Since we are using graphs, we will do not need to algebraically solve this system of equations.

When you graph a system of equations, the solution is always the point at which the two lines intersect.

Here is our system of equations graphed. We see that the lines intersect at about (1 1/3, 2 1/3). Therefore, the correct answer is C. x=1 1/3, y=2 1/3

1.  T5s = (1.08x10¹³ cm * (6.96x10⁵⁰ cm² / dVenus²))0.25 2. This

discrepancy is due to the greenhouse effect on Venus, where the thick

atmosphere traps heat and causes a much higher temperature. 3. TSS =

(1.08x10¹³ cm * (6.96x10⁵⁰ cm² / (2.28x10 cm)²))0.25. 4. different from the

observed subsolar.

1. To calculate T5s for Venus, we can use the formula

T5s = (\(Vermes * (r^{2} / dVenus^2))^{0.25}\).

Plugging in the given values, we have

T5s = (1.08x10¹³ cm * (6.96x10⁵⁰ cm² / dVenus²))0.25.

2. The measured surface temperature on Venus is around 700 K, which is significantly higher than the calculated T5s.

This discrepancy is due to the greenhouse effect on Venus, where the thick atmosphere traps heat and causes a much higher temperature.

3. Using the formula TSS = (\(Vermes * (r^2 / dMars^2))^{0.25}\),

we can calculate TSS for Mars. With the given average distance of Mars from the Sun (2.28x10 cm),

we have TSS = (1.08x10^13 cm * (6.96x10⁵⁰ cm² / (2.28x10 cm)²))0.25.

4. The calculated TSS for Mars is likely to be different from the observed subsolar temperature of Martian soil (300 K).

This difference can be attributed to various factors, such as the greenhouse effect, atmospheric composition, and surface conditions.

5. The greenhouse effect on Mars and Venus has distinct impacts on their surface temperatures.

While the subsolar surface temperature on Mars is relatively pleasant, the average temperature across the planet is about 212 K, well below the freezing point of water (273 K).

In contrast, Venus experiences a much higher average temperature due to the extreme greenhouse effect, resulting in surface temperatures of around 700 K.

6. The presence of extensive polar caps of frozen water and CO2 on Mars suggests that liquid water could have existed on the planet in the past.

One possible explanation is that Mars underwent climate changes, causing the frozen water and CO2 to melt and form liquid water.

However, further research is needed to fully understand the mechanisms behind the presence of liquid water on Mars in the past.\

The Cholesky decomposition of the identity matrix is simply the identity matrix itself

The Cholesky decomposition of the identity matrix is simply the identity matrix itself. To see why this is the case, recall that the Cholesky decomposition of a matrix A is a lower-triangular matrix L such that

A = LL^T.

When A is the identity matrix I, we have I = LL^T.

Since L is lower-triangular, its transpose L^T is upper-triangular. Therefore, the only way for LL^T to be the identity matrix I is for L to also be the identity matrix I.

In summary, the Cholesky decomposition of the identity matrix I is I itself.

She should multiply 1.09 in her current balance by to find her total balance in a year in one step.

In the given question, Salma invests money in an account paying a simple interest of 9% per year.

No money will be added or removed from the investment so we have to find what should she multiply in her current balance by to find her total balance in a year in one step.

For 9% simple interest.

For $100 we get interest of $9 and total money became $109.

Here the factor is (109/100) = 1.09

This can be read as "the cost of making x gift baskets is greater than 6 dollars" during inequality.

Both mathematical phrases, equations and inequalities, are created by connecting two expressions. The equal sign (=) indicates that two expressions in an equation are believed to be equivalent. The characters >,,, or indicate that the two expressions in an inequality are not always equal.

The equation-like form of the formula 5x 4 > 2x + 3 has an arrowhead in lieu of the equals sign. It is an illustration of inequity. This shows that the left half, 5x 4, is bigger than the right part, 2x + 3.

Let x be the number of gift baskets Mae wants to make. Then, the total amount of money she will spend can be expressed as 15.50x.

Step-by-step explanation:

because we can also find out the value of x in second equation like this

3x=21

x=21/3

x=7

Answer:

We conclude that x = 7 must be true for the second equation because it will also satisfy the second equation.

Step-by-step explanation:

Given the first equation

solving the equation

3x-5 = 16

adding 5 to both sides

3x-5+5 = 16+5

3x = 21        ∵ 3x = 21 is the 2nd equation      

divide bothe sides by 3

3x/3 = 21/3

x = 7

Please notice that when simplifying 3x-5 = 16, the moment we reach 3x=21, we can determine that it represents the same equation.

In other words, whatever the value of x we will get, it will satisfy both equations.

Therefore, we conclude that x = 7 must be true for the second equation because it will also satisfy the second equation.

Verification:

Consider the 2nd equation

3x = 21

Put x = 7

3(7) = 21

21 = 21

Thus, it has been validated that when we conclude that x = 7 must be true for the second equation because it will also satisfy the second equation.

