Answer:
The element 15 has two arrows pointing to both 7 and 9. This is a clear violation of the requirement to be a function. A function is well behaved, that is, each element in the domain must point to one element in the range. Therefore, this relation is not a function.

The midpoint of \overline{\text{AB}}
AB
is M(3, -2)M(3,−2). If the coordinates of AA are (8, 4)(8,4), what are the coordinates of BB?
Answer:
Step-by-step explanation: I am trying to interpret the question: I'll assume:
Line AB has a midpoint, M.
A is (8,4)
B is unknown, but desired
M is (3,-2)
We'll assume a straight line of the form y=mx+b, where m is the slope. m can be calculated by the "Rise" over the "Run" between the points A and M:
Rise = (4-(-2))=6
Run = (8-3)=5
Slope = (Rise/Run) = (6/5)
The line becomes y=(6/5)x+b
Calculate b, the y-intercept (the value of y when x is 0), by entering one of the two known points. I'll choose (8,4).
y=(6/5)x+b
4 = (6/5)(8)+b
b = 4 - (6/5)(8)
b = 4 - (48/5)
b = 4 - (9 3/5) or -5 3/5
The equation becomes:
y=(6/5)x - 5 3/5
Point B will have an x value of -2 [The change in x from A to M was (3-8) = -5. From M to 5 would be another -5 increment, so x goes from 3 to (3-5) or -2.
Find the value of y for x=-2:
y=(6/5)x - 5 3/5
y=(6/5)*(-2) - 5 3/5
y=(-12/5) - (28/5)
y = -(40/5) or - 8
B has coordinates of (-2, -8)
If coordinates of point A is (8, 4), then the coordinate of point B will be (-2, -8).
The "Midpoint-Formula" is used to find the coordinates of a point that lies exactly halfway between two given points. It's given as :Midpoint (M) = ((x₁ + x₂)/2, (y₁ + y₂)/2),
In this case, we have the midpoint as M(3, -2) and one of the endpoints as A(8, 4). We need to find coordinates of other endpoint which is B,
Using the midpoint formula, we rearrange it to solve for the missing coordinates (x₂, y₂),
x₂ = 2 × Mₓ - x₁,
y₂ = 2 × [tex]M_{y}[/tex] - y₁,
Substitute the given values:
We have : Mₓ = 3; [tex]M_{y}[/tex] = -2,
x₁ = 8; y₁ = 4
x₂ = 2 × 3 - 8 = -2; y₂ = 2 × -2 - 4 = -8,
Therefore, the coordinates of point-B is(-2, -8).

Answer:
<1 = 58 , <2 = 122, <3 = 58
Step-by-step explanation:
concept #1: a straight line has an angle of 180.
180 -122 = 58
concept #2: a angle across from another(in which they share a common point made by two lines crossing each other) have essentially the same angle degree
<2 = 122
there <3 is also angle degree of <1 which is 58

17. The sum of a three-digit number
and a one-digit number is 642.
The product of the numbers is
5,072. What are the numbers?
Answer: 2 and 321 or 3 and 214
Step-by-step explanation:
One number is between 200-225.
Now, back up just a bit. The product of the two numbers is 642. Product comes from multiplying the two numbers. So, if we divide 642 by the number that is between 200-225, we will get the other number.
So, divide 200 into 642 and get 3 with a remainder of 42
divide 225 into 642 and get 2 with a remainder of 192
This means that the other number must be either 2 or 3. (note: this is because dividing by 200 gives the biggest value it could be and dividing by 225 gives the lowest value it could be -- think about sharing a bag of candy, dividing it between 2 friends gets each person the most candy and dividing it between more friends (3) gives each person less candy).
Well. if the other number is either 2 or 3, and the product of the two numbers is 642, the numbers must be either: 2 and 321 or 3 and 214

evelin had 1/4 of piece of choclate leftover. she wanted to share it which n other people. if each other person got 1/12 of a piece of choclate, how many people did she share with ?
Answer:
2 other people.
Step-by-step explanation:
First, find a common denominator. Note that what you do to the denominator, you must do to the numerator:
[tex]\frac{1}{4} * \frac{3}{3} = \frac{3}{12}[/tex]
Each other person implies that she will reserve a piece of chocolate for herself, so you will subtract 1:
[tex]\frac{3}{12} - \frac{1}{12} = \frac{2}{12}[/tex]
She will share with 2 other people.

QUESTION 10
When looking at her grades, Susan found that she scored a combined 258 points on her first three tests. She also noticed that on tests two and three, she
scored 10 points fewer than the test before.
Write an equation that fits this problem.
Answer:
let the grade points be a,b,c
a+b+c=258
b=c+10( since she noticed that on tests two and three,she scored 10 points fewer).
Answer:
See belowStep-by-step explanation:
Let the first test score is x, then the next two are x - 10 and x - 20 and the total of three is 258.
We can reflect this as:
x + x - 10 + x - 20 = 258Solving we get:
3x - 30 = 2583x = 258 + 303x = 288x = 288/3x = 96The scores are: 96, 86 and 76

Answer:
The answer is -2.25
Answer:
-2.25
Step-by-step explanation:
1. Between each integer, there are four sections. That means that each section is 1/4, or 0.25
2. Starting at -2, we're going to the left by 0.25 to point B. This can be written as an equation of: [tex]-2 - 0.25 = B[/tex]
3. Now, since -2.25 is the result when subtracting 0.25 from -2, -2.25 is the decimal value positioned at point B.

Given the following:
Scale of map: 6 cm represents 8 kmRequired:
Actual distance that 8 cm on the map represents.
We would apply our knowledge of proportion to solve this problem as follows:

In a statewide lottery, one can buy a ticket for $1. With probability .0000001, one wins a million dollars ($1,000,000), and with probability .9999999 one wins nothing ($0). Let Y denote the winnings from buying one ticket. Construct the probability distribution for Y. Show that the mean of the distribution equals .10, corresponding to an expected return of 10 cents for the dollar paid.
Using the expected value, it is found that the mean of the distribution equals $0.1.
The expected value, which is the mean of the distribution, is given by each outcome multiplied by it's probability.
The probabilities of each outcome are:
.0000001 probability of earning $1,000,000..9999999 probability of earning $0.Thus, the mean is given by:
[tex]E(Y) = 0.0000001(1000000) + 0.9999999(0) = 0.1[/tex]
Thus showing that the expected value is $0.1.
