Which statement BEST describes why this set of ordered pairs is NOT a function?
{(1, 5),(2, 6),(3, 6),(4, 1),(4, 20),(5, 21),(6, 24)}
We have x = 4 repeating itself
If we graph the two points (4,1) and (4,20), then we see the relation fails the vertical line test.
The input x = 4 leads to more than one output y = 1 and y = 20 simultaneously.
This is why we don't have a function.
The given set does not represent the function as one value of [x] has two values of [y] in the coordinates -
(4, 1), (4, 20).
What is a function? What is equation modelling? What is a mathematical equation and expression?In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the functionEquation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given are the coordinates as -
{(1, 5), (2, 6), (3, 6), (4, 1), (4, 20), (5, 21), (6, 24)}
The given set does not represent the function as one value of [x] has two values of [y] in the coordinates -
(4, 1), (4, 20).
Therefore, the given set does not represent the function as one value of [x] has two values of [y] in the coordinates -
(4, 1), (4, 20).

In the data set {(7,7);(3,10);(5,9);(2,12);(0,1);(6,4);(4,10);(8,6)}, which point is a possible outlier? please help :(
Answer: Choice D
(0,1)
==================================================
Explanation:
Plot all of the points on the same xy grid as shown below.
The majority of the points cluster together somewhat. In this cluster we have a downward trend (aka negative correlation). As x gets bigger, y gets smaller, and vice versa.
Highlighted in red is the point (0,1) which is fairly separate from the main cluster of other black points. This is the outlier that will pull the regression line away from the main cluster of points.

How much greater is the median number of pairs of shoes in the inventory at the Golf Pro Shop than the median number of pairs of shoes in the inventory at the Tennis Pro Shop? Enter your answer in the box.
The difference between the median of the golf pro box and tennis pro box is 20.
What is Median?
The median is the middle value of an entire data set. If the number of data points(observations) in the set is odd then the middle value is the median but, for an even number of observations, the median is calculated by finding the means for the two middle data points.
As we know that the vertical line in the box plot is the median. Therefore, the median of the Golf pro shop is 40, while the median of the tennis pro shop is 20.
The difference between the median of the golf pro box and tennis pro box
= 40 - 20
= 20
Hence, the difference between the median of the golf pro box and tennis pro box is 20.

The cost, in dollars, of making x cups of lemonade is x+25. The predicted revenue is 12+2x dollars. Write a polynomial that represents the profit of selling x cups of lemonade. If you sold 20 cups of lemonade, will you make a profit? (yes or no)
Answer:
P = x - 13
Yes, you will make a profit
Step-by-step explanation:
Given;
cost of making x cups, C = x + 25
predicted revenue, R = 12 + 2x
Profit of selling x cups is given by;
P = R - C
P = (12 + 2x) - (x + 25)
P = 12 + 2x - x - 25
P = x - 13
When 20 cups of lemonade are sold, the profit made can be estimated using the profit function above;
P = x - 13
P = 20 - 13
P = 7
Thus, you will make a profit
Which of the following two-dimensional shapes can be rotated to create a cone? Right triangle Square Circle Ellipse.
Refer to the figure below for an example.
Imagine the right triangle acts like a propeller to spin around to carve out the 3D shape of a cone. The axis of rotation is the vertical part of the triangle. In a sense, it's like a revolving door of sorts.
In contrast, a square and rectangle will rotate around to create a cylinder. An ellipse or circle rotates around to form a (squashed) sphere.

Consider the dilation:
(a) Is the image of the dilation a reduction or an enlargement of the original figure? Explain.
(b) What is the scale factor? Explain.
Answer:
Reduction
Why ?
See co-ordinates decreased back in dilated figure .#b
M=(-3,3)M'=(-2,2)S=(6,3)S'=(4,2)V=(3,-3)V'=(2,-2)Scale factor:-
[tex]\\ \rm\rightarrowtail \dfrac{-2}{-3}=\dfrac{4}{6}=\dfrac{2}{3}[/tex]
[tex]\\ \rm\rightarrowtail \dfrac{2}{3}=\dfrac{2}{3}=\dfrac{2}{3}[/tex]
Scale factor=K=2/3Answer:
The original figure is MSV and the dilated figure is M'S'V'
Therefore, the dilation is a reduction of the original figure since the side lengths have reduced in length.
To determine the scale factor, choose one of the sides and compare the length before and after the dilation → let's use MS:
length of MS = 9 units
length of M'S' = 6 units
⇒ scale factor = length after dilation ÷ length before dilation
= 6 ÷ 9
= 2/3
To find the center of dilation, draw a line through each point and its corresponding dilated point. The point at which the 3 lines meet is the center of dilation.
Therefore, the center of dilation for this question is the origin (0, 0)

