The triangle after the reflection over the line y = x has image points: (x'k), (5,-2), and (-6,-1). The corresponding preimage points are: (3,4), (4,3), and (-2,5).

The given information describes a triangle undergoing a transformation with a reflection over the line y = x. Let's analyze the preimage and image points to determine the transformation.

Preimage points: (3,4), (4,3), and (-2,5)

Image points: (x'k), (5,-2), and (-6,-1)

Since we know the reflection is over the line y = x, we can determine the image points by swapping the x and y coordinates of the preimage points. Therefore, the reflection can be represented by the transformation: (x, y) -> (y, x).

Applying this transformation to the preimage points, we get the image points as follows:

(3,4) -> (4,3)

(4,3) -> (3,4)

(-2,5) -> (5,-2)

Now we can check if the image points match the given image points:

(4,3) matches (x'k)

(3,4) matches (5,-2)

(5,-2) matches (-6,-1)

#5 - [tex]x=-2[/tex]

#6 - [tex]x=-4[/tex]

#7 - [tex]x=2[/tex]

#8 - [tex]x=10[/tex]

Step-by-step explanation:

Solve the following multi-step equations.

#5 - [tex]-10-7x=-3x-2[/tex]

#6 - [tex]-13-4x=x+7[/tex]

#7 - [tex]x-2=10-5x[/tex]

#8 - [tex]3x-1=4x-11[/tex]

[tex]\hrulefill[/tex]

I will use the SCAM method to solve these multi-step equations.

[tex]\mathbb{S}\text{implify each side of the equation} \\\\\\\mathbb{C}\text{ombine like terms, collect variables on one side }\\\\\\\mathbb{A}\text{dd and/or subtract}\\\\\\\mathbb{M}\text{ultiply and/or divide}[/tex]

What is our goal when solving equations?

Our goal is to isolate the variable.

Remember when solving equations, whatever you do to one side of the equation you must do to the other.  [tex]\hrulefill[/tex]

Now solving #5,

[tex]-10-7x=-3x-2[/tex]

Observing the equation, we notice on either side of the equation we cannot simplify using the distributive property or order of operations ("PEMDAS"). Well will skip to the "C" in SCAM.

Add "7x" to each side of the equation.

[tex]\Longrightarrow -10-7x+7x=-3x-2+7x\\\\\\\Longrightarrow -10=4x-2[/tex]

The variable "x" now appears on one side of the equation. Now we are on the "A" in SCAM.

Add the value of "2" to each side of the equation.

[tex]\Longrightarrow -10+2=4x-2+2\\\\\\\Longrightarrow -8=4x[/tex]

Now on the "M" in SCAM.

Divide both sides of the equation by the value of "4."

[tex]\Longrightarrow \dfrac{-8}{4}=\dfrac{4}{4}x\\\\\\\Longrightarrow -2=x\\\\\\\therefore \boxed{x=-2}[/tex]

Thus, problem #5 is solved.

[tex]\hrulefill[/tex]

For the rest of the problems I will simply show the operations I am doing.

Now solving #6,

[tex]-13-4x=x+7\\\\\\\Longrightarrow -13-4x+4x=x+7+4x\\\\\\\Longrightarrow -13=5x+7\\\\\\\Longrightarrow -13-7=5x+7-7\\\\\\\Longrightarrow -20=5x\\\\\\\Longrightarrow \dfrac{-20}{5}= \dfrac{5}{5}x\\\\\\\Longrightarrow-4=x\\\\\\\therefore \boxed{x=-4}[/tex]

Thus, problem #6 is solved.

[tex]\hrulefill[/tex]

Now solving #7,

[tex]x-2=10-5x\\\\\\\Longrightarrow x-2+5x=10-5x+5x\\\\\\\Longrightarrow 6x-2=10\\\\\\\Longrightarrow 6x-2+2=10+2\\\\\\\Longrightarrow 6x=12\\\\\\\Longrightarrow \dfrac{6}{6}x=\dfrac{12}{6}\\\\\\\therefore \boxed{x=2}[/tex]

Thus, problem #7 is solved.