The given system is the system of two equations.

What is the system of linear equations?

A system of linear equations is a set of two or more linear equations that contain two or more variables. These equations are often used to model real-world situations and to find the values of the variables that make all the equations in the system true.

The tables of ordered pairs represent the points on the graphs of lines q and v. From the tables, we can see that line q can be represented by the equation y = 3x + 9 and line v can be represented by the equation y = -x + 10. Therefore, the system of equations represented by lines q and v is:

y = 3x + 9

y = -x + 10

We can also write these equations in the form of Ax + By = C :

3x + y = 9

-x + y = 10

Where A, B, and C are constants.

It's a system of two equations with two variables, x and y.

Hence, the given system is the system of two equations.

There is no point of discontinuity for the limits.

The following are the limits of a function and its discontinuity point/s:Limit Evaluations:a) To compute the limit lim (2x + 5x – 3)/ (x-3), first simplify the expression: (2x + 5x – 3)/ (x-3) = (7x-3)/ (x-3)

A key idea in mathematics is the limit, which is used to describe how a function behaves as its input approaches a certain value or as it approaches infinity or negative infinity.

Therefore, \(lim (2x + 5x - 3)/ (x-3)\)as x approaches 3 is equal to 16.

b) To compute the limit lim x-2, notice that it represents the limit of a function that is constant (equal to 1) around the point 2. Therefore, the limit is equal to 1.

c) To compute the limit\(lim 2x'-5x-12/x-4x\) as x approaches 4, first simplify the expression: 2x'-5x-12/x-4x = (x-6)/ (x-4)Therefore, lim 2x'-5x-12/x-4x as x approaches 4 is equal to -2.

d) To compute the limit lim \(X(X lim 5-4x)\), notice that it represents the product of the limits of two functions. Since both limits are equal to 0, the limit of their product is equal to 0.

e) To compute the limit \(5x-3x2+6x-4/2\), first simplify the expression: 5x-3x2+6x-4/2 = -3/2 x2 + 5x - 2

The sine function to find the ratio of the length of the side opposite the given angle to the length of the hypotenuse. Therefore, b ≈ 2.07, c ≈ 8.2266, and B ≈ 82.78°.

We are given the values of one angle and one side of the triangle, so we can use the sine function to find the ratio of the length of the side opposite the given angle to the length of the hypotenuse.

Then we can use that ratio to find the lengths of the other two sides of the triangle. Using the given values, we have:

sin A = opposite / hypotenuse

sin 15° = b / 8b = 8 sin 15° ≈ 2.07

To find c, we can use the Pythagorean theorem:c² = a² + b²c² = 8² + 2.07²c² ≈ 67.6449c ≈ √67.6449 ≈ 8.2266 (rounded to four decimal places)

To find B, we can use the sine function again:

sin B = opposite / hypotenuse

sin B = c / 8B = arcsin(c / 8)

B ≈ 82.78° (rounded to two decimal places)

Therefore, b ≈ 2.07, c ≈ 8.2266, and B ≈ 82.78°.

The solution to the system of equations y = 1.5x - 4 and y = -x  is (1.6,-1.6). The correct answer is D.

The solution to the system of equations can be calculate as follows

From the question we can conclude that the equations are :

y = 1.5x - 4

y = -x

to find the value of x and y  we can substitute y = -x in the first equation so it became

-x = 1.5x - 4

-1.5x - x = -4

-2.5x = -4

x = 1.6

after we found the value of x we can find the value of y by Substitute

x = 1.6 in y = -x

y = -1.6

Therefore, the solution to the y = 1.5x - 4 and y = -x  is (1.6,-1.6).

A dollar is further divided into some majorly used parts as:

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

For this case, we're specified that:

Suppose that she has got 'x' nickles.

Then, as it is given that she has 2 more nickles than dimes, therefore, we get:

number of nickles = 2 + number of dimes

x = 2 + 12 = 14

Thus, Alice has got  12 dimes and 14 nickles.

Similarly, we have:

Thus, the total amount of money she got is $1.2 + $0.7 = $1.9

To find the mean absolute deviation (MAD) of a dataset,

Calculate the mean (average) of the dataset.

Find the absolute difference between each data point and the mean.

Calculate the mean of these absolute differences.

Calculate the mean,

Mean

= (4.8 + 5.9 + 6.2 + 10.8 + 1.2 + 6.4) / 6

= 35.3 / 6

= 5.88 (rounded to two decimal places)

Find the absolute difference between each data point and the mean,

|4.8 - 5.88| = 1.08

|5.9 - 5.88| = 0.02

|6.2 - 5.88| = 0.32

|10.8 - 5.88| = 4.92

|1.2 - 5.88| = 4.68

|6.4 - 5.88| = 0.52

Calculate the mean of these absolute differences,

MAD

= (1.08 + 0.02 + 0.32 + 4.92 + 4.68 + 0.52) / 6

= 11.54 / 6

= 1.9233 (rounded to four decimal places)
