A graph of the system of inequalities is shown in the image attached below.

The region that represents the combinations of balloons and streamers that Tamara can purchase is the shaded region that contains the point (1, 3).

In order to write a system of linear inequalities to describe this situation, we would assign variables to the number of packages of balloons and number of streamer rolls respectively, and then translate the word problem into algebraic equation as follows:

Since one package of balloons costs $4.50 and streamers are $1.50 per roll, and Tamara wants to spend no more than $15 on decorations, a linear inequality to describe this situation is given by:

4.50x + 1.50y ≤ 15.

Additionally, Tamara knows she will be buying at least 2 rolls of streamers;

y ≥ 2

In order to finish the task in the allotted time, you would therefore need to ascend more quickly or decide to only climb the first two walls.

The Latin term minute, which means "small," is the root of both the adjective instant (my-NOOT), which denotes something that is incredibly small, and the substance minute (MIN-it), which denotes 60 seconds of time. Although the two terms have different pronunciations, they both refer to small sizes.

We can compute the overall time needed to scale all three barriers and compare it to the time available, which is 71/2 minutes or 450 seconds, to determine if you have enough time.

One wall takes 155 seconds to scale, so climbing three walls would take:

3 walls x 155 seconds per wall = 465 seconds

You wouldn't have enough time to scale all three walls inside the allotted time restriction because 465 seconds is longer than the amount of time that is accessible, which is 450 seconds.

Answer:  The height of the tree is approximately 44 ft.

Step-by-step explanation:  Step 1: Calculate the ratio of the person's height to the length of their shadow.

Person's Height: 5 ft

Length of Shadow: 4 ft

Ratio: 5 ft/4 ft = 1.25

Step 2: Use the ratio to calculate the length of the tree's shadow.

Length of Tree's Shadow: 22 ft

Ratio: 1.25

Calculation: 22 ft/1.25 = 17.6 ft

Step 3: Multiply the length of the tree's shadow by the ratio to calculate the tree's height.

Length of Tree's Shadow: 17.6 ft

Ratio: 1.25

Calculation: 17.6 ft x 1.25 = 22 ft

Answer: The height of the tree is approximately 44 ft.

The conversion from pounds (lb) to kilograms (kg) is determined by multiplying the weight in pounds by 0.45359237. The formula to convert pounds to kilograms is kg = lb x 0.45359237.

To calculate the weight of 205 pounds in kilograms, the calculation is as follows: kg = 205 lb x 0.45359237 = 92.98 kg.Therefore, the weight of 205 pounds is equal to 92.98 kilograms. This calculation can also be used to convert any weight in pounds to its equivalent in kilograms. For example, to convert 500 pounds to kilograms, the calculation would be: kg = 500 lb x 0.45359237 = 226.79 kg.This calculation can be used to convert any weight in pounds to its equivalent in kilograms. It is important to remember that the formula must be used correctly and that all units must be consistent.

Step-by-step explanation:

We would expect to see around 200 fewer accidents per year among 16-year-old drivers in your state if the proposal to increase the permit period from 6 to 12 months is implemented.

Estimation is the process of determining an estimate or approximation, which is a value that can be used for a specific purpose even when the input data is incomplete, uncertain, or unstable.

It is difficult to predict exactly how many fewer accidents would occur as a result of increasing the time a driver must hold a learner's permit from 6 to 12 months. However, there is evidence to suggest that longer permit periods can result in fewer accidents, as novice drivers have more time to gain experience under supervision before obtaining a full license.

According to research by the Insurance Institute for Highway Safety, increasing the permit period from 6 to 12 months could lead to a 20% reduction in crash rates among 16-year-old drivers.

Assuming this reduction holds true in your state, we can estimate the number of accidents that would be prevented by multiplying the current number of accidents involving 16-year-old drivers (let's assume 1,000 per year) by 20%, or 0.2. This gives us an estimated reduction of 200 accidents per year.

