Step-by-step explanation:
The systems of linear equations can have:
1. No solution: When the lines have the same slope but different y-intercept. This means that the lines are parallel and never intersect, therefore, the system of equations has no solution.
2. One solution: When the lines have different slopes and intersect at one point in the plane. The point of intersection will be the solution of the system
3. Infinitely many solutions: When the lines have the same slope and the y-intercepts are equal. This means that the equations represents the same line and there are infinite number of solution.
Therefore, based on the explained above, the conclusion is: Systems of equations with different slopes and different y-intercepts never have more than one solution.
suppose the range of a function f is [−2, 9]. what is the range of |f(x)|? (enter your answer using interval notation.)
The range of |f(x)| is [0, 9].
We are given that the range of the function f is [−2, 9]. We are required to find the range of |f(x)|.
Range of a function is defined as the set of all output values (y-values) that a function can produce. It is also called the codomain of the function.
The absolute value of a number is always positive or zero. Therefore, if the function has any negative values in the range, the absolute value of those negative values will be positive and their range will be the same as the positive range.
Therefore, the range of |f(x)| will be [0, 9]. This means that the range of |f(x)| is [0, 9] and is expressed in the interval notation as follows: [0,9].
Therefore, the range of |f(x)| is [0, 9].

What is the vertex of f(x)=x^2−12x+25 ?
Answer:
vertex is (6, -11)
Step-by-step explanation:
Given equation
f(x) = x² - 12x + 25
is that of an upward-facing parabola(since the coefficient of x² is positive).
The vertex will be at a minimum and its x-coordinate can be found by finding the first derivative of f(x), setting it equal to zero and solving for x
f'(x) = d/dx(x² - 12x + 25)
= 2x - 12
f'(x) = 0 ==> 2x - 12 = 0
2x = 12
x = 6
Substitute x = 6 in f(x) to get
f(6) = 6² - 12(6) + 25
= 36 - 72 + 25
= -11
So the vertex is at (6, -11)
Explain the choice of method
The choice of method to the solution of the \pair of equations is substitution method.
What is substitution method?In a pair of equations, we can use substitution method or any other method to solve the equations.
The given pair of equations is
y=-x+5 and
y=-x+3
The first thing is to write the two equations where the constant stays at the right hand side and the two variables stay at the left hand side tyo give
y+x = 5 and
y+x=3
Then we use substitution method to solve for x and y
In this case, make x the subject of the relation in equation 1
x=5-y
Then substitute x=5-y in equation 2
That is 2y = 5
then y = 2.2
Sibstitute y=2.2 in equation to get x=5-2.2
Therefore the value of x=2.8

A rectangular storage container without a lid is to have a volume of 10 m3. the length of its base is twice the width. material for the base costs $15 per square meter. material for the sides costs $9 per square meter. let w denote the width of the base. Find a function in the variable w giving the cost C in dollars) of constructing the box.
The function in variable w giving the cost C (in dollars) of constructing the box is C(w) = 30w² + 270/w. The result is obtained by using the formula of volume and area of the box.
How to determine the function?We have a rectangular storage container without a lid.
Volume, V = 10 m³Length, l = 2wWidth, w = wBase costs $15/m²Sides costs $9/m²The formula of volume of the box is
V = l × w × h
Where
l = lengthw = widthh = heightSo, the height is
10 = 2w × w × h
10 = 2w² × h
h = 10/2w²
h = 5/w²
To find the total cost, calculate the area of base and sides of the box!
See the picture in the attachment!
The base area is
A₁ = 2w × w = 2w² m²
The sides area is
A₂ = 2(2wh + wh)
A₂ = 2(3wh)
A₂ = 6wh
A₂ = 6w(5/w²)
A₂ = 30/w m²
The total cost is
C = $15(2w²) + $9(30/w)
C = $30w² + $270/w
The function of the total cost is
C(w) = 30w² + 270/w
Hence, the function of constructing the box is C(w) = 30w² + 270/w.

