The blueprint dimensions of a building that is 70 feet × 90 feet is: 4.375 inches X 5.625 inches.

Scale refers to the ratio or proportion between the dimensions of an object or a system in the real world and its representation in a model, drawing, or map. A scale is typically expressed as a ratio or a fraction, such as 1:100 or 1/4, which indicates the relationship between the size of the object in the real world and the size of its representation in the model or drawing.

Using a scale of 1 inch : 16 feet means that every inch on the blueprint represents 16 feet in the actual building. To find the blueprint dimensions of a building that is 70 feet x 90 feet, we need to divide each dimension by 16.

The blueprint dimensions are:

70 feet ÷ 16 = 4.375 inches

90 feet ÷ 16 = 5.625 inches

Therefore, the blueprint dimensions of the building are approximately 4.375 inches by 5.625 inches.

The answer is: 4.375 inches X 5.625 inches.

An equation passing through the points (2, 13) and (2, -11) is x = 2.

The equation of a line can be written in the form of y = mx + b, where m is the slope and b is the y-intercept.

To find the equation of the line that goes through the given points, we first need to find the slope. The slope can be calculated using the formula:

[tex]\[m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\][/tex]

Plugging in the given points, we get:

[tex]\[m = \frac{-11 - 13}{2 - 2} = \frac{-24}{0}\][/tex]

Since the denominator is 0, the slope is undefined. This means that the line is vertical. A vertical line has the equation x = a, where a is the x-coordinate of any point on the line. Since both of the given points have the same x-coordinate of 2, the equation of the line is x = 2.

The composite result function ( g o f )(x) in the functions f(x) = x² - 3 and g(x) = 2x - 1 is 2x² - 7.

A function is simply a relationship that maps one input to one output.

Given the data in the question;

First, set up the composite result function (g o f)(x).

(g o f)(x) = g( f(x) )

g( x )  = 2x - 1

g( f(x) ) = 2( f(x) ) - 1

g( f(x) ) = 2( x² - 3 ) - 1

Now, simplify the function by applying distributive property.

g( f(x) ) = 2( x² - 3 ) - 1

g( f(x) ) = 2 × x² - 2 × 3 - 1

g( f(x) ) = 2x² - 6 - 1

Add -6 and -1

g( f(x) ) = 2x² - 7

Therefore, the function operation ( g  o f ) is 2x² - 7.

The final factored form of the polynomial is b(a-b) and the category of the remaining polynomial is a binomial.

The first step in factoring out the GCF from the polynomial ab+ay-b^(2)-by is to identify the greatest common factor of all the terms. In this case, the GCF is b. Once we have identified the GCF, we can factor it out from each term by dividing each term by the GCF. This gives us:

ab+ay-b^(2)-by = b(a+y)-b(b+y) = b(a+y-b-y)

Next, we can simplify the remaining polynomial by combining like terms:

b(a+y-b-y) = b(a-b)

Finally, we can identify the category of the remaining polynomial. Since it has two terms and each term has a degree of 1, the remaining polynomial is a binomial.

To show that the system AX = B is equivalent to the upper-triangular system UX = Y and find the solution, we need to use the Gaussian elimination method. The Gaussian elimination method is a process of reducing a system of linear equations to an equivalent upper-triangular system.

Step 1: Write the given system of equations in matrix form:
```
| 2 -2  5 |   | x1 |   |  6  |
| 2  3  1 | * | x2 | = | 13  |
|-1  4 -4 |   | x3 |   |  3  |
```
Step 2: Use the Gaussian elimination method to reduce the matrix to an upper-triangular form:
```
| 2 -2  5 |   |  6  |
| 0  7 -9 | = |  7  |
| 0  0 9/7|   | 18/7|
```
Step 3: Write the upper-triangular system in equation form:
```
2x1 - 2x2 + 5x3 = 6
0x1 + 7x2 - 9x3 = 7
0x1 + 0x2 + 9/7x3 = 18/7
```
Step 4: Solve the system using back substitution:
```
x3 = 18/7 * 7/9 = 2
x2 = (7 + 9*2)/7 = 4
x1 = (6 + 2*2 - 5*2)/2 = 1
```
Step 5: Write the solution in vector form:
```
| x1 |   | 1 |
| x2 | = | 4 |
| x3 |   | 2 |
```
Therefore, the solution to the system AX = B is x1 = 1, x2 = 4, and x3 = 2.

