By cancelative property, the roots of quadratic equation x² + 4 · x - 20 are: Exact: - 2 + 2√6, - 2 - 2√6, Approximate: 2.899, -6.899.
How to find the roots of a polynomial by cancelative property
In this problem we must factorize a quadratic equation and use an algebraic property known as cancelative property, defined as:
If a · b = 0, then a = 0 or b = 0.
In addition, we can apply the following factorization rule:
x² - (r₁ + r₂) · x + r₁ · r₂ = (x - r₁) · (x - r₂)
First, factorize the quadratic equation:
x² - (- 2 + 2√6 - 2 - 2√6) · x + (- 2 + 2√6) · (- 2 - 2√6)
(x + 2 - 2√6) · (x + 2 + 2√6)
Second, apply cancelative property:
x + 2 - 2√6 = 0
x = - 2 + 2√6
x + 2 + 2√6 = 0
x = - 2 - 2√6

Buddy walks 5000 feet due North, then turns and walks 4000 feet due East. If he walked in a straight line from his starting position to his final position, how many miles would he walk?
Answer: 1.2 miles
You can find the answer by using the pythagorean theorem.
a^2 + b^2 = c^2.
(5000)^2 + (4000)^2 = c^2
25 million +16 million = c^2
41 million = c^2
Take the square root of both sides in order to get the value of C.
C = about 6,403 feet.
1 mile = 5280 feet
6403/5280 = 1.2
Buddy would walk about 1.2 miles

Regression equation:
Final Answer:
You can substitute a homework grade of 37 into the equation in place of x, to find the projected test grade.
What is linear regression?Linear regression is a statistical method that is used to study the relationship between two continuous variables, often referred to as the independent variable (x) and the dependent variable (y). The goal of linear regression is to find the best-fitting line that describes the relationship between these two variables. The best-fitting line is known as the regression line, and it is represented by the equation y = mx + b, where m is the slope of the line, and b is the y-intercept.
To find the linear regression equation, we need to use the least squares method to find the line of best fit that describes the relationship between the homework grade (x) and the test grade (y). The equation of the line is in the form of y = mx + b, where m is the slope and b is the y-intercept.
To find the slope (m) and y-intercept (b) we can use the following formulas:
m = (n(Σxy) - (Σx)(Σy)) / (n(Σx²) - (Σx)²)
b = (Σy - m(Σx)) / n
where n is the number of data points, Σx and Σy are the sum of x and y values, Σxy is the sum of the product of x and y values, and Σx² is the sum of the squares of x values.
Given the data points, we can use this information to calculate the slope and y-intercept, and write the linear regression equation.
Given the linear regression equation of the form y = mx + b
You can substitute a homework grade of 37 into the equation in place of x, to find the projected test grade.

note: enter your answer and show all the steps that you use to solve this problem in the space provided. use the circle graph shown below to answer the question. the image is a color pie chart divided into 5 portions, and is titled pets owned by sixth graders.
starting from the 12 o'clock position at the top and going clockwise toward the right is dark blue portion labeled dogs, 45 percent. next portion if 30 sixth graders own birds, how many sixth graders were surveyed?
Total number sixth graders were surveyed is 600.
"percent" is Latin for "out of 100," so 5 % is literally 5 out of 100
Now--if it were 5 kids with birds, you would know that there were 100 total kids. But it's 30 kids, which is way more than 5; so your total number of kids is going to be way more than 100.
So what you need to do here is figure that "30 sixth graders own birds
i.e. 30 is 5% of some number."
How many times bigger than 5 is 30? (6 times, because 5 x 6 = 30, or you can think of it as 30 divided by 6 = 5)
So if you had to do 5 TIMES 6 to get to 30, you have to do 100 TIMES 6 to get the total number sixth graders were surveyed.
What's 100 x 6?
= 600.
So your total number sixth graders were surveyed is 600.

