Answer 1

Answer: 1/3

Step-by-step explanation:

(1,5) will be x1 (1) and y1 (5)

(4,6) wil be x2 (4) and y2(6)

knowing this, you plug in the numbers into the formula

6-5 = 1

4-1 = 3

m= 1/3

Answer 2

Answer: [tex]\frac{1}{3}[/tex]

Step-by-step explanation: It's actually pretty simple to find the slope. y2 is the second y point and y1 is the first y point (same goes for x). So in this case, y2 = 6, y1 = 5, x2 = 4, x1 = 1. So once you have that, you would do this: [tex]\frac{6-1}{4-1}[/tex] subtract both equations and you'd get: [tex]\frac{1}{3}[/tex]

Hope this helped you and use this for future reference!

Which of the following equations are equivalent? Select three options. 2 + x = 5 x + 1 = 4 9 + x = 6 x + (negative 4) = 7 Negative 5 + x = negative 2

Answers

Answer:

Please mark me the brainliest

Step-by-step explanation:

The three equivalent equations are:

1. Negative 5 + x = negative 2

2. 2 + x = 5

3. x + 1 = 4

Explanation:

1. Negative 5 + x = negative 2 can be solved by adding 5 to both sides, which gives x = 3.

2. 2 + x = 5 can be solved by subtracting 2 from both sides, which gives x = 3.

3. x + 1 = 4 can be solved by subtracting 1 from both sides, which gives x = 3.

Therefore, the three equivalent equations are those where x = 3. The other equation, 9 + x = 6, can be solved by subtracting 9 from both sides, which gives x = -3, and is not equivalent to the other three equations. Similarly, x + (negative 4) = 7 can be solved by adding 4 to both sides, which gives x = 11, and is also not equivalent to the other three equations.

Answer: Negative 5 + x = negative 2 2 + x = 5 x + 1 = 4

Find the domain and range of the
radical function: f(x)= -√x +1

(radical is only over the x and NOT over the 1).

1. x≤ 0 and y> 1
2. x>0 and y < 1
3. x ≥ 0 and y≤ 1
4. x>0 and y≥ 1

Answers

f(x)= -√x +1x4 which would give you 99

The domain of a radical function is the set of all real numbers for which the radicand (the expression under the radical) is greater than or equal to zero, since the square root of a negative number is not a real number. In this case, the radicand is x, so we need to have x ≥ 0 for the function to be defined.

Therefore, the domain of the function f(x) = -√x + 1 is x ≥ 0.

To find the range of the function, we can consider the behavior of the function as x approaches infinity and as x approaches zero. As x approaches infinity, -√x approaches negative infinity, so -√x + 1 approaches negative infinity + 1 = -∞. As x approaches zero from the right, -√x approaches 0, so -√x + 1 approaches 1.

Therefore, the range of the function is y ≤ 1.

So, the correct option is 3. x ≥ 0 and y ≤ 1.

0.14285714285 as a fraction

Answers

The number 0.14285714285 is a recurring decimal, which means that it repeats infinitely. To express it as a fraction, we can use the following method:

Let x = 0.14285714285

Then, we can multiply both sides of this equation by a power of 10 to eliminate the decimal:

10x = 1.4285714285

Now we can subtract the left-hand side of the equation from both sides:

10x - x = 1.4285714285 - 0.14285714285

Simplifying the right-hand side of the equation gives:

9x = 1.285714285

Finally, we can solve for x by dividing both sides of the equation by 9:

x = 1.285714285 / 9

Simplifying the right-hand side of the equation gives:

x = 0.1428571428...

We can see that this is exactly the same as the original number we started with. Therefore, we can substitute the value of x into the equation we set up earlier:

x = 0.14285714285 = 1.285714285 / 9

Therefore, 0.14285714285 expressed as a fraction is:

1.285714285 / 9

The number 0.14285714285 can be expressed as the fraction [tex]1.4285714285 / (10^n - 1),[/tex]

We have,

To express the decimal number 0.14285714285 as a fraction, we can follow these steps:

Step 1:

- Let x be the decimal number.

x = 0.14285714285

Step 2:

- Let's multiply both sides of the equation by 10^n, where n is the number of decimal places in the repeating part of the decimal.

[tex]10^n \times x = 10^n \times 0.14285714285[/tex]

Step 3:
- Subtract the original equation from the equation obtained in Step 2 to eliminate the repeating part.

[tex]10^n \times x - x = 10^n \times 0.14285714285 - 0.14285714285[/tex]

Simplifying this equation, we have:

[tex](10^n - 1) \times x = 1.4285714285[/tex]

Step 4:

- Divide both sides of the equation by (10^n - 1) to solve for x.

[tex]x = 1.4285714285 / (10^n - 1)[/tex]

Thus,

The number 0.14285714285 can be expressed as the fraction [tex]1.4285714285 / (10^n - 1),[/tex]

Where n represents the number of decimal places in the repeating part of the decimal.

The population of the West was about 53 million in 1990. The population of this area increased an average of about 1 million a year during the 1990s. What is the equation?

Answers

Answer:

Let P be the population of the West in a certain year, and t be the number of years after 1990.

Since the population increased by about 1 million a year during the 1990s, we can model the population as:

P = 53 + 1t

where 53 represents the population of the West in 1990 and 1 represents the average increase in population per year.

So for example, in 1992 (two years after 1990), the population of the West would be:

P = 53 + 1(2) = 55 million

Similarly, in 1995 (five years after 1990), the population of the West would be:

P = 53 + 1(5) = 58 million

And so on for any year t after 1990.

