Answer:
A
Step-by-step explanation:
We need to find two numbers that have a sum of 5 and a product of 6. These numbers are 2 and 3 so x² + 5x + 6 factored is (x + 2)(x + 3). Since x + 2 is a factor the answer is A.
The binomials below are a factor of A. X+ 2 this trinomial.
What are two binomials?It is easy to remember binomials as bi means 2 and a binomial will have 2 terms. A classic example is the following: 3x + 4 is a binomial and is also a polynomial, and 2a(a+b) 2 is also a binomial (a and b are the binomial factors). The above are both binomials.
What is a trinomial example?A trinomial is an algebraic expression that has three non-zero terms. Examples of a trinomial expression: x + y + z is a trinomial in three variables x, y, and z. 2a2 + 5a + 7 is a trinomial in a single variables a. xy + x + 2y2 is a trinomial in two variables x and y.

During the second day of the school fair, Talia and Yoshi recorded 43 winners out of a total of 324 players. How does the actual number of winners compare to the expected number of winners?
Theorical probability
P ( red ) = 1/8 = 12.5%
Experimental probability
( ? )/324 = ( ? )%
This experimental probability is ( ? ) than the theoretical probability.
There were ( ? ) winners than expected.
Answer:
The experimental probability is 0.8% more than the theretical probability,
There were approximately 2 more winners than expected
Step-by-step explanation:
Theoretical Probability is given by = 1/8 = 12.5%
Which means that out of 324 players, numbers of winners theoretically are = 0.125 · 324 = 40.5 ≅ 41
To find the probability of experimental data, we have to consider the data recorded by Talia and Yoshi
Recorded winners = 43
Total players = 324
Experimental Probability = Numbers of winners/ Total Number of players · 100
Experimental Probability = 43/321 · 100 = 13.3%
The difference between Experimental and Theoretical Probability is = 13.3% - 12.5% = 0.8%
Difference of Winners ≅ 43 - 40.5 ≅ 2

Step 2: Figure out percentages of what he donated
144(0.25) = 36 models he donated (he made)
216(0.5) = 108 models he donated (he bought)

A triangle has vertices A (-5, -4), B (2, 6), and C (4, -3). The center of dilation is the origin and (x, y) changes to (3x, 3y). What are the vertices of the dilated image?
Answer:
(-15,12),(6,18)(12,-9)
Step-by-step explanation:
Given
A (-5, -4), B (2, 6), and C (4, -3)
Dilated from (x,y) to (3x,3y)
Required
Vertices of the dilated image
First, the scale factor has to be calculated
This is calculated as thus;
Dilation = Original * Scale Factor;
In case of (x,y) to (3x,3y)
So, we have
[tex](3x,3y) = Scale\ Factor * (x,y)[/tex]
Simplify brackets
[tex]3(x,y) = Scale\ Factor * (x,y)[/tex]
Divide both sides by (x,y)
[tex]\frac{3(x,y)}{(x,y)} = \frac{Scale\ Factor * (x,y)}{(x,y)}[/tex]
[tex]\frac{Scale\ Factor * (x,y)}{(x,y)}=\frac{3(x,y)}{(x,y)}[/tex]
[tex]Scale\ Factor =\frac{3(x,y)}{(x,y)}[/tex]
[tex]Scale\ Factor =3[/tex]
Now, the vertices of the new image can be calculated;
Using the formula: Dilation = Original * Scale Factor;
At vertex A(-5,4)
Dilation = (-5,4) * 3
Dilation = (-5*3 ,4*3)
Dilation = (-15,12)
At vertex B(2,6)
Dilation = (2,6) * 3
Dilation = (2*3 ,6*3)
Dilation = (6,18)
At vertex C(4,-3)
Dilation = (4,-3) * 3
Dilation = (4*3 ,-3*3)
Dilation = (12,-9)
Hence, the vertices of the dilated image are (-15,12),(6,18)(12,-9)
Which is the inverse of the function f(x) = 4x − 9?
y = 4(x + 9)
Answer:
The inverse is 1/4x + 9/4
Step-by-step explanation:
f(x) = 4x − 9
y = 4x -9
Exchange x and y
x = 4y -9
Solve for y
Add x to each side
x+9 = 4y
Divide by 4
1/4x + 9/4 = y
The inverse is 1/4x + 9/4

work out the following, giving your answers in their simplest form: 4 2/5 ÷ 1 1/5
Answer:
First make mixed
4 x 5 = 20