[tex]\hrulefill[/tex]

Now solving #8,

[tex]3x-1=4x-11\\\\\\\Longrightarrow 3x-1-3x=4x-11-3x\\\\\\\Longrightarrow -1=x-11\\\\\\\Longrightarrow -1+11=x-11+11\\\\\\\Longrightarrow 10=x\\\\\\\therefore \boxed{x=10}[/tex]

The variable x as the subject​ of the equation is x = n(w - 2)

From the question, we have the following parameters that can be used in our computation:

x/n + 2 = w

Subtract 2 frm both sides of the equation

So, we have

x/n = w - 2

Next, we have

x = n(w - 2)

Hence, the solution is x = n(w - 2)

Answer:

Your correct

Step-by-step explanation:

The transversal,a, creates right angles for line b, c, and d. This they are parallel

The simplified form of the expression (-3x² + x + 5) - (4x² - 2x) is -7x² + 3x + 5.

To simplify the expression (-3x² + x + 5) - (4x² - 2x)

you will have to perform the subtraction of the two polynomials.

This can be done by first removing the brackets by applying the negative sign of the second polynomial.

After removing the brackets, you can combine like terms.

Hence;

(-3x² + x + 5) - (4x² - 2x)

= -3x²+ x + 5 - 4x²+ 2x (applying negative sign)

= -3x² - 4x² + x + 2x + 5 (combining like terms)

= -7x² + 3x + 5

The point is (3, 2 1/3).

Given the equation of the line,y + 3 = 1/3(x + 3)

To identify a point the line passes through and the slope of the line, we first need to convert the equation of the line into slope-intercept form.y + 3 = 1/3(x + 3) y = 1/3x + 1

As we can see from the slope-intercept form of the equation, the slope of the line is 1/3.

To graph the line, we need to choose two points on the line and connect them with a straight line.

Let's choose the y-intercept and another point on the line.

The y-intercept is (0,1). To find another point, we can choose x = 3.y = 1/3x + 1y = 1/3(3) + 1y = 2(1/3)

Thus, the point is (3, 2 1/3).

The factors of the original expression, u and v to produce a sum of simpler terms, the derivative of y with respect to x is: y' = -2x⁴ - x² - 10x + 15

Given the expression y = (3 - x²) (x³ - 5x + 5),

We need to find the derivative of y with respect to x.

We can find y' using two methods:

Method 1: Applying the Product RuleIf y = uv, then we know that y' = u'v + uv'Applying this formula to the given expression, We get:

y = (3 - x²) (x³ - 5x + 5)u = (3 - x²) and v = (x³ - 5x + 5)

Differentiating u and v, we get:u' = -2x and v' = 3x² - 5

Substituting these values into the formula for y', we get:

y' = u'v + uv' = (-2x) (x³ - 5x + 5) + (3 - x²) (3x² - 5)

Simplifying this expression, we get:

y' = -2x⁴ + 10x² - 10x - 3x² + 15 = -2x⁴ - x² - 10x + 15

Method 2: Multiplying the Factors to Produce a Sum of Simpler Terms to Differentiate

Expanding the given expression, we get:

y = 3x³ - 15x + 15 - x⁵ + 5x³ - 5x - 3x² + 15x² - 15x

Differentiating this expression, we get: y' = 9x² - 15 + 0 - 5x⁴ + 15x² - 5 - 6x + 30x - 15

Simplifying this expression, we get:

y' = -2x⁴ - x² - 10x + 15

Therefore, the derivative of y with respect to x is:y' = -2x⁴ - x² - 10x + 15

The correct answer is that Alan mixed up the positions of 8 and 25 in the equation (8)(x) = (25)(200). This mistake led to incorrect calculations and the wrong answer.

Alan's error lies in mixing up the positions of 8 and 25 in the equation (8)(x) = (25)(200). In the original proportion, the correct equation is (x/200) = (8/25).

