A function is a set of relation without repetitive domain. That means we cannot have the same value of x in a set.
Example
{(1,1),(1,2),(2,4),(3,9)}
This is not a function because the relation has same two x = 1 which does not make it a function.
{(1,1),(2,4),(3,9)}
This is a function because there are no same x-values or repetitive domain in a single set.
Back to the question, we can find which table represent a function by looking at the x-value table. If there are two same or more x-values, it is not a function.
AnswerThe answer is the left bottom table as the other table have two same x-values.
HELLLLLLLLPPPPPPPPPPPP,

A pet store has 8 cats. Here are their weights (in pounds).
6, 14, 5, 8, 11, 10, 5, 10
Find the mean weight of these cats.
If necessary, round your answer to the nearest tenth.
Answer:
The mean is 8.6
Step-by-step explanation:
You want to add all of the weight together, then you want to divide that number by how many cats there were.

Jenny bought 7 pounds of strawberries.
They were on sale for
$1.12 for every 2 pounds.
How much did Jenny pay?
Well every 2 pounds is 1.12 so if we take 1.12/2 we get 0.56 and then we have 1.12x3 for the 6 and that is 3.36 so if we add 0.56+3.36 we get 3.92 I HOPEE THIS IS RIGHT DONT COME AT ME IF WRONG

y =
x +
Answer:
[tex]y = 7x [/tex]
Step-by-step explanation:
To find the slope, which is
[tex] \frac{rise}{run} [/tex]
find how high up the y value goes before it intersects the x line at a specific point. It seems that they intersect at (70,10) which would be 70/10 or 7/1. 7/1 is just 7 so the slope of it is just that, 7. As for finding B, look at where the line starts, of it's above or below 0, then you would add or subtract whatever number it starts at (subtract for negative, add for positive). In this case it seems that the intercept is right at 0 so you would neither add or subtract anything. :)

y = 5x - 6&y= -4x + 3
Use the Equal Values Method to solve for x and y
Answer: x = 1 and y = -1
Step-by-step explanation:
Since both equations are equal to y, that means the equations are both equal to each other
5x - 6 = -4x + 3
Solve for x how you would traditionally do it with any other one-variable equation
9x = 9
x = 1
Plug the now known x value into either equation and you will get your y value.
5(1) - 6 = -1
-4(1) + 3 = -1

Which polynomial function could be represented by the graph below?
On a coordinate plane, a parabola opens up. It goes through (2, 0), has a vertex at (3, negative 3), and goes through (4, 0).
Answer:
f(x) = 3(x - 3)^2 - 3Step-by-step explanation:
Let the base function be
f(x) = ax^2It has the vertex at (3, -3), so it is translated 3 units right and 3 units down:
f(x) = a(x - 3)^2 - 3It has zero's at (2, 0) and (4, 0)
Substitute and solve for a:
a(x - 3)^2 - 3 = 0a(2 - 3)^2 = 3a = 3or
a(4 - 3)^2 - 3 = 0a = 3So the function is:
f(x) = 3(x - 3)^2 - 3See the attached
Answer:
f(x) = 3x2 – 18x + 24

Step-by-step explanation:
4(m+2) = -4(m-2)
by dividing over 4 :
m+2 = -1(m-2)
= m+2 = -m+2
by subtracting 2 :
m = -m
by adding "m" :
2m = 0
So
m = 0

20y-10x=5 in slope intercept form can you explain the steps
Given:
The equation is
[tex]20y-10x+5[/tex]
To find:
The slope intercept form of the given equation.
Solution:
The slope intercept form of a linear equation is
[tex]y=mx+b[/tex]
Where, m is slope and b is the y-intercept.
We have,
[tex]20y-10x=5[/tex]
We need to isolate y. Add 10x on both sides.
[tex]20y-10x+10x=5+10x[/tex]
[tex]20y=5+10x[/tex]
Divide both sides by 20.
[tex]\dfrac{20y}{20}=\dfrac{5+10x}{20}[/tex]
[tex]y=\dfrac{5}{20}+\dfrac{10x}{20}[/tex]
[tex]y=\dfrac{1}{4}+\dfrac{x}{2}[/tex]
[tex]y=\dfrac{1}{2}x+\dfrac{1}{4}[/tex]
Therefore, the slope intercept form of the given equation is [tex]y=\dfrac{1}{2}x+\dfrac{1}{4}[/tex].
Sally puts $2,500 in a bank account. She takes it out 10 years later and with interest, now has $4,100. What is the percent change?
Answer:
64%
Step-by-step explanation:
Find the percent change by finding the difference between the amounts, then dividing it by the original amount
(4,100 - 2,500) / 2,500
1600 / 2500
= 0.64
So, the percent change is 64%
Which of the following are equivalent to 9x - 27?
Select ALL that apply.
9(x - 3)
3(3x - 9)
x(9x - 3)
3(3x - 7)
3(x - 9)
Answer:
1) 9(x - 3) = 9x - 27. So, 1) applies.
2) 3(3x - 9) = 9x - 27. So, 2) applies.
3) x(9x - 3) = 9[tex]x^{2}[/tex] - 3x. So, 3) dosn't apply.
4) 3(3x - 7) = 9x - 21. S0, 4) dosn't apply.
5) 3(x - 9) = 3x - 27. So, 5) also dosn't apply.
Step-by-step explanation:
1) 9(x - 3) = 9x - 27. So, 1) applies.
2) 3(3x - 9) = 9x - 27. So, 2) applies.
3) x(9x - 3) = 9[tex]x^{2}[/tex] - 3x. So, 3) dosn't apply.
4) 3(3x - 7) = 9x - 21. S0, 4) dosn't apply.
5) 3(x - 9) = 3x - 27. So, 5) also dosn't apply.
The expressions that are equivalent to 9x - 27 are:
9(x - 3)
3(3x - 9)
To determine which expressions are equivalent to 9x - 27, let's simplify each of the given options:
9(x - 3):
Expanding the expression, we get 9x - 27.
This expression is equivalent to 9x - 27.
3(3x - 9):
Expanding the expression, we get 9x - 27.
This expression is equivalent to 9x - 27.
x(9x - 3):
Expanding the expression, we get 9x² - 3x.
This expression is NOT equivalent to 9x - 27.
3(3x - 7):
Expanding the expression, we get 9x - 21.
This expression is NOT equivalent to 9x - 27.
3(x - 9):
Expanding the expression, we get 3x - 27.
This expression is NOT equivalent to 9x - 27.
Therefore, the expressions that are equivalent to 9x - 27 are:
9(x - 3)
3(3x - 9)
So, the correct options are 1 and 2.
