Step-by-step explanation:
Daniela : nice definition
Ori : part is right, but part is not
Kaori : incorrect
Daniela would not even have to say, that the lines are distinct. in any case, yes if you don't change anything about the appearance of the lines, but can move them on top of each other. and they completely blend in with each other, then yes they are parallel.
Ori is wrong about the part that they have to be close together. the second line could be in another galaxy, but if they are in the same plane and never intersect each other, then they are parallel.
Kaori is wrong by understanding that parallel means to opposite of perpendicular. perpendicular just means that the 2 lines are intersecting each other at a right angle (90°). but they can intersect at any other angle. that makes them not perpendicular, but they still intersect each other. so, they are not parallel.

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.

Solve inequality.
-b/5 ≥ -6
To solve the inequality, multiply both sides by (-5). The solution is b ≤ 30 or (∞, 30]
Tips to solve linear inequalities:
Isolate the variable on one side by using subtraction or addition. Subtraction and addition will not change the inequality.Use division or multiplication to find the solution. Multiplication and division by a positive number will not the inequality. However, if we multiply or divide both sides with a negative number, we need to flip the inequality direction.Interval notation is often used for the solution(s). Recall the differences between a bracket [ or ], and a parenthesis ( or ). A bracket means the endpoint is included in the solution while a parenthesis means the endpoint is not included in the solution. Remember, infinity ∞ always use a parenthesis.
Example: x ≥ 2 can be written as [2, ∞), while
x > 0 is written as (2, ∞)
The given problem:
-b/5 ≥ -6
Notice that the variable, b, is already isolated on the left side. Multiply both sides by (-5) and flip the sign of the inequality ( since we multiply it by a negative number):
-b/5 . (-5) ≤ -6 . (-5)
b ≤ 30
Using the interval notation, the solution is (∞, 30]

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.

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s). Trent wants to buy 2 packs of trading cards for 3 dollars each. The trading card packs that Trent normally buys tend to come in packs of 6, 10, 12, or 15 cards. After selecting 2 packs, Trent found that the first pack of cards cost 25 cents per card, and the second pack cost 30 cents per card. Trent uses this information to write the equations below in order to compare c, the number of cards in each pack. There are cards in the first pack, and there are cards in the second pack. The first pack has more cards than the second pack.
A numerical data is also referred to as a quantitative data and it can be defined as a data set that is primarily expressed in numbers (numerals) only. This ultimately implies that, a numerical data refers to a type of data set consisting of numbers (numerals) rather than words.
Based on the information provided, the number of cards (c) in each pack can be modeled by the following mathematical expression (equation):
Note: 100 cent is equal to 1 dollar.
First pack: 0.25c = 3
Second pack: 0.3c = 3
Now, we can determine the number of cards (c) in the first pack as follows:
0.25c = 3
c = 3/0.25
Number of cards, c = 12 cards.
For the second pack, we have:
0.3c = 3
c = 3/0.3
Number of cards, c = 10 cards.
Therefore, there are 12 cards in the first pack, and there are 10 cards in the second pack.
Difference = First pack - Second pack
Difference = 12 - 10
Difference = 2 cards.
In conclusion, the first pack has 2 more cards than the second pack.

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
Perimeter = 24.16 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.