However, Alan mistakenly wrote it as (8)(x) = (25)(200), reversing the positions of 8 and 25. This error leads to incorrect calculations and ultimately an incorrect answer of x = 625.

Let's break down Alan's steps to understand his mistake:

StartFraction x over 200 EndFraction = StartFraction 8 over 25 EndFraction.

Alan correctly writes down the proportion.

(8)(x) = (25)(200).

Here is where Alan's error occurs. Instead of multiplying 8 by x and 25 by 200, he mistakenly swaps their positions. This mistake results in incorrect products.

8x = 5,000.

Alan multiplies incorrectly and obtains 5,000 as the product of 25 and 200.

StartFraction 8x over 8 EndFraction = StartFraction 5,000 over 8 EndFraction.

Alan divides both sides of the equation by 8, which is the correct step.

x = 625.

Alan divides 5,000 by 8 to find the value of x, which is his final incorrect answer. So, the correct option is he mixed up the positions of 8 and 25 in the equation (8) (x) = (25) (200).

The correct Option is C. Dominic buys about 18 ounces of romaine lettuce in the 64-ounce container of salad mix.

From the pie chart, we can infer that the percentage of romaine lettuce in the salad mix is 27%.

We can find the number of ounces of romaine lettuce in a 64-ounce container of salad mix by multiplying 64 by 27/100.

This is because we want to find what fraction of the whole salad mix is romaine lettuce, and then multiply it by the total number of ounces in the container.

Using proportions, we can find that:Let x be the number of ounces of romaine lettuce in a 64-ounce container of salad mix.

27/100 = x/64

Solving for x, we get:x = (27/100) * 64 = 18.28

Therefore, there are about 18.28 ounces of romaine lettuce in a 64-ounce container of salad mix.

However, since we are asked to give an approximate answer, we can round this to the nearest whole number, which is 18.

So, Dominic buys about 18 ounces of romaine lettuce in the 64-ounce container of salad mix.

The probability that a data value in a normal distribution is between a z-score of 1.65 and a z-score of 2.24 is approximately 6.9%.

To calculate the probability, we need to use the standard normal distribution table or a statistical calculator.

Look up the cumulative probability for the lower z-score (1.65):

From the standard normal distribution table or a statistical calculator, we find that the cumulative probability for a z-score of 1.65 is approximately 0.9505.

Look up the cumulative probability for the higher z-score (2.24):

Similarly, the cumulative probability for a z-score of 2.24 is approximately 0.9875.

Calculate the probability between the two z-scores:

To find the probability between the two z-scores, we subtract the cumulative probability of the lower z-score from the cumulative probability of the higher z-score.

Probability = Cumulative probability (Higher z-score) - Cumulative probability (Lower z-score)

Probability = 0.9875 - 0.9505

Probability = 0.037

Convert the probability to a percentage:

Multiply the probability by 100 to express it as a percentage.

Probability (in percentage) = 0.037 × 100

Probability (in percentage) = 3.7%

Rounded to the nearest tenth of a percent, the probability that a data value in a normal distribution is between a z-score of 1.65 and a z-score of 2.24 is approximately 6.9%.

This method of approximation is derived from the mathematical concept of limits and the definition of the number e as the limit of (1 + 1/n)^n as n approaches infinity. By increasing the value of n, we approach closer and closer to the actual value of e.

To approximate the mathematical constant "e," you can use the expression (1 + 1/n)^n, where n is a large value. As n approaches infinity, this expression converges to the value of e. The larger the value of n, the closer the approximation will be to the actual value of e.

For example, let's substitute a large value, say n = 10,000, into the expression:

Approximation of e ≈ (1 + 1/10,000)^10,000

Calculating this expression, we get an approximation of e as approximately 2.7181459. Although it's not an exact value, it is a close approximation of the mathematical constant.

To use this approximation, choose a large value for "n", such as 10,000 or 100,000, and evaluate the expression (1 + 1/n)^n using a calculator or computer program. The result will be a close approximation of the value of "e". The larger the value of "n", the more accurate the approximation will be.
