Basically, when simplifying an expression, try to make it as simple as possible. After all, don't add, subtract, multiply, or divide anything. For example, consider the following equation: 4 + 6 + 5.

For example, 1/2 (x + 4) can be simplified as x / 2 + 2. Let's look at another example to understand. Example: Simplify the formula: 3/4x + y / 2 (4x + 7). Using the law of distribution, a given equation can be written as 3/4x + y / 2 (4x) + y / 2 (7).

The scale factor of the dilation is 2/3. This means that the image point is two-thirds the distance from the original point to the center of dilation.

To find the scale factor of the dilation, we can use the formula:

[tex]\[ \text{scale factor} = \frac{\text{image point}}{\text{original point}} \][/tex]

Given that the image of (6, 9) under the dilation is (4, 6), we can substitute these values into the formula:

[tex]\[ \text{scale factor} = \frac{(4, 6)}{(6, 9)} \]\[ \text{scale factor} = \left( \frac{4}{6}, \frac{6}{9} \right) \][/tex]

Simplifying the fractions:

[tex]\[ \text{scale factor} = \left( \frac{2}{3}, \frac{2}{3} \right) \][/tex]

B. The scale factor is 2/3

To determine the scale factor of the dilation, we need to compare the coordinates of the original point 6, 9 and its image 4 , 6

The formula for dilation of a point x, y by a scale factor k is:

[tex]\[(x', y') = (kx, ky)\][/tex]

Given:

- Original point 6 , 9

- Image point 4 , 6

We need to find the scale factor k such that:

[tex]\[4 = k * 6 \quad \text{and} \quad 6 = k * 9\][/tex]

Let's solve these equations.

1. 4 = 6k

[tex]\[k = \frac{4}{6} = \frac{2}{3}\][/tex]

2. 6 = 9k

[tex]\[k = \frac{6}{9} = \frac{2}{3}\][/tex]

Both equations give the same scale factor of 2/3.

Answer: x = 9 -3y

Step-by-step explanation:

Hi, to answer this question we have to solve the system by substitution:

a)3x − 4y = 12

b)2x + 6y = 18

If we isolate "y" on b)

2x + 6y = 18

2x = 18 -6y

x = 18/2 - 6/2y

x = 9 -3y is a possible equation

Doing the same thing with the other equation a) , and isolating "y" in both expressions, the only possible equation is the one founded above.

Answer:

3-2 notebooks= 11$-8$=3 $

so 2 notebooks= 2*3=6 $

so a pack of pens is 8$-6$=2$

Step-by-step explanation:

The cost of a pack of pens is $2 and it can be determined by using a system of equations.

Given that,

Daniel brought 2 notebooks and a pack of pens for $8.

Jose bought 3 notebooks and a pack of pens for $11.

We have to determine,

What is the cost of a pack of pens?

According to the question,

Let, the cost of notebook be x,

And the cost of a pack of pens is y.

Daniel brought 2 notebooks and a pack of pens for $8.

2x + y = 8

Jose bought 3 notebooks and a pack of pens for $11.

3x + y = 11

On subtracting both the equation

2x + y - (3x + y ) = 8-11

2x + y -3x -y = -3

-x = -3

x = 3

Substitute the value of x in the equation 1,

2x + y = 8

2(3) + y = 8

6 + y = 8

y = 8-6

y = 2

Hence, The cost of the notebook is $3 and the cost of a pack of pens is $2.

Answer:

[tex]g^{-1}[/tex](x) = [tex]\frac{5x+45}{3}[/tex]

Step-by-step explanation:

let y = g(x) and rearrange making x the subject

y = [tex]\frac{3}{5}[/tex] x - 9 ( add 9 to both sides )

y + 9 = [tex]\frac{3}{5}[/tex] x

Multiply both sides by 5 to clear the fraction

5y + 45 = 3x ( divide both sides by 3 )

[tex]\frac{5y+45}{3}[/tex] = x

Change y back into terms of x, thus

[tex]g^{-1}[/tex](x) = [tex]\frac{5x+45}{3}[/tex]

The inverse is g⁻¹(x) = (5/3)*(x + 9)

How to find the inverse?

for a function f(x), the inverse f⁻¹(x) is defined as:

if f(x) = y

f⁻¹(y) = x

For this case, we can write:

g(g⁻¹(x)) = x

(3/5)*g⁻¹(x) - 9 = x

(3/5)*g⁻¹(x) = x + 9

g⁻¹(x) = (5/3)*(x + 9)

Answer:

1.5887 cm

Step-by-step explanation:

If the time is 13:30, The hour pointer will be between the numbers 1 and 2.

Each number of the 12 number clock is separated by 30 degrees, so the hour pointer is at 45 degrees.

