Answer:
slope = - 3
Step-by-step explanation:
calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (2, 3 ) and (x₂, y₂ ) = (5, - 6 )
m = [tex]\frac{-6-3}{5-2}[/tex] = [tex]\frac{-9}{3}[/tex] = - 3

subtract 2a-3b from b-a
Answer:
Answer: (2a+3b)-(a+b) = a + 2b.
Answer:
-2a² - 3b² + 5ab
Step-by-step explanation:
(b-a) - (2a-3b)
= b(2a-3b) -a(2a-3b)
= 2ab - 3b² - 2a² + 3ab
= -2a² - 3b² + 3ab + 2ab
= -2a² - 3b² + 5ab
Find the equation of the line shown below
Answer:
Below in bold.
Step-by-step explanation:
The slope = rise / run
= 5/10
= 1/2.
General form of the straight line is
y = mx + c where m = the slope and C is the y-intercept
Here m = 1/2. and c = 0
So, the answer is y = 1/2 x.

a concert manager counted 650 ticket receipts the day after a concert. the price for a student ticket was $11.50, and the price for an adult ticket was $13.00. the register confirms that $8,112.50 was taken in. how many student tickets and adult tickets were sold?
Based on the calculations, the number of student tickets and adult tickets that were sold are 225 tickets and 425 tickets respectively.
Given the following data:
Total ticket receipts = 650 tickets.
The price for a student ticket = $11.50.
The price for an adult ticket = $13.00.
Total revenue = $8,112.50.
Let T represent the total ticket.Let S represent price for a student ticket.Let A represent price for an adult ticket.Let R represent the total revenue.What is an expression?An expression can be defined as a mathematical equation which is used to show the relationship existing between two or more variables and numerical quantities.
How many student tickets and adult tickets were sold?In order to determine the number of student tickets and adult tickets that were sold, we would translate the word problem into an algebraic expression as follows:
A + S = 650 ......equation 1.
11.5S + 13A = 8,112.50 ......equation 2.
From eqn. 1, we have:
S = 650 - A ......equation 3.
Substituting eqn. 3 into eqn. 2, we have:
11.5(650 - A) + 13A = 8,112.50
7,475 - 11.5 A + 13A = 8,112.50
1.5A = 8,112.50 - 7,475
1.5A = 637.5
A = 637.5/1.5
A = 425 tickets.
For the student tickets, we have:
S = 650 - A
S = 650 - 425
S = 225 tickets.

What additional information is obtained from an ordinal scale compared to a nominal scale?
An ordinal scale provides more information than a nominal scale since values linked with an ordinal variable will be in natural order, whereas values connected with the nominal variable won't.
Types of Variables:Ordinal variables as well as nominal variables are the two categories of variables listed here. This sort of variable cannot be submitted to the same forms of statistical tests as interval and ratio variables, hence it is crucial to be able to recognize them accurately. Both of these variables fall within the qualitative category. This contrasts with interval as well as rate variables, both of which are categorized as quantitative.
An illustration of an ordinal variable is a Likert scale with words for mood (such as joyful, neutral, or sad). An illustration of a nominal variable is the names of cities in the Canadian province of Alberta.

Which axis is triangle ABC reflected across?
Triangle ABC is reflected across the y-axis. The two congruent triangles are mirrored across the y-axis, thus they are reflected.
6: Give the translation rule, any coordinate point will shift 4 units to the left and rise up 8 units.
What is the translation ruleThe translation rule describes how each coordinate point of the original triangle ABC moves to form the reflected triangle after the reflection across the y-axis.
To reflect a triangle across the y-axis, all you need to do is change the sign of the x-coordinate while keeping the y-coordinate the same. Using this rule, every point on the original triangle ABC will move 4 units to the left and go up 8 units to create the reflected triangle A'B'C' after the reflection.

The area and Perimeter of (ΔABC) are respectively; 17.5 square units and 24.16 units
What is the area and Perimeter of the Triangle?
The formula for the area of a triangle ABC with 3 coordinates is;
Area (ΔABC) = (¹/₂) |x₁(y₂ − y₃) + x₂(y₃ − y₁) + x₃(y₁ − y₂)|
The coordinates are;
(x₁, y₁) = (-6, 6)
(x₂, y₂) = (2, 3)
(x₃, y₃) = (-3, -2)
Thus;
Area (ΔABC) = (¹/₂) |-6(3 − (-2)) + 2(-2 − 6) + -3(3 − 6)|
Area (ΔABC) = (¹/₂)|-30 - 16 + 9|
Area (ΔABC) = ¹/₂ * |-35|
We are taking absolute value and so;
Area (ΔABC) = ¹/₂ * 35
Area (ΔABC) = 17.5 square units
To get the perimeter, we will use distance formula between two coordinates and we have;
AB = 8.544
BC = 7.071
AC = 8.544
Thus;
Perimeter = 2(8.544) + 7.071

a rectangle has a width w and a length that is two more than its width. what is the perimeter of the rectangle? write and simplify an expression. a general expression for the perimeter is (select) . the simplified expression i
The perimeter of the rectangle is 4 + 4w, where w is the width of the rectangle.
In this question,
a rectangle has a width w
Let l be the length of the rectangle.
A length that is two more than its width.
⇒ l = 2 + w
We know that the perimeter of the rectangle is P = 2 × (length + width)
So, for the length l = 2 + w and width w, the perimeter of the rectangle would be,
P = 2 × (w + (2 + w))
We simplify above expression.
P = 2 × (2 + 2w)
P = 4 + 4w
Therefore, the perimeter of the rectangle is 4 + 4w, where w is the width of the rectangle.

Which of the following is not a function? (There may be more than one answer). Explain Clearly.
Answer:
Function A is a function because the inputs on the table do not repeat any number, implying that each input has exactly one output. Function B is not a function because the inputs show that the number 6 is repeated. Function C is not a function because if we make a table, we can see that numbers repeat on the input, so Function C is not a function. Function D is a function because it would pass the vertical line test because no lines overlap with each other or have the input repeating.
Using the function concept, it is found that relations b and c does not represent a function.
When does a relation represents a function?A relation represents a function when each value of the input is mapped to only one value of the output.
On a graph, it means that each value of x is mapped to only one value of y, that is, there are no vertically aligned points on the graph.
For this problem, relation c does not represent a function, as there are multiple values of x are related to two values of y, and there are vertically aligned points on the graph.
In item b, when x = 6, there are two values of y, hence this is also not a function.

Find the angle measures.
J

m21=
m42=
Answer:
m<1 = 111 degrees, m<2 = 69 degrees
Step-by-step explanation:
The measure of angles 1 and 2 are supplementary, (two angles adding up to 180 degrees). Using this, set up the equation:
x + 88 + 3x = 180
4x = 108
x=23 degrees
Next, substitute 23 into the given angles:
m<1 = (23 + 88) = 111 degrees
m<2 = 23 * 3 = 69 degrees
Thus, m<1 = 111 degrees, m<2 = 69 degrees. Hope this helps
Find the axis of symmetry of y=x^2
Answer:
Step-by-step explanation:
x^2 cannot be negative so the minimum value of x^2 is at (0.0)
When x = -1 y = 1 and when x = 1 y = 1
- and so on for all values of x
SO, y = x^2 is symmetrical about the y axis.
and the axis of symmetry is the y axis or we can write it as the line x = 0.