A square has a perimeter of 100cm What is the length of each side?
Answer:
each side of the square is 25cm
Step-by-step explanation:
this is because of two things:
1. a square has equal sides
2. the perimeter is all the sides added together.
so if you call the length of one side x, you can make this equation:
x + x + x + x = 100
combine like terms
4x = 100
divide both sides by 4
x = 100/4
x = 25
Answer:
25 cm

Answer:
y = 9x + 9
Step-by-step explanation:
so the points are:
(0,9) (1, 18) (2, 27) (3, 36) (4, 45)
since the y intercept is when x is 0 write it in the equation!
y = mx + 9
now to solve for slope
use the equation y2 - y1/ x2 - x1 or y1 - y2/x1 - x2
sooo use (1, 18) and (2, 27)
27 - 18/2 - 1
9 / 1 = 9
y = 9x + 9
check with the points you did not use!
(3, 36)
36 = 9(3) + 9 ?
36 = 27 + 9?

A student in eighth grade notices that the current cost of tuition, books, and fees at a 4 year college is $14,000 per year. The family reads that there is an annual increase of $550 per year. What will the the total cost of tuition, books, and fees for this student when this student attends college for four years, after graduating high school? $63,700 $68,100 $70,300 $72,500.
Answer:
$68,100
Step-by-step explanation:
$14,000 : 9th grade
$14,000 + $550 = $14,550: 10th grade
$14,550 + $550 = $15,100: 11th grade
$15,100 + $550 = $15,650: 12th grade
$15,650 + $550 = $16,200: year 1 of college
16,200 + $550 = $16,750: year 2 of college
$16,750 + $550 = $17,300: year 3 of college
$17,300 + $550 = $17,850: year 4 of college
16,200 + 16,750 + 17,300 + 17,850 = $68,100
Answer:
$68,100
$14,000 + $550 = $14,550: 10th grade
$14,550 + $550 = $15,100: 11th grade
$15,100 + $550 = $15,650: 12th grade
$15,650 + $550 = $16,200: year 1 of college
16,200 + $550 = $16,750: year 2 of college
$16,750 + $550 = $17,300: year 3 of college
$17,300 + $550 = $17,850: year 4 of college

What is the solution to this system of equations?
Answer:
C. Infinite solutions
Step-by-step explanation:
2x+4y=-2
3x+6y=-3
3(2x+4y=-2)
-2(3x+6y=-3)
6x + 12y = -6
-6x - 12y = 6
This is zero, meaning infinite solutions.
Answer:
C
Step-by-step explanation:
Add -4y to both sides
2x+4y-4y=-2-4y
2x=-4y-2
x=-2y-1. Now you substitute this to the second equation.
3(-2y-1)+6y=-3
-6y-3+6y=-3
-3=-3, so now add 3 to both sides
0=0, so infinite solutions.

Points A and B are two of the vertices of a right triangle. They are the endpoints of the hypotenuse AB¯¯¯¯¯ of the triangle. The third vertex of the triangle lies in the first quadrant.
Plot a point at the location of the third vertex.
Answer: (1, 2)
Step-by-step explanation:
There are many possibilities for the third point in the first quadrant
The simplest case is drawing a line parallel to x axis from point A and drawing a line parallel to y axis from point B and see where they intersect
The two lines would be:
y=2, x=1
So the point of intersection is (1,2) and they intersect at right angle hence qualify as a third point
Therefore, one possible location for third point is (1,2)
Answer:
Point (1 , 2)
Step-by-step explanation:
AB will form the hypotenuse and this will be the vertex.