Here is a table showing the relationship between the number of coins collected and the total points earned:

Number of coins (c) Total points (p)

2 35

3 50

4 65

5 80

6 95

7 110

8 125

9 140

10 155

To graph these ordered pairs, we can plot the number of coins collected (c) on the x-axis and the total points earned (p) on the y-axis. Then we can plot each ordered pair as a point on the graph and connect the points with a line. The resulting graph should show a linear relationship between c and p, with a slope of 15 and a y-intercept of 0.

Analyzing the graph, we can see that as the number of coins collected increases, the total points earned also increases at a constant rate. This suggests that collecting coins is an important part of the game, as it significantly increases the player's total score. Additionally, the slope of the line (15) tells us that each additional coin collected is worth 15 points, while reaching the next level is worth only 5 points.

Shea needs to do 600 carpet cleaning per year to break even.

What is revenue?

Total revenue is the total amount of money earned by a business from the sale of its products or services during a particular period of time.

To break even, the total revenue Shea generates from the carpet cleaning business must be equal to the total cost of running the business.

Let's first calculate the total cost of running the business per year:

Total Cost = Fixed Costs + Variable Costs

Since the fixed plus variable costs per month total $1,500, the total cost per year would be:

Total Cost = $1,500 x 12

Total Cost = $18,000

Now, let's calculate the profit that Shea makes per cleaning:

Profit per Cleaning = Price per Cleaning - Cost per Cleaning

Profit per Cleaning = $60 - $30

Profit per Cleaning = $30

So, Shea makes a profit of $30 per cleaning.

To break even, the total profit generated by the number of cleanings Shea does per year should be equal to the total cost of running the business per year:

Total Profit = Total Revenue - Total Cost

If x is the number of carpet cleaning Shea needs to do per year to break even, then:

Total Revenue = Price per Cleaning x Number of Cleanings per Year = $60x

Total Profit = Profit per Cleaning x Number of Cleanings per Year = $30x

Setting Total Profit equal to Total Cost:

$30x = $18,000

x = $18,000 / $30

x = 600

Therefore, Shea needs to do 600 carpet cleaning per year to break even.

The solution to this linear programming problem is (x,y) = (3,4) and f = 22.

To solve this linear programming problem, we need to find the feasible region by graphing the constraints and then use the objective function to find the maximum value of f.

1. Graph the constraints:

x + y ≤ 7 can be rewritten as y ≤ -x + 7
2x + y ≤ 12 can be rewritten as y ≤ -2x + 12
y ≤ 4

2. Find the feasible region:

The feasible region is the area that satisfies all of the constraints. In this case, it is the area bounded by the three lines and the x and y axes.

3. Use the objective function to find the maximum value of f:

f = 2x + 4y

To find the maximum value of f, we need to find the corner points of the feasible region and plug them into the objective function. The corner points are (0,4), (3,4), and (4,3).

f(0,4) = 2(0) + 4(4) = 16
f(3,4) = 2(3) + 4(4) = 22
f(4,3) = 2(4) + 4(3) = 20

The maximum value of f is 22 at the point (3,4).

We also note that the coefficients of 'e' are identical, so we can eliminate 'e' as a variable by subtracting one equation from the other. We choose to subtract the equation with the lower value coefficient of 'd'.

  (d +e) -(-d +e) = (1) -(-5)

  2d = 6 . . . . . . . simplify

  d = 3 . . . . . . . . divide by 2; matches the solution above.

The attached graph uses x and y, because those are the built-in independent and dependent variables. Your graphing calculator may let you define the variables as you wish.
