State the domain and range of the following relation. Is the relation a function?
Answers
Answer:
1: Domain: 2, 4, 3, 6, 2
2: Range: -3, 6, -1, 6, 3
3: Not a function
Explanation:
Domain is x-values aka input value. Range is y-value aka output value. The input value (x) is the first number in the ordered pair and the output value (y) is the second number. For example, say the pair is (4,6) The input value is 4 and output value is 6. We could also say 4 is the Domain and 6 is the Range. In conclusion, x is Domain and range is y.
In order for a set of pairs to be a function, the x values can't be repeated. For example, say the the x values are 3, 6, 7, 4, and 3. Then, this is not a function because there are two 3's that are x values. This only applies for x value (input value) and not y value. There can be multiple of the same y-values aka output value.

I just need help understanding how to calculate for the angles and sides because my teacher is absent when I need help the most. Anything is much appreciated
Answers
Answer:
I will give you the best knowledge I can offer at this moment.
One thing to understand:
- When dealing with angles in a triangle, know that EVERY angle has to add up to 180*. ( * = degrees)
Based on the image provided, I'm assuming that you are learning how to classify triangles based on the angles and side lengths. There are mainly 6 types of triangles:
3 based on sides
3 based on angles
The 3 based on sides
Scalene Triangle
A scalene triangle has all side lengths of different measures. No side will be equal in length to any of the other sides in such a triangle. In a scalene triangle, all the interior angles are also different.
Isosceles Triangle
In an isosceles triangle, the lengths of two of the three sides are equal. So, the angles opposite the equal sides are equal to each other. In other words, an isosceles triangle has two equal sides and two equal angles.
Equilateral Triangle
In an equilateral triangle, all the lengths of the sides are equal. In such a case, each of the interior angles will have a measure of 60 degrees. Since the angles of an equilateral triangle are same, it is also known as an equiangular triangle.
The 3 based on angles
Acute Triangle
An acute triangle is a triangle whose all the three interior angles are acute. In other words, if all interior angles are less than 90 degrees, then it is an acute-angled triangle.
Obtuse Triangle
Obtuse triangles are those in which one of the three interior angles has a measure greater than 90 degrees. In other words, if one of the angles in a triangle is an obtuse angle, then the triangle is called an obtuse-angled triangle.
Right Triangle
A right triangle is a triangle in which one of the angles is 90 degrees. In a right-angled triangle, the side opposite to the right angle (90-degree angle) will be the longest side and is called the hypotenuse. You may come across triangle types with combined names like right isosceles triangle and such, but this only implies that the triangle has two equal sides with one of the interior angles being 90 degrees.

The probability is 1/6 for each side. Each side has a 1/6 chance of getting rolled.
It would be 2/6 if your trying to get either 3 or 6 because there's two sides you can get which would equal 2/6.

The probability of rolling a three or six is 2/6
What is probability?Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we might discuss the likelihood or likelihood of several outcomes.
The ratio of good outcomes to all possible outcomes of an event is known as the probability. The number of positive results for an experiment with 'n' outcomes can be represented by the symbol x. The probability of an occurrence may be calculated using the following formula.
Probability(Event) = Favorable Outcomes/Total Outcomes = x/n
Given:
probability of getting 2= 1/6
probability of getting 6 = 1/6
So, the probability of rolling a three or six
=1/6 + 1/6
=2/6
=1/3
Hence, probability of rolling a three or six is 1/3.