Yes, the inverse of a matrix exists if the determinant of the matrix is -13.

What is a matrix?

Linear equations are expressed using matrices, which are ordered rectangular arrays of numbers. Columns and rows make up a matrix. Mathematical operations like addition, subtraction, and matrix multiplication can also be done on matrices. If there are m rows and n columns, the matrix is represented as m × n matrix. The inverse of a matrix is available only for square matrices.

Now the determinant is a value that is associated with a square matrix.

The product of all the elements in any row or column and their corresponding co-factors is the determinant of a matrix.

For an inverse matrix to exist, the determinant of the matrix should not be zero. This is because the determinant of the inverse matrix is the inverse of the determinant of the original matrix.

If the determinant is zero, then the determinant of the inverse matrix will be 1/0, which is undefined.

So, as long as the determinant is not equal to zero, the inverse matrix exists.

Therefore the inverse of a matrix exists if the determinant of the matrix is -13.

Answer: No, the area will not stay the same.

The new area is smaller than the old area.

========================================================

Explanation:

Let's look at an example.

Consider a 10 by 30 rectangle. Its area is 10*30 = 300 square units.

Now let's change the length and width.

The rectangle is now 12 by 24. The new area is 12*24 = 288 square units.

In summary:

This is one counterexample, of infinitely many, that proves the area does not stay the same. Instead, the area shrinks.

-----------------

This section will go over a more formal proof using algebra.

old area = length*width = LW

Let's say the length increases by 20% and the width decreases by 20%.

Then,

new area = (new length)*(new width)

new area = (1.20L)*(0.80W)

new area = (1.20*0.80)*(LW)

new area = 0.96*(LW)

new area = 0.96*(old area)

This shows that the new area is 96% of the old area. There has been a 4% reduction (since 100% - 96% = 4%)

Notice how 96% of 300 = 0.96*300 = 288. See the previous section above.

We cross multiply

[tex]8x = (760)(100)[/tex]

[tex]8x = 76000[/tex]

Last but not least, we divide by 8 on both sides

Two distinct but related concepts are referred to by the phrase "linear function": A polynomial function of degree zero or one that has a straight line as its graph is referred to as a linear function in calculus and related fields.

Here, we have

Given: Yvette is saving money to buy holiday gifts. She will save the money she makes at her part-time job. However, she borrowed $25 from her sister which she has to pay back before she can start saving.

Let the linear function that models the given situation be y = ax + b. Here, a and b are constants.  We can use this information to find the values of a and b.

We put x = 0 and y = -25 into y = ax + b

b = -25

Substitute the value of b into y = ax + b

y = ax -25...(1)

Now we put x = 4 and y = 14 in equation(1) and we get

14 = 4a - 25

4a = 39

a = 9.75

Substitute the value of a in equation (1):

y = 9.75x - 25

Compare the above function with the slope-intercept form of a line y = mx + c

m = 9.75, c = -25

Hence, the slope of the line is 9.75 and the y-intercept is -25.

A. From the previous calculations, it is clear that the slope of the line is 9.75. Hence, the first statement is not true.

B. From the given table, it is known that person Y had started working with -25 dollars. Clearly, 9.75 is the slope of the line, but it does not represent the initial amount that person Y had at x = 0. Hence, the second statement is not true.

C.  From the previous calculations, it is clear that the y-intercept is -25, not 0. Hence, the third statement is not true.

D. From the previous calculations and the given table, it is clear that the y-intercept is -25, and it does represent the initial amount that person Y had at x = 0. Note that the y-intercept is negative as the person has borrowed 25 dollars from her sister. Hence, the fourth statement is true.

E. From the previous calculations, it is clear that the slope of the line is 9.75. It is known that the slope of a line represents the rate of change in the value of y with respect to x. So, it can be concluded that 9.75 represents the amount that person Y earns per hour. Hence, the fifth statement is true.
