What is the factor theorem formula?
The Factor Theorem states that if a polynomial P(x) has a factor (x-a), then P(a) = 0. In other words, if x-a is a factor of the polynomial, then the value of the polynomial when x=a is equal to zero.
The factor theorem is a fundamental concept in algebra and polynomial functions. This can be useful for determining the roots of a polynomial equation.
Key points:
The factor theorem only applies to polynomials, not other types of functions.The factor (x-a) must be a factor of the polynomial, not just a term.The value of P(a) will be zero only if x-a is a factor of the polynomial, not if it is just a root.The factor theorem can be used to find the roots of a polynomial equation by setting P(x) = 0 and solving for x.The factor theorem is closely related to the remainder theorem, which states that if P(x) is divided by (x-a), the remainder is P(a).In summary, The Factor Theorem is a fundamental concept in Algebra and Polynomials, it helps us understand the relationship between the roots and the factors of a polynomial equation and how a root of a polynomial is related to the value of the polynomial evaluated at that point.

How do you compare complex numbers with real numbers?
Complex numbers and real numbers cannot be directly compared as they are from different number systems.
Complex numbers have both a real and an imaginary component, whereas real numbers only have a real component. However, you can compare the magnitudes (absolute values) of complex numbers with real numbers.
The magnitude of a complex number is the distance from the origin in the complex plane, represented by the absolute value or modulus of the complex number, which is always a positive real number. By comparing the magnitudes of complex numbers, you can determine which one is larger or smaller.
For example, the magnitude of 3 + 4i is 5, and the magnitude of 2 + 3i is 3.5. Therefore, 3 + 4i has a larger magnitude than 2 + 3i.

How do you find the distance between a point and a line vector in 3D?
Finding the distance between a point and a line vector in 3D is a bit more complicated than in 2D, but it is still doable.
What is vector?Vector is a mathematical object that has both magnitude and direction and can be represented by a line segment. It is used in many areas of mathematics and physics. In physics, vectors are used to describe forces, velocities, and accelerations. In mathematics, vectors can be used to represent points in space, transformations, and even linear equations. Vector calculus is used to analyze the behavior of vector fields, or functions of multiple variables.
The formula for finding the distance is based on the vector equation of a line.
Starting with a line given by vector $\vec{r}= \vec{a}+t\vec{v}$ , where $\vec{a}$ is the point on the line, $\vec{v}$ is a unit vector, and $t$ is a scalar parameter, and a point $\vec{b}$, the distance between the point and the line can be found by first computing the vector $\vec{p}=\vec{a}-\vec{b}$. Then, the distance is given by $d=\frac{|\vec{p}\cdot \vec{v}|}{|\vec{v}|}$.
This formula can also be used to find the closest point on the line to the point $\vec{b}$. The closest point on the line is given by $\vec{a}+t\vec{v}$, where $t=\frac{\vec{p}\cdot \vec{v}}{|\vec{v}|^2}$.
Thus, finding the distance between a point and a line in 3D involves computing the vector $\vec{p}$ and then using the formula above to compute the distance.

What is a vector?A vector is body which has both magnitude and direction. Geometrically, a vector can be imagined as a directed segment whose length corresponds to the absolute value of the vector and whose direction is indicated by an arrow. The direction of the vector is tail to head.
Suppose a 3D line is given by two points and the reference diagram attached below. where x₁ = (x₁,y₁ ,z₁) and x₂ = (x₂,y₂,z₂) are above it, giving us a vector along the line. [tex]v=[x_1+(x_2-x_1)t; y_1+(y_2-y_1)t; z_1+(z_2-z_1)t].[/tex]
The squared distance between a point on the line with parameter t and a point x₀ = (x₀, y₀, z₀) is therefore;
d² = [(x₁ - x₀) + (x₂ - x₁)t²] + [(y₁ - y₀) + (y₂ - y₁)t²] + [(z₁ - z₀) + (z₂ - z₁)t²]
To minimize the distance, set d(d²)/dt = 0 and solve for t to obtain:
t = [tex]\frac{-((x_1-x_0)(x_2-x_1))}{|x_2-x_1|^2}[/tex]

Using vector quadruple product:
(A × B)² = A²B² - (A.B)²
Where x denotes the cross product then gives:
d² = [tex]\frac{|(x_2-x_1)x(x_1-x_0)|^2)}{|x_2-x_1|^2}[/tex]

How do you find the perpendicular bisector of a line segment?
The perpendicular bisector can be found by solving for the equation of the line and substituting the two points.
The perpendicular bisector of a line segment can be found by using the midpoint formula. The midpoint formula is used to find the midpoint of two points (x1,y1) and (x2,y2). The formula is:
Midpoint = (x1 + x2)/2, (y1 + y2)/2
Once the midpoint is found, the slope of the perpendicular line is found by using the negative reciprocal of the original line. The formula for the slope of the perpendicular line is y = -1/m * x + b, where m is the slope of the original line.
The equation of the perpendicular bisector is then found by substituting the slope and the midpoint into the equation of a line, y - y1 = m(x - x1).
Finally, the perpendicular bisector can be found by solving for the equation of the line and substituting the two points. The resulting equation is the equation of the perpendicular bisector.