Point p is located in the first quadrant of a coordinate plane.If p is reflected across to form p',choose the four statements that will always be true.
Answers
Answer:
When we do a reflection of a point (x, y) about a given line, the distance between the point (x, y) and the line is invariant under the transformation.
In the case of reflection over x-axis we have:
T (x, y) => (x, -y)
In the case of reflection over the y-axis, we have:
T (x, y) => (-x, y)
Because these two lines are perpendicular, a reflection over the x-axis leaves the distance between the point and the y-axis invariant (and the same for the inverse case)
Then 4 statements that will always be true:
1) The distance between p' and the x-axis is the same as the distance between p and the x-axis.
2) The distance between p' and the y-axis is the same as the distance between p and the y-axis.
From 1 and 2, we get:
3) The distance between p' and the origin is the same as the distance between p and the origin.
4) As we have a reflection, p' can not be in the same quadrant than p, then p' can not lie on the first quadrant.
Which statement describes the system of equations?

Find a formula for the nth term in this
arithmetic sequence:
a1 = -7, 22 = -1, a3 = 5, 24 = 11, ...
Answers
Answer:
[tex]a_n=6n-13[/tex]
Step-by-step explanation:
Arithmetic Sequences
The arithmetic sequences can be identified because each term is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.
The equation to calculate the nth term of an arithmetic sequence is:
[tex]a_n=a_1+(n-1)r[/tex]
Here a1 is the first term and r is the common difference.
The given sequence is:
[tex]a_1=-7, a_2=-1,a_3=5,a_4=11,...[/tex]
We can find the common difference by subtracting successive terms:
[tex]a_2-a_1=-1+7=6[/tex]
[tex]a_3-a_2=5+1=6[/tex]
[tex]a_4-a_3=11-5=6[/tex]
Since all the differences are equal, r=6. Thus, the general term is:
[tex]a_n=-7+6(n-1)[/tex]
Operating:
[tex]a_n=-7+6n-6[/tex]
[tex]a_n=6n-13[/tex]
The nth term is:

Perfume is sold in 2 different sized bottles. The 80ml is priced at £55 and 100ml is £67.50. By finding the the price per ml, determine which one is best value for money.
Answers
Answer:
The best value for money is the perfume that has a 100 ml bottle because the price per ml is lower.
Step-by-step explanation:
To find which one is the best value for money, you need to find the price per ml in each case by dividing the price by the amount of ml:
-80 ml: 55/80=0.687
-100 ml: 67.50/100=0.675
According to this, the answer is that the best value for money is the 100 ml bottle because the price per ml is lower with £0.675 per ml and the 80 ml bottle has a price of £0.687 per ml.

M is the midpoint of LN. If LN = 90, what is LM?
Answers
Answer:
LM = 45
Step-by-step explanation:
M is the midpoint of LN. If LN = 90, what is LM?
L––––––N
From the question
M is the midpoint of LN.
Hence:
L––M––N
Since M is the Midpoint of LN, it means LN is divided in 2 equal parts
LM , MN
So, LM + MN = LN = 90
If LN = 90, LM = 90/2
LM = 45
9. The difference between two numbers is 24. Find the numbers if their
sum is 88.
Answers
Answer:
The numbers are 56 and 32
Step-by-step explanation:
Let the two numbers be x and y
x - y = 24
x = 24 + y --- ( 1 )
x + y = 88 --- ( 2 )
Substitute ( 1 ) into ( 2 ):
24 + y + y = 88
2y = 88 - 24
2y = 64
y = 32
Substitute y = 32 into ( 1 ):
x = 24 + 32
x = 56

The Clark family went out to dinner. If their
dinner bill came to $81.50 and they wish to
leave a 18% tip, how much should they tip?
Answer options. $14.69. $12.45. $10.00
Answers
Answer would be : $14.67
They tipped $14.67
Answer:
$14.69
Step-by-step explanation:
To start with, convert the 18% to a genuine number that can be utilized in a figuring. For percent, this is constantly done by essentially isolating the percent (for this situation 18%) by 100%.So, the conversational term "18%" gets 18%/100% = 0.18 regarding a genuine numerical number.
Second, you have to discover what 18% of your $81.50 feast cost is.This is constantly done by duplicating 0.18 by $81.50, or
0.18 x $81.50=$14.69.
Thus, the measure of tip you will leave is $14.69.
