Step-by-step explanation:

To solve the system of equations:

3x + 4y = 17 (equation 1)

-4x - 3v = -18 (equation 2)

We can use either the substitution method or the elimination method. Here, we will use the elimination method to eliminate one of the variables.

Multiplying equation 1 by 4 and equation 2 by -3, we get:

12x + 16y = 68 (equation 3)

12x + 9v = 54 (equation 4)

Subtracting equation 4 from equation 3, we get:

7v = 14

Dividing both sides by 7, we get:

v = 2

Substituting v = 2 into equation 4, we get:

12x + 9(2) = 54

12x + 18 = 54

12x = 36

x = 3

Substituting x = 3 into equation 1, we get:

3(3) + 4y = 17

9 + 4y = 17

4y = 8

y = 2

Therefore, the solution to the system of equations is (3, 2).

The width and perimeter of his field will be 67.4 feet and 198.8 feet, respectively.

Given that:

Area, A = 2,156.8 square feet

Length, L = 32 feet

Assume L is the length and W is the width. Then the area is given as,

A = L × W

The width of the rectangle will be calculated as,

2,156.8 = 32W

W = 67.4 feet

And the perimeter is calculated as,

P = 2(32 + 67.4)

P = 198.8 feet

The drawing's scale factor is 7/36, which is a simplified fraction.

The scale factor of Kevin's drawing is the ratio of the length in the drawing to the actual length. We are given that the scale he used was 7 inches = 1 yard. Since 1 yard is equal to 3 feet, which is equal to 36 inches, we can write:

1 yard = 36 inches

Therefore, the scale factor is:

drawing length / actual length = 7 inches / 36 inches

Simplifying, we get:

drawing length / actual length = 7/36

Therefore, the drawing's scale factor is 7/36, which is a simplified fraction

Here are the solution steps to determine x and y values

Given equations are

[tex]\begin{amatrix}x-2y=-13 \dots [1] \\\\ y=-2x-6\dots\dots[2]\end{amatrix}[/tex]

In equation [2] get all the variables to the left side and the constant on ther right side:

Let's examine equations [1] and [3]:

I'm sorry! Although, I cannot perform the physical measurements required for this project, I can provide some guidance on how to approach the project.

Part One of the project involves measuring the heights and arm spans of 11 people, in addition to your own measurements. If you do not have access to 11 people to measure, you can use the sample data provided in the table.

Part Two of the project involves creating a scatter plot of the data using graphing software of your choice. You should also predict the line of best fit and sketch it on your graph.

Part Three of the project involves analyzing the scatter plot and the line of best fit. You will need to determine which variable should be plotted on the x-axis and which should be plotted on the y-axis. You should also write the equation of the line of best fit using the slope-intercept form of the line y = mx + b and explain what the slope and y-intercept represent within the context of your graph.

Additionally, you will need to test the residuals of two other points to determine how well the line of best fit models the data, use the line of best fit to describe the data correlation, and use the line of best fit to approximate the height of a person with a given arm span and vice versa.

Make sure to follow the rubric provided and include your scatter plot and answers to the questions in a word processing document.

The perimeter of the gray rectangle, given that both rectangles have the same area, is 48 inches

First, find the area of the first rectangle by the formula :

= Length x Width

= 9 x 12

= 108 inch ²

This means that the perimeter of the gray rectangle is 108 inch ² as well. The missing dimension would be:

Area = Length x Width

108 = Length x 18

Length = 108 / 18

Length = 6 inch

The perimeter is then :

= 18 + 18 + 6 + 6

Using the logarithm quotient rule, it can be simplified to log1 - logA. Since log1 = 0 for any base, this simplifies further to -logA.

We simplify and solve the given expressions using the mentioned terms. Here are the step-by-step explanations for each expression:

1. logA: This expression represents the logarithm of a number A to a specified base. Without any base provided, it cannot be simplified further.

2. 1logAA: Since the coefficient of the logarithm is 1, this simplifies to logAA, which represents the logarithm of A to the base A. By definition, logAA = 1.

3. logA x Blog (a/b): This expression seems to have formatting issues, so I'll break it down into two separate expressions: - logA x B: This represents the logarithm of the product AB to a specified base. Using the logarithm product rule, it can be simplified to logA + logB. - log (a/b): This represents the logarithm of the quotient a/b to a specified base. Using the logarithm quotient rule, it can be simplified to loga - logb.

4. log A ^ B: This expression represents the logarithm of A raised to the power of B to a specified base. Using the logarithm power rule, it can be simplified to B * logA. 5. log 1/A: This expression represents the logarithm of the reciprocal of A (1/A) to a specified base.

Using the logarithm quotient rule, it can be simplified to log1 - logA. Since log1 = 0 for any base, this simplifies further to -logA.

Answer: 41800, 7.6555%

Step-by-step explanation:

The laptop sold for 45000 nu with a markup of 3200 nu.

This means the price of the laptop was (45000-3200) nu before the markup, or 41800 nu.

To find the mark-up percent, divide 3200 by 41800.

That will give you a percent of 7.6555

To double check that this is correct, multiply 41800 by 1.076555, and you'll get 45000 nu.

Answer: 9 pages in the photo album will be completely filled.

Step-by-step explanation:

To determine how many pages of the photo album will be completely filled, we need to divide the total number of pictures by the number of pictures per page:

73 pictures ÷ 8 pictures per page = 9.125

Since we can't have a fraction of a page, we need to round up to the nearest whole number.

9.125 rounded to the nearest whole number is 9.

The first three terms of the sequence are 9, 18 and 27

An arithmetic sequence is simply defined in algebra as a sequence of numbers where the difference between every two consecutive terms is the same.

From the information given, we have that;

The nth term of the sequence is given with the equation,

an = 3(3)n​

For the first term, we have that n = 1

Substitute the values

a1 = 3(3)1

expand the bracket

a1 = 9

for the second term, n = 2

Substitute the value

a2 = 3(3)2