a. Write a linear model that represents the monthly cost for water as a function of the number of gallons you will used.
b. Find the cost of 2,000 gallons.
Answer:
See below, and note the interpretation of the question.
Step-by-step explanation:
See the attached image for a graph of all the lines and points.
1. Write an equation in slope-intercept form of the line given the slope=" 1/4 pass through (-2,1).
1. Look for an equation of the form y=mx+b, where m is the slope and b is the y-intercept (the value of y when x is zero).
We are given the slope, so use that for m: y = (1/4)x + b.
We need a value of b that forces the line through point (-2,1). This can be done by entering the point into the above equation and solving for b:
y = (1/4)x + b
1 = (1/4)*(-2) + b [for (-2,1)]
1 = -0.5+ b
b = 1.5
The equation is y = (1/4)x + 1.5
2. Write an equation in slope-intercept form of the line that passes through (0,4) and (5,19)
1. Look for an equation of the form y=mx+b
2. Determine the slope by calculating the Rise and Run of the two given points:
Going from (0,4) to (5,19):
Rise = 19-4 = 15
Run = 5 - 0 = 5
Rise/Run, or slope, m = (15/5) or 3
The equation with the slope of 5:
y = 5x+b
3. To find b, enter either of the 2 points into the equation and solve for b:
y = 5x+b
4 = 5*(0)+b for (0,4)
b = 4
The equation is y=5x+4
3. Write a linear function f with the given values.
Are the expressions written correctly? I see f and g. I'll assume the forst two are meant to be f, and the last two a new function, g(x).:
a. f(0) = 2, f(2) = -3
b. g(-4) = -5, g(3) = - 1.
These results supply us with 2 points for each function [line]:
f: (0,2) and (2,-3)
g: (-4,-5) and (3,-1)
We can use these two points to find the slope for lines f and g:
f: (0,2) and (2,-3)
Rise = -3 - 2 = -5
Run = 2 - 0 = 2
Slope = (-5/2) or -2.5
The equation for f is y = (-2.5)x + b
Enter one of the 2 points to find b:
y = (-2.5)x + b
y = (-2.5)*(0) + b for (0,2)
2 = b
The equation for f is f(x) = -2.5x+2
Do the same for g:
(-4,-5) and (3,-1)
Rise = (-1 - (-5)) = 4
Run = (3 - (-4)) = 7
Slope = 4/7 or 0.571

The equation of the line that passes through the point (10, -4) and has the slope -2/5 is y = 2/5 x
How to identify the equation of the lineThe slope, m of the linear function is given as -2/5.
The equation of the line that passes through point (10, -4) is calculated using the point slope formula which is given as:
x₁ = 10
y₁ = -4
m = -2/5
substituting in to the formula
(y - y₁) = m (x - x₁)
y + 4 = -2/5 (x - 10)
y + 4 = -2/5 x + 4
y = 2/5 x + 4 - 4
y = 2/5 x
The equation of the line is given as y = 2/5 x

In how many ways can 345 be written as the sum of an increasing sequence of two or more consecutive positive integers
There are 7 ways for 345 to be written as the sum of an increasing sequence of two or more consecutive positive integers.
We need to find consecutive numbers (an arithmetic sequence that increases by 1) that sum to 345. This calls for the sum of an arithmetic sequence given that the first term is k, the last term is g, and with n elements, which is:
n(k+g)/2.
There are 7 ways can 345 be written as the sum of an increasing sequence of two or more consecutive positive integers.
We look for sequences of n consecutive numbers starting at k and ending at k + n − 1. We can now substitute g with k+n- 1. Now we substitute our new value of g into n(k + g)/2 to get the sum i.e.
n(k+k+n-1)/2 = 345
This simplifies to n(2k+n-1)/2 = 345.
This gives a nice equation. We multiply out the 2 to get that n. (2k+n-1): =690. This leaves us with 2 integers that multiply to 690 which leads us to think of factors of 690.
We know the factors of 690 are:
1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
So, through inspection (checking), we see that only 2, 3, 5, 6, 10, 15, and 23 work. This gives us the answer to 7 ways.

Please help!
I genuinely don't know how to do this, a step-by-step would do great. Thank you.
Answer:
x = 10
Step-by-step explanation:
Because the triangles are similar, the following equations must be solved in order to find out how much bigger or smaller the triangle is.
10 * y = 15
16 * y = 24
You'll find that
y = 1.5
Then, you are able to insert y into the following equation and solve for x
(x - 4) * y = 9
(x - 4) * 1.5 = 9
1.5x - 6 = 9
1.5x = 15
x = 10
We can plug x back into the previous equation in order to check if it is correct
(x - 4) * 1.5 = 9
(10 - 4) * 1.5 = 9
6 * 1.5 = 9
9 = 9
