To solve for X we need to have just X on one side. We can do this by dividing each side by 9. Which is equal to the original because we are dividing by the same thing on both sides.
9x/9=18/9
This simplifies to x=2
We can check by putting 2 back into the equation:

true or false: residuals measure the vertical distance between two observations of the response variable.
Residuals measure the vertical distance between two observations of the response variable - False.
An individual data point's residual is a measurement of how well a line fits it. Take a look at this straightforward data set with a line of fit through it.
The discrepancy between expected values of y (the dependent variable) and actual values of y is the residual for each observation. Relative to projected and actual y values, residual is equal to yi. Actual y value minus expected y value equals residual; therefore, r I = y I y i.

Prompt: We recently completed a unit in math about transformations.
Compare and contrast the three types of transformations: translations, reflections, and rotations.
Include the algebraic rules, whether each transformation preserves congruence and any examples of
real-world application.
The translations, reflections, and rotations are types of transformations that change an original object to form a new image, each with its own specific rule and properties. They are used in a variety of real-world applications to change the position or orientation of objects.
There are 3 types of Transformations :
(i) Translation: A translation involves moving an object from one place to another without changing its size or orientation.
The algebraic rule for a translation is to add the same constant to each coordinate of each point
The Translations preserve congruence, meaning that corresponding parts of congruent figures will still be congruent after a translation.
An example of a real-world application of translation is moving a store to a new location.
(ii) Reflection: A reflection involves flipping an object over a line or point, creating a mirror image.
The algebraic rule for a reflection is to negate the value of one of the coordinates.
Reflections preserve orientation, meaning that the orientation of the reflected image is opposite that of the original object.
An example of a real-world application of reflection is looking at your reflection in a mirror.
(iii) Rotation: A rotation involves turning an object about a fixed point, called the center of rotation, through a certain angle.
The algebraic rule for a rotation is to multiply each coordinate by a rotation matrix.
Rotations preserve distance and angle measures, meaning that the lengths of corresponding parts and the angles between them are equal in the original and rotated images.
An example of a real-world application of rotation is turning a steering wheel to change the direction of a car.

CONNECTING CONCEPTS Find the value of x such that the quadrilateral is a parallelogram. Then find the perimeter of the parallelogram. Explain.
The value of 'x' must be 4 units such that the quadrilateral is a parallelogram and the perimeter of the parallelogram is 40 square units.
What is a parallelogram?A basic quadrilateral with two sets of parallel sides is known as a parallelogram. In a parallelogram, the opposing or confronting sides are of equal length, and the opposing angles are of equal size.
The area of a parallelogram is base multiples by height as two triangles form a parallelogram.
We know the opposite sides of a parallelogram are equal.
Therefore, 3x - 1 = x² - 5 and 2x + 1 = x² - 7.
x² - 5 - 3x - 1 = 0.
x² - 3x - 4 = 0, solving for x we have x = 4.
And,
2x + 1 = x² - 7.
x² - 7 - 2x - 1 = 0.
x² - 2x - 8 = 0, solving for x we have x = 4
(Negative values are inadmissible).
The perimeter of the parallelogram is 2×(the sum of the opposite sides).
= 2(3x - 1 + 2x + 1).
= 2(5x).

a culture of yeast doubles in size every 20 minutes. the size of the culture is now n0. find its size in 12 hours. how do you solve these problems? sugar is put in a large quantity of water and the mixture is stirred. after 2 minutes, 50% of the sugar has dissolved. how much longer will it take until 90% of the sugar has dissolved?
How much longer will it take until 90% of the sugar has dissolved can be obtained by the equation t = -(log(1-0.9))/(log(0.5)) + 2
1. To find the size of a yeast culture after 12 hours, you can use the formula: size = n0 * 2^(t/20), where t is the time in minutes. In this case, t = 12*60 = 720, so the size of the culture after 12 hours would be n0 * 2^(720/20) = n0 * 2^36.
2. To find how long it takes for 90% of the sugar to dissolve, you can use the formula: t = -(log(1-x))/(log(0.5)), where x is the percentage of sugar dissolved and t is the time in minutes. In this case, x = 0.9 and we know that 50% of the sugar has dissolved in 2 minutes, so we can find t by plugging in the values and solving for t: t = -(log(1-0.9))/(log(0.5)) + 2.