1 x 5 = 5
5 + 1 = 6
6/5= 1 1/5
Multiply the reciprocal. The reciprocal is the fraction flipped over like 1/2 becomes 2/1

I WILL MAKE WHOEVER ANSWERS THIS CORRECTLY THE BRAINLIEST :D Rei is barricading a door to stop a horde of zombies. She stacks boxes of books on a table in front of the door. Each box weighs 30 kilograms, and the table with 8 boxes on top weighs a total of 310 kilograms. The total weight W of the barricade in kilograms is a function of x, the number of boxes Rei stacks on the table. Write the function's formula.
Answer:
[tex]W(x)=30x+70[/tex]
Step-by-step explanation:
First, we will find the weight of the table. We know that 8 boxes weighs a total of 240 kg since each box weights 30 kg. Then to find the weight of the table, we can subtract the total weight from the weight of the boxes. Thus:
[tex]W_{\text{table}}=310-240=70\text{ kg}[/tex]
So, the weight of the table is 70 kg.
Now, we can write our function. Let [tex]x[/tex] equal the amount of boxes.
The table is a set weight, so that would be our constant.
Thus, we will have:
[tex]W(x)=30x+70[/tex]
Where W(x) represents the weight of the table after adding x boxes.
30x represents the weight each box of book adds to the total. One box equals 30 kg, two boxes equal 60 kg, etc.
The 70 represents the unchanging weight of the table.
Answer:
Step-by-step explanation:
Well first, we need to find the weight of the table. We know that 8 boxes weighs a total of 240kg (since each box weights 30kg). Thus, we can conclude that the table weighs 70kg by doing 310-240=70.Now, we can write our function. Let equal the amount of boxes.
The table is a set weight, so that would be our constant so, we will have: 30x represents the weight each box of book adds to the total. One box equals 30kg, 2 boxes equal 60kg, etc.The 70 represents the unchanging weight of the table.In terms of W(x), it will be:

This looks like a cosine function. Cosine can take on any x value and still be defined. That means all real numbers will work. When asked for domain, it really just means what x values are defined for this function. We just said, cosine can take any x value
If you didnt know this was a cosine function, you could just visually see the function goes on to -∞ and +∞. There's no reason for the function to run into a critical point

Answer
Part a:This part is already solved in the question:
Part b:The graph is shown at the bottom
Part c:The given equation is:
6 - 2x = 3
-2x = 3-6
-2x = -3
2x = 3
x = 3/2
x = 1.5
This can also be solve by seeing the graph. The equation which was given to us was y = 6 - 2x, and in this part we have to find the value of 3 = 6 -2x , which means y=3.
We can see in the graph that y = 4 when x = 1 and y = 2 when x = 2, so as y=3 is the midpoint of 4 and 2, the values corresponding to y = 3 should be midpoint of 1 and 2 i.e 1.5

Can anyone help me find the inflection point and how to solve this cubic function?
Answer:
x-intercept → (-4, 0)
y-intercept → (0, -2.44)
Domain: (-∞, ∞)
Range: (-∞, ∞)
Step-by-step explanation:
Given function is f(x) = [tex]-\sqrt[3]{(x+3)}-1[/tex]
For x-intercept,
[tex]-\sqrt[3]{(x+3)}-1=0[/tex]
[tex]-\sqrt[3]{(x+3)}=1[/tex]
[tex]\sqrt[3]{(x+3)}=-1[/tex]
(x + 3) = -1
x = -4
Therefore, x-intercept → (-4, 0)
For y-intercept,
Substitute x = 0 in the function.
f(x) = [tex]-\sqrt[3]{(0+3)}-1[/tex]
= [tex]-\sqrt[3]{3}-1[/tex]
= -1.44 - 1
= -2.44
Therefore, y-intercept → (0, -2.44)
Domain: This function is defined for all real values of x.
Therefore, Domain: (-∞, ∞)
Range: Since this function is defined for all real values of x, we will get a distinct output value for every distinct input values.
Therefore, Range: (-∞, ∞)

Answer:
y= 2/3x + 2
Step-by-step explanation:
Answer:
y = 2/3x − 2.
Step-by-step explanation:
We essentially just want a y on the left side, so let's subtract 2x from both sides to get −3y = −2x + 6.
Lastly, let's divide both sides by −3 to get y = 2/3x − 2.
Our equation is now in slope-intercept form, where the slope is 2/3 and our y-intercept is −2.
