The value of x in reduced fraction form is 3/2.
A fraction is a value written in the form of a quotient which has an upper number called numerator and lower called denominator. It represents a part of a whole.
8|6x−6|=24 (given equation)
|6x-6| = 24/8
|6x-6| = 3
6x = 3+6
6x = 9
x = 9/6 ( To reduce divide both the terms with 3 that is a common factor)
x = 3/2
Therefore, we can conclude that the value of x in reduced fraction is 3/2.

a) We can see that an increase in the number of employees (x) also leads to an increase in the number of products produced monthly, thus we can say that there is a positive correlation between the number of employees in the plant and the number of products produced monthly.
A positive correlation occurs when one variable increases with respect to another variable.
b) The function that best fits.
Let's first Find the rate of change(slope).
Take the points;
(x1, y1) ==> (0, 120)
(x2, y2) ==> (10, 200)
Use the slope formula:
[tex]m=\frac{y2-y1}{x2-x1}[/tex]We have:
[tex]m=\frac{200-120}{10-0}=\frac{80}{10}=8[/tex]Use the form:
y = mx + b
Where m is the slope and b is the y-intercept
We have:
y = 8x + b
Substitue 0 for x and 120 for y, to solve for b.
120 = 8(0) + b
120 = b
Thus, we have the function:
y = 8x + 120
f(x) = 8x + 120
c) The slope, m is = 8
The slope indicates that the avearge rate of change between both variables is 8.
The y-intercept can be said to be the point where the line of the plot crosses the y-axis. This means when the number of employees are is zero, the number of products will be 120.
It can also be called the constant value.

1. AMNO with M(-5,2), NO. 4), and O(4.5): (-6, -2) /1 a. What kind of transformation is this? /3 b. What are the vertices of the image after the transformation?
Answer:
a. Translation
b. M'(-11, 0)
N'(-6, 2)
O'(-2, 3)
Explanation:
<-6, -2> indicates that the triangle MNO will be translated 6 units left and 2 units down, so <-6, -2> is a translation.
On the other hand, to know the new vertices, we need to apply the following rule:
(x, y) ----> (x - 6, y - 2)
So, the vertices of the image after the transformation are:
M(-5, 2) ----> (-5 - 6, 2 - 2) = M'(-11, 0)
N(0, 4) ----> (0 - 6, 4 - 2) = N'(-6, 2)
O(4, 5) ----> (4 -6, 5 - 2) = O'(-2, 3)
Therefore, the answers are:

What is the addition method of equations?A mathematical statement that has an "equal to" symbol between two expressions with equal values is called an equation. As in 3x + 5 = 15, for instance. Equations come in a variety of forms, including linear, quadratic, cubic, and others. Using the Addition Method to Solve Two-Variable Equation Systems The addition method, also known as the elimination method, is a third approach to solving systems of linear equations. In this method, the sum is zero by adding two terms with the same variable but opposite coefficients.So, "5x + 15y = -80" + "0.1x = -4.1 -0.3y" using addition method:
Change 0.1x = -4.1 -0.3y to: 0.1x + 0.3y = -4.1Now, "5x + 15y = -80" + "0.1x = -4.1 -0.3y" (refer to the image attached below for calculation)The resulting equation is: 5.1x + 15.3y = -12.1
Therefore, "5x + 15y = -80" + "0.1x = -4.1 -0.3y" using the addition method given equation "5.1x + 15.3y = -12.1".