Why is 587 divided by 187 0, but on the calculator it is 0. 357?
So the reason for the discrepancy between the calculated result and the result obtained by hand is due to how the remainder is being handled.
By hand, the remainder is kept as a separate value, whereas a calculator may display the result as a decimal instead of showing the remainder.
When dividing 587 by 187 by hand, the result would indeed be 0 with a remainder of 16:
3 | 5 8 7
- 5 6 1
-------
2 7 6
2 8 1
-----
9 6
Therefore, the quotient is 0 with a remainder of 16, which can also be written as 0.085 by dividing the remainder (16) by the divisor (187).
However, when using a calculator, it may display the result as a decimal instead of showing the remainder. In this case, the calculator would compute 587 divided by 187 as 3.136, which can be rounded to 0.357 if the result is being displayed to three decimal places.

The equilibrium constant \((K_{eq})\) relates the concentrations of reactants and products in a chemical reaction at equilibrium. In the given reaction,
\(A + B \rightleftharpoons AB, the\ K_{eq}\ is\ 7\).
When considering the reaction \(2AB \rightleftharpoons 2A + 2B\), the stoichiometric coefficients are doubled on both sides. According to the principles of equilibrium, the equilibrium constant for the modified reaction can be obtained by squaring the original \(K_{eq}\).
Therefore, the \(K_{eq}\) for \(2AB \rightleftharpoons 2A + 2B is (K_{eq})^2 = (7)^2 = 49\). This indicates that the equilibrium position favors the formation of products in the double reaction compared to the original reaction.

find the surface area of the sphere with a diameter of 42 mm (use 3.14 for pi)
The surface area of the sphere is 5538.96 mm²
Given that a sphere has a dimeter of 42 mm, we need to find the surface area of the sphere,
You can use the following formula to determine a sphere's surface area:
Area of Surface = 4πr²
We can find the radius (r) by dividing the diameter by 2:
r = diameter / 2
r = 42 mm / 2
r = 21 mm
Now, we may change the radius value in the calculation to determine the surface area:
Area of Surface = 4π(21 mm)²
Surface Area = 4 × 3.14159 × (21 mm)²
Surface Area ≈ 4 × 3.14159 × 441 mm²
Surface Area ≈ 5,538.60394 mm²
Hence the surface area of the sphere is 5538.96 mm²

Calculate (4 + 10i)^2
By applying the the FOIL method, which stands for First, Outer, Inner, Last we obtained the result -84 + 80i for (4 + 10i)^2.
To calculate (4 + 10i)^2, we can:
First, we multiply the first terms of each binomial:
(4 + 10i) * (4 + 10i) = 16 + 40i
Next, we multiply the outer terms of each binomial:
(4 + 10i) * (4 + 10i) = 16 + 40i
Then, we multiply the inner terms of each binomial:
(4 + 10i) * (4 + 10i) = 16 + 40i
Finally, we multiply the last terms of each binomial:
(4 + 10i) * (4 + 10i) = 100i^2
We know that i^2 is equal to -1, so we can substitute that in:
100(-1) = -100
Putting it all together, we get:
(4 + 10i)^2 = 16 + 40i + 40i + (-100)
= -84+80i
Therefore, by applying this method for squaring a complex number, we obtained the result -84 + 80i for (4 + 10i)^2.

Data mining methods grew out of three fields: statistics, machine learning, and artificial intelligence. We partition data into training and validation data sets randomly to ensure that the resulting models are unbiased and generalize well to new data.
If we were to partition the data in some other manner, we may introduce bias into the model and not have a true representation of its performance.
The essential steps for building a data mining model in the correct order are:
1. Data preparation: Collect and prepare the data for analysis, including cleaning, transforming, and selecting relevant variables.
2. Model selection: Choose the appropriate data mining technique and model to analyze the data.
3. Model building: Develop the model using the selected technique and algorithm.
4. Model evaluation: Test the model's performance on a validation data set and refine as necessary.