Answer:Let P be the West's population in a given year and t represent the number of years after 1990.We may model the population as follows because it grew by roughly 1 million people year in the 1990s:P = 53 + 1twhere 53 is the Western region's 1990 population, and 1 is the average annual population growth.Thus, for instance, the population of the West in 1992 (two years after 1990) would be:P = 53+1(2) = 55,000,000Similarly, five years later, in 1995, the West's population would be as follows:P = 53 + 1(5) = 58,000,000for each year t that comes after 1990, etc. I need brainliest PLEEEASEE

Edgar measures the temperature of a solution at the beginning of an experiment to be 23°F. He monitors the temperature of the solution every minute for 10 minutes. He records the change in temperature from his previous reading. His data show a decrease of 2°F four times, a decrease of 3°F three times, no temperature change two times, and an increase of 6°F once.

(a) Write an expression that represents the average change in temperature each minute.

(b) Edgar repeats the experiment and finds the average change in temperature each minute is greater in the second trial than in the first trial. What is the average change in temperature each minute in the second trial of the experiment? Show your work.

Answer:

Answers

To find the average change in temperature each minute in the first trial of the experiment, we need to add up all of the temperature changes Edgar recorded and divide by the number of temperature changes he recorded. We can represent this with the following expression:(2 degrees F x 4) + (3 degrees F x 3) + (0 degrees F x 2) + (6 degrees F x 1) / 10 temperature changes= 8 degrees F + 9 degrees F + 0 degrees F + 6 degrees F / 10 temperature changes= 23 degrees F / 10 temperature changes= 2.3 degrees F/minute This means that the average change in temperature each minute in the first trial of the experiment was 2.3 degrees F.To find the average change in temperature each minute in the second trial of the experiment, we need to determine the average change in temperature each minute in the second trial. This value will be greater than 2.3 degrees F, since the average change in temperature each minute was greater in the second trial than in the first trial. However, we do not have any information about the specific temperature changes Edgar recorded in the second trial, so it is not possible to calculate the average change in temperature each minute in the second trial.

Numbers 2-3 =

2. For number 2, the only thing we need to do is multiply fractions. Before we multiply fractions, we have to turn a mixed fraction into improper by doing the denominator (3) multiplied by the whole number (2) then added to the numerator (1). After that, 2 1/3 should equal to 7/3 as our improper fraction. Now just multiply 7/3 by 2/5 to get your answer.

7/3 x 2/5 = 14/15 hours on Tuesday

3. This question is similar to the previous one. Convert mixed into improper then multiply.

Option (A) The first theme park had about 5 times as many guests than the second.

Step-by-step explanation:

Number of guests in the First Theme Park = 2 * 10^7

= 2 * 10 * 10 * 10 * 10 * 10 * 10 * 10

= 20 * 100 * 100 * 100

= 2000 * 10000

= 20000000

Number of guests in the Second Theme Park = 4 * 10^6

= 4 * 10 * 10 * 10 * 10 * 10 * 10

= 4 * 100 * 100 * 100

= 400 * 10000

= 4000000

Now we can observe that, the number of guests in the First Theme Park is more than the number of guests in the Second Theme Park.

Let’s start dividing to find how many times the First Theme Park has more guests than the Second Theme Park.

Number of guests in the First Theme Park = 20000000

Number of guests in the Second Theme Park = 4000000

Number of times, the First Theme Park has more guests than the Second Theme Park = 20000000/4000000

= 2000000/400000

= 200000/40000

= 20000/4000

= 2000/400

= 200/40

= 20/4

= 5 times

Francisco wants to find the product of 382 trays of apples and the 18 apples that fit in each tray. He decides to find the answer by breaking 18 into equal parts: 9 and 9. He says that if he multiplies 382 by 9 and then multiplies the product by 9 again, he can find the answer.
Will Francisco’s strategy work? Why or why not?

Answers

Answer:

Please mark me the brainliest

Step-by-step explanation:

Yes, Francisco's strategy will work.

Breaking 18 into 9 and 9 means that he is using the distributive property of multiplication, which states that a(b+c) = ab + ac. In this case, he is breaking 18 into 9 and 9, so he can rewrite the product of 382 trays and 18 apples as:

382 trays x (9 apples + 9 apples)

Using the distributive property, this can be expanded as:

(382 trays x 9 apples) + (382 trays x 9 apples)

This simplifies to:

3,438 trays x 9 apples

Which gives the correct answer of 30,942 apples. Therefore, Francisco's strategy works because he correctly applied the distributive property of multiplication to break down the problem into simpler parts.

Yes Francisco’s strategy will work.

Use your equation to determine the initial cost to the company, in dollars.

Initial cost to the company $ __

(The equation is c=5.25t-75.)

Answers

Answer: The initial cost to the company is $-75.

Step-by-step explanation:

To determine the initial cost to the company using the equation provided (c = 5.25t - 75), we need to understand what each variable represents:

c: The cost to the company in dollarst: The time (usually measured in hours, days, or weeks)

Since the initial cost refers to the cost at the beginning (t = 0), we can plug t = 0 into the equation and solve for c:

c = 5.25(0) - 75

c = 0 - 75

c = -75

In this context, the initial cost to the company is $-75. It might seem unusual for the cost to be negative; however, this could be interpreted as the company having an initial credit or saving of $75 before any time has been spent on the project. Please note that the specific interpretation of this negative value depends on the context of the problem and the real-world situation being modeled by the equation.

The initial cost to the company would be -$75 I think it’s right but sorry if it’s wrong