Two car leave from the ame location but travel in the oppoite direction. The firt car travel an average of 50 mi/hr and leave 15 min before the econd car, which travel an average of 55 mi/hr. How long will each car travel before they are 200 mi apart?
The first car will travel for 38.2 hours and the second car will travel for 38 hours before they are 200 miles apart.
Let x = time in hours for the first car and y = time in hours for the second car. Since the two cars are traveling in opposite directions, we know that the rate of the cars' combined travel is the difference between their two rates. So, we can create the expression:
50x - 55y = 200
We can also create a second expression using the amount of time that passed between the two cars:
x - y = 0.25
We can solve this system of equations with substitution. Let's substitute the second equation into the first:
50x - 55(x - 0.25) = 200
Simplifying, we have:
5.25x = 200.25
Now, we can isolate x:
x = 200.25/5.25 ≈ 38.2 hours
We can use this value to find y. We know that x - y = 0.25, so we have:
y = x - 0.25 = 38.2 - 0.25 = 38 hours
Therefore, the first car will travel for 38.2 hours and the second car will travel for 38 hours before they are 200 miles apart.

solve using elimination
The solution of the equations using elimination method is x = 2.5, y = 5.25
How to solve equations using elimination method?The elimination method is a method used to solve systems of linear equations. It involves manipulating the equations in such a way that one of the variables is eliminated, resulting in an equation in one variable that can be easily solved.
8x+4y = 49 --- (1)
3x+2y = 21 ----(2)
To eliminate x, multiply (1) by 3 and multiply (2) by 8. Then subtract the result. That is:
3 × (8x+4y = 49) = 24x + 12y = 147
8 ×(3x+2y = 21) = 24x + 16y = 168

2. Dilate rectangle ABCD from point A by a scale factor of 2. Calculate the area of the image.
3. Dilate rectangle ABCD from point A by a scale factor of 3. Calculate the area of the image.
This refers to the ratio between the scale of a given original object and a new object. It is its representation but of a different size (bigger or smaller). For example, if we have a rectangle of sides 2 cm and 4 cm, we can enlarge it by multiplying each side by a number, say 2.
Solving for the area and scale factor we have:
L= 5 units
W = 2 units
The area of the rectangle =L * WA = (5 x 2)
A = 10 square units.
If the rectangle is dilated from point A by a scale factor of 2, the area of the image:A= (Scale factor of L * W)* L * W

How much of the circle is shaded? Write your answer as a fraction in simplest form.
Answer:

Step-by-step explanation:
In these type of problems, I like making all of my denominators the same.
1/8 is good.
1/2 is half. 4/8 is also half. I'll use 4/8 because 1/8 also has the 8
A whole circle is 100%, which is 1/1. It's also 8/8
To find the shaded area, we'll first add 1/8 and 4/8. That equals 5/8. We just have to add nominators/top now because the denominator/bottom is the same
Now we'll subtract 8/8 from 5/8. Again denominator is the same, so we only need to subtract the top

while walking in the country, you count 28 heads and 78 feet in a field of pigs and chickens. how many of each animal are there?
Answer:
There are 11 pigs and 17 chickens.
Step-by-step explanation:
Lets let
p = number of pigs
c = number of chickens
Assuming each animal has only one head, then
p + c = 28
And assuming that pigs have four feet and chickens have two feet:
pig feet = 4p
that is, 4 feet for each pig, and
chicken feet = 2c
right? two feet per chicken.
All the feet are:
4p + 2c = 78
Now we have two equations and two unknowns, so we can solve this "system of equations". You can use substitution or elimination method (or even graphing or matrices) I will run through elimination method.
Multiply p+c=28 times -2.
-2p + -2c = -56
then add the whole equation to the other equation. Do this adding vertically, from top to bottom.
-2p + -2c = -56
4p + 2c = 78
_____________
2p = 22
Divide by 2 to solve
p = 11
There are 11 pigs.
Remember,
p + c = 28
11 + c = 28
subtract 11
c = 17
There are 17 chickens.

Pre-Quiz th Percent - Item 35684 Guided Learning Practice A baseball team played 55 games this year. They won 33 games and lost 22 games. What percent of games did they lose? Po
The percentage of games they lose is 40%.
How do you calculate percentage in different ways?The most basic approach is to divide a number by the total and then multiply by 100. For example, if you have 10 out of a total of 25, you would divide 10 by 25 to get 0.4, and then multiply by 100 to get 40%.
Another way to calculate percentage is to use proportion. This involves setting up a proportion with the given numbers and the percent you want to find on one side and 100 on the other side. For example, if you have 10 out of 25 again and want to find the percent, you would set up the proportion 10/25 = x/100. Solve for x and you get 40%.
Another method is to use a percentage calculator. This is a simple tool that allows you to enter two numbers and it will automatically calculate the percentage for you.
Finally, if you need to calculate the difference between two percentages, you can subtract the smaller percentage from the larger one. For example, if you have 10 out of 25 and 15 out of 30, you would subtract 40% from 50% to get 10%.
All of these methods can help you calculate percentages quickly and easily.
Total number of games team played = 55 games
number of games they won = 33
number of games they lose = 22
The percentage of games they lose = 22/55 x 100 = 40%