According to Descartes’ Rule of Signs, if we let
[tex]f(x)=a_nx^n+a_{n-1}x^{n-1}+\cdot\cdot\cdot+a_1x+a_0[/tex]be a polynomial function with real coefficients:
then,
the number of positive real zeros is either equal to the number of sign changes of f(x) or is less than the number of sign changes by an even integer.
the number of negative real zeros is either equal to the number of sign changes of f(-x) or is less than the number of sign changes by an even integer.
In this case,
[tex]f(x)=-4x^6-3x^5+2x^2-4x+1[/tex]We will now check the number of sign changes of f(x)
There are 3 sign changes.
Therefore, f(x) has 3 or 1 positive real roots
Next we find f(-x),

Many bank accounts never go below zero. But some banks will allow a negative balance, at least for a short time, called an overdraft. It means someone has taken out, or 'drafted', more money than was in the account to begin with. Chloe's account went into overdraft. To get back to a positive balance, she deposited money at steady rate of $30.84 per week. After 3 weeks, she had $44.21 in the account. What was the balance when the account went into overdraft?
When the overdraft occurred, the balance was -48.31.
What happens if a bank account balance falls to zero?Major Takeaways. When your account balance drops below zero, you have an overdraft. If you have overdraft protection, your bank may permit a negative balance on your account or may provide one-time exceptions, but they may charge you for each transaction. Bank clients are required by federal regulations to choose to participate in overdraft protection schemes.
Let x represent the balance at the time the account entered overdraft.
He consistently made deposits totaling $30.84 a week in order to return to a positive balance.
Amount deposited per week = $30.84
Amount deposited 3 weeks = 30.84 × 3 = 92.52
Now amount in account after 3 weeks =x+ 92.52
We are given that After 3 weeks, he had $44.21 in the account.
So,x+92.52=44.21
x=44.21-92.52
x=-48.31
Hence The balance when the account went into overdraft was -48.31

The equation to show the change in temperature between 9 a.m. and noon is given as d = x - y.
What is an equation?An equation contains two mathematical expressions that state that they are equal or equivalent.
We use the equation mark (=) to show that two expressions possess equality.
Air temperature at 9 a.m., y -5.8 degrees Celsius
Air temperature at noon, x = -1.6 degrees Celsius
Change in temperature, d = 4.2 degrees Celsius (-1.6 - -5.8)
The equation to show the change is d = x - y, where d is the change in temperature, x is the final temperature, and y is the initial temperature.
Thus, based on the equation, the temperature increased by 4.2 degrees Celsium from the earlier -5.8 degrees Celsius to result in a final temperature of -1.6 degrees Celsius at noon.

Define angles.An angle is a figure in plane geometry that is created by two rays or lines that have a shared endpoint. The Latin word "angulus," which meaning "corner," is the source of the English term "angle." The shared terminus of two rays is known as the vertex, and the two rays are referred to as sides of an angle.
An acute angle is one that is smaller than 90 degrees. Right Angle: An angle with a 90 degree exactness. More than 90 degrees but less than 180 degrees is referred to as an obtuse angle. A straight angle is one that has a 180 degree angle. An angle that is more than 180 degrees but less than 360 degrees is called a reflex angle.

Two lines are 2linese intersect to form linear pairs with equal measures one angle measures 2x other measure 11y+2. x is 45 and y is 8.
The sum of a linear pair of angles is 180 degrees.
Now, we are given two pieces of information. We will use these to develop equations and then solve the equations simultaneously.
First, we know that the two angles are equal, therefore:
2x = 11y+2-------.> equation 1
Second, we know that the two angles form a linear pair of angles, therefore:
2x +11y+2 = 180 -------.> equation 2
Substitute by equation 1 in equation 2:
2x +2x = 180
4x = 180
x = 45
Substitute with the value of x in equation 1 to get y as follows:
2x = 11y+2
2 (45) -2 = 11y
88 = 11y
y = 8
Therefore:
the first angle = 2x = 2(45) = 90 degrees
the second angle = 11(8)+2 = 90 degrees
The two angles are equal and their sum is 180 .
What are linear pair of angle?Line pairs of angles occur when two lines intersect at a single point. Angles are considered linear if they are adjacent after the intersection of these two lines. The sum of the angles of a linear pair is always 180°. Such angles are also called supplementary angles.
If there is a pair of adjacent angles, the pair is a linear pair if the sum of the two angles (their measures) is 180°. Thus, linear pairs of angles always add up to 180°.