Find the selling price.
Cost to store: $65
Markup: 80%
The selling price for the article if it is equal to marked price will be $117
using profit and loss formulas.
What is profit and loss formula?
Profit and Loss formula is used in mathematics to determine the price of a commodity in the market and understand how profitable a business is. Every product has a cost price and a selling price. Based on the values of these prices, we can calculate the profit gained or the loss incurred for a particular product. The important terms covered under this are cost price, fixed, variable and semi-variable cost, selling price, marked price, list price, margin, etc.
For example, for a shopkeeper, if the value of the selling price is more than the cost price of a commodity, then it is a profit and if the cost price is more than the selling price, it becomes a loss.
Now,
Given Cost price=$65
Marked up price = 180%*$65
As
Marked up price = selling price
Therefore
selling price= 180%*$65

How to calculate the slope of any straight line?In Mathematics and Geometry, the slope of any straight line can be calculated by using this mathematical equation (expression);
Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Slope (m) = (y₂ - y₁)/(x₂ - x₁)
From the information provided above, we have the following data points located on the line:
Points on the x-coordinate = (-3/2, 3/2).
Points on the y-coordinate = (-3/2, 3/2).
Substituting the given data points into the slope formula, we have the following;
Slope (m) = (y₂ - y₁)/(x₂ - x₁)
Slope (m) = (3/2 + 3/2)/(3/2 + 3/2)
Slope (m) = 3/3 = 1
At point (-3/2, -3/2), an equation of this line can be calculated by using the point-slope form as follows:
y - y₁ = m(x - x₁)
Where:
m represents the slope.x and y are the data points.c represents the intercept.y - (-3/2) = 1(x - (-3/2))
y + 1.5 = x + 1.5

Answer:
¿Qué quieres comer?
Step-by-step explanation:

Answer:
The machine makes 45 bottles per minute.
Step-by-step explanation:
We can first find the slope through this equation: [tex]\frac{y2-y1}{x2-x1}[/tex]
Since we are given two points, (2,90) and (7,315), we can plug those two points into the formula given above:
[tex]\frac{315-90}{7-2}[/tex]
= 45
Therefore, m = 45.
Now, we can pick one of the two points given--in this case, I'll use (2,90)--to find the equation of the line: [tex]y-y1 = m(x-x1)[/tex]
For (2,90), y1 will be 90, and x1 will be 2. Let's also plug in m:
y - (90) = 45(x - 2)
We can solve for y now to find what y=mx+b is:
y = 45(x-2) + 90
y = 45x
Since the problem asks how many bottles the machine can make per minute, we can plug x = 1: 45(1) = 45
The machine makes 45 bottles per minute.

Please find attached the image of the enlargement of the shape X by a scale factor of -1 created using MS Word, which is a drawing equivalent to option B. The correct option is therefore;
B.
What is an enlargement transformation?An enlargement transformation is one in which the pri-image object size is scaled about a center of enlargement, using a scale factor, with the sign of the scale factor indicating the direction of the enlargement, which for a +ve sign is on the same side, and for a -ve sign is on the other side of the center of enlargement.
An enlargement by a scale factor of -1, can be obtained by producing the image on the alternate side of the center of enlargement, which with a scale factor of -1, is the same size as the size of the image.
Therefore, the dilation by a scale factor of -1, with the center at the origin, produces an image which is equivalent to a reflection of the original object (pre-image), across the y-axis followed by a reflection across the y-axis.
The image of the object following the dilation will therefore be the mirror image of the mirror image of the object reflected across the y-axis, which takes the shape of a vertically flipped, left flipped F, which is option B

What is the equation of the line that passes through the point (-3,-8) and has a slope of 0
Answer:
The equation of a line in the form of y = mx + b, where m is the slope, x is the variable and b is the y-intercept.
Given a point and the slope, we can find the equation of the line that passes through that point. We know that the slope of the line is 0, so we can write the equation of the line as:
y = 0x + b
We also know that the line passes through the point (-3,-8), so we can substitute these values into the equation and solve for b, the y-intercept:
-8 = 0(-3) + b
-8 = 0 + b
b = -8
So the equation of the line that passes through the point (-3,-8) and has a slope of 0 is:
y = 0x - 8
This line is a horizontal line with y-intercept -8, which means that the line passes through the point (0,-8)
