If the x-value repeats and the y does not, is it a function?
Answer:
If X repeats and y does not it is not an example of a function. But if the y repeats and has two different x values that can be known as a function.
For an example ( 1 , 3) and (1, 4) thats not an example of a function because the x value is repeating but if its ( 1, 4) and (2,4) a thats
a function because no x value is repeating the x value is known as an independent value. Does that make sense?
"This relation is definitely a function because every x-value is unique and is associated with only one value of y. So for a quick summary, if you see any duplicates or repetitions in the x-values, the relation is not a function."
If an x-value in a relation repeats, the y-value must also repeat for that x-value to make the relation to be defined as a function.
For a relation to be called a function, the following holds true:
Each x-value (input) has it's own unique y-value (output).
A x-value cannot give two different y-values.
If an x-value repeats, the corresponding y-value must repeat.
Therefore, if the x-value in a relation repeats, the y-value must also repeat for that x-value for the relation to be defined as a function.

1/3 of 2 feet equals blank inches
Answer:
Step-by-step explanation:
The distance d in inches (″) is equal to the distance d in feet (ft) times 12:
USE THIS FORMULAE
d(″) = d(ft) × 12
Answer:
8 inches
Step-by-step explanation:
1 ft = 12 inches so 2 feet would be 24 inches. 1/3 of that is 8 inches.
If f(x)=x^3-x, what is the average of change of f(x) over the interval [1,5]
Given:
The function is:
[tex]f(x)=x^3-x[/tex]
To find:
The average of change of f(x) over the interval [1,5].
Solution:
We have,
[tex]f(x)=x^3-x[/tex]
At x=1, we have
[tex]f(1)=(1)^3-(1)[/tex]
[tex]f(1)=1-1[/tex]
[tex]f(1)=0[/tex]
At x=5, we have
[tex]f(5)=(5)^3-(5)[/tex]
[tex]f(5)=125-5[/tex]
[tex]f(5)=120[/tex]
The average of change of f(x) over the interval [a,b] is
[tex]m=\dfrac{f(b)-f(a)}{b-a}[/tex]
Now, the average of change of f(x) over the interval [1,5] is
[tex]m=\dfrac{f(5)-f(1)}{5-1}[/tex]
[tex]m=\dfrac{120-0}{4}[/tex]
[tex]m=\dfrac{120}{4}[/tex]
[tex]m=30[/tex]
Therefore, the average of change of f(x) over the interval [1,5] is 30.

Which set of coordinates satisfies the system of equations y = x − 3 and y = -2x + 1?
Given:
The system of equations is
[tex]y=x-3[/tex] ...(i)
[tex]y=-2x+1[/tex] ...(ii)
To find:
The set of coordinates that satisfies the system of equations.
Solution:
On equating the given equations, we get
[tex]x-3=-2x+1[/tex]
[tex]x+2x=3+1[/tex]
[tex]3x=4[/tex]
Divide both sides by 3.
[tex]x=\dfrac{4}{3}[/tex]
Putting [tex]x=\dfrac{4}{3}[/tex] in (i), we get
[tex]y=\dfrac{4}{3}-3[/tex]
[tex]y=\dfrac{4-9}{3}[/tex]
[tex]y=\dfrac{-5}{3}[/tex]
Therefore, the required set of coordinates that satisfies the given system of equations is [tex]\left(\dfrac{4}{3},\dfrac{-5}{3}\right)[/tex].

Step-by-step explanation:
The correct answer is option A
What is a reflection?Reflection is the mirror image of the shape. In other words reflection is also called a flip.
How to find which triangle which triangle is the reflection of triangle 1 over the line y=x?If a triangle is reflected over the line y=x, then the coordinates of the vertices of the triangle gets interchanged.In the given figure the vertices of the triangle are (1,1) , (4,1) and ( 4,3)
So, after reflection over the line y=x,
The vertices of the triangle will be (1,1) , ( 1,4) and (3,4). Clearly, the triangle will be in the first quadrant itselfSo, the correct answer will be option A , where the triangle has the vertices (1,1) , ( 1,4) and (3,4).

a) What type of correlation is shown in diagram A?
b) What type of correlation is shown in diagram B?
c) What type of correlation is shown in diagram C?
Answer:
A = strong negative correlation
B = positive correlation
C = very weak or no correlation
Step-by-step explanation:
Scatter plot A:
A clear linear trend line could be observed having a negative slope ; the nature of the slope gives the nature of the correlation (positive or negative). Since the slope is negative then we have a negative correlation. The linear trend line is almost straight with only few points marginally missing the best fit line. Hence. We can conclude to have a strong negative correlation.
Scatter plot B :
Has a positive slope, and hence a positive correlation. The best fit line miss a few points but the linear trend of the plot is still observable. Hence, we can conclude to having a fairly strong positive correlation.
Scatter plot C :
From the graph, no linear trend can be observed and hence it is fit to say that no correlation exists between the points.

Step-by-step explanation:
Jordan can make 7.111 batches before 3 PM today.
What is division?The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.
Given:
Jordan uses a recipe to make yogurt putty.
He buys a bag of cornstarch containing 128 servings that are 1/8 cups each.
He needs [tex]2\frac{1}{4}[/tex] cups for each batch of yogurt putty.
So, servings are 128 x (1/8)
= 16 cups.
To find the number of batches:
Use division,
16 / ( 9/4)
= 16 x 4/9
= 64 / 9
= 7.111
Therefore, 7.111 batches Jordan can make.
