
= 3
(9.2 x 10/6)
= 9.2 x 1.667
= 15.3
The difference between the values wpuld be
3 - 15.3
= -12.3
The product of the expressions would be solved by

Step-by-step explanation:
Formula: P (n,r) = n! ÷ (n - r)!
n = Total number of objects in a set
r = The number of items you choose
!/Factorial = Product of all positive numbers less than or equal to the given positive number
9! = 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9
7! = 1 x 2 x 3 x 4 x 5 x 6 x 7
P (9,2) = 9! ÷ (9-2)!
362,880 ÷ 5,040 = 72