The minute pointer is at 30 minutes, so it is in number 6, being therefore at angle 180.

The angle formed by the pointers will be 180 - 45 = 135 degrees.

We can draw a triangle with both pointers and this angle (image attached)

So, we can calculate the distance between the tip of the pointers (let's call it "d") using law of cosines:

d^2 = 0.7^2 + 1.2^2 - 0.7*1.2*cos(135)

d^2 = 0.49 + 1.44 - (-0.5940) =  2.524

d = 1.5887 cm

The distance between the tip of the pointers (let's call it "d") using law of cosines is 1.5887 cm.

Step-by-step explanation:

b(4b² - 9) - 3(4b² - 9)

(4b² - 9)(b - 3)

(2b - 3)(2b + 3)(b - 3)

Answer:

[tex](4b^{2}-9)(b-3)[/tex]

Step-by-step explanation:

In order to factor this expression you need to factor by grouping.

First focus on factoring the first two terms them factor the last two terms

1. Lets focus on the first 2 terms:

[tex]4b^{3} -12b^{2}[/tex] (You can factor out [tex]4b^{2}[/tex])

[tex]4b^{2} (b-3)[/tex] (this is what you're left with

2. Lets focus on the last 2 terms:

[tex]-9b+27[/tex] (You can factor our a -9)

[tex]-9(b-3)[/tex] (this is what you're left with

3. Now lets put both of the factored parts together:

[tex]4b^{2} (b-3)-9(b-3)[/tex] (Since both equations have the factor (b-3) in common that is one of our answers) (pull out that factor)

[tex](b-3)[/tex]

Now whatever is left create the second factor:

[tex](4b^{2} -9)[/tex]

So, [tex](4b^{2} -9)(b-3)[/tex] are the factors that make this expression.

You can double check that these are the right factors by using the FOIL method.

If you use the FOIL method it forms the original expression [tex]4b^{3} -12b^{2} -9b+27[/tex]

so we know for sure these are the right factors.

I will upload an image of how to use the FOIL method.

Answer:

$26,500.

Step-by-step explanation:

It is given that Ed is a car salesman. he makes 1.5% commission on each car he sells.

He made $397.50 on the last car he sold.

We need to find the sales price of the car.

Let x be the selling price of the car.

1.5% of x = $397.50

[tex]x\times \dfrac{1.5}{100}=397.50[/tex]

[tex]0.015x=397.50[/tex]

Divide both sides by 0.015.

[tex]x=\dfrac{397.50}{0.015}[/tex]

[tex]x=26,500[/tex]

Therefore, the sales price of the car is $26,500.

The sales price of the car is $26,500.

To find the sales price of the car, we need to divide the commission amount by the commission rate.

First, let's convert the commission rate to a decimal. 1.5% is equal to 0.015.

Next, we'll use the formula: Sales Price = Commission Amount / Commission Rate.

So, the sales price of the car can be found by dividing $397.50 by 0.015, which equals $26,500.

Final answer:

The mean of two numbers is 2.5, indicating that their sum is 5, which gives several possibilities about the individual numbers. The true statements based on the mean could be that one of the numbers is less than 2 or exactly 2.5.

Explanation:

If the mean of two numbers is 2.5, this means when we add those two numbers together and divide by 2 (because there are two numbers), the result is 2.5. To find what is true about the data based on this information, let’s examine each provided option:

a) Both numbers are greater than 5: This cannot be true; if both numbers were greater than 5, their mean would be greater than 5.

b) One of the numbers is less than 2: This statement can be true; for instance, if one number was 1 and the other was 4, the mean would be 2.5.

c) One of the numbers is 2.5: This can also be true; if one number is 2.5 and the other is any number that, when averaged with 2.5, results in 2.5, it would work (for example, 2.5 and 2.5).

d) The sum of the data is not divisible by 2: This is false; since the mean is 2.5 and there are two numbers, the sum must be 5, which is divisible by 2.

So the correct answer is b) and possibly c), meaning one of the numbers is less than 2 or one of the numbers could be exactly 2.5.

78/6=13

Each student will receive 13 buttons provided six students collected 10, 14, 15, 12, 13, and 14 buttons respectively and they divided the buttons evenly so that each student receives the same number of buttons. This can be obtained by adding to find total number of buttons and dividing by total number of students, that is 6.

Given that, six students collected 10, 14, 15, 12, 13, and 14 buttons respectively.

Therefore total number of buttons, 10+14+15+12+13+14 =78 buttons.

Number of buttons each student will get,78 buttons/6 students =13 buttons

Hence each student will receive 13 buttons provided six students collected 10, 14, 15, 12, 13, and 14 buttons respectively and they divided the buttons evenly so that each student receives the same number of buttons. The correct answer is option 3.
