Answer:

90

Step-by-step explanation:

If you take 9 pictures on each page that is gonna be its own number so you than add 6 and 4 and get ten than multiply it by 9 and boom you get 90

Carli has a total of 90 pictures in her photo book, with 54 pictures from her trip to Fort Lauderdale and 36 pictures from her trip to Las Vegas.

In order to find the total number of pictures in Carli's photo book, we need to calculate the number of pictures on each page for both trips and then sum them up. Carli put 9 pictures on each page. She filled 6 pages with pictures of her trip to Fort Lauderdale, so the number of pictures for this trip is 6 pages x 9 pictures per page = 54 pictures. Carli also filled 4 pages with pictures of her trip to Las Vegas, so the number of pictures for this trip is 4 pages x 9 pictures per page = 36 pictures. The total number of pictures in her photo book is 54 pictures + 36 pictures = 90 pictures.

y - 2x = 1

6x - y = 7

Adding equations,

y = 2x + 1 = 5

Answer: (2,5)

Check:

5-2(2)=1, good

6(2)-5=7, good

To solve the system of equations y - 2x = 1 and 6x - y = 7, we use the elimination method. By aligning the equations and setting the right sides equal, we can solve for 'x' and then 'y', resulting in the solution x = 2 and y = 5.

Solving the System of Equations

To solve the system of equations:

y - 2x = 1

6x - y = 7

We can use the method of substitution or elimination. In this case, the elimination method seems efficient. Let's align the equations:

y = 2x + 1

6x - y = 7

We can eliminate y by adding the two equations. First, rearrange the second equation:

y = 2x + 1

y = 6x - 7

By setting the right sides equal to each other, we get 2x + 1 = 6x - 7. Solving for x gives us x = 2 and substituting x back into either equation yields y = 5.

Therefore, the solution to the system of equations is x = 2 and y = 5.

Answer:

A = (800 yd - x)x, [0, 800]

Step-by-step explanation:

The farmer fences in this rectangular garden using 1600 yds of fencing.  Using the formula for the perimeter of a rectangle,

P = 2x + 2L, where x is the width and L is the length.  Here P = 1600 yd.

Solving for L:  1600 yd = 2x + 2(L) →  800 yd = x + L  →  L = 800 yd - x.

The area of the rectangle is A = L·x.  Subbing (800 yd - x) for L, we get:

A = (800 yd - x)x.  This is the desired formula for the area of the rectangle as a function of x alone.  Neither length nor width can be negative, so the domain of this function A is x ≤ 800 yd.

Let the length of the rectangular garden = l yards

And the width of the garden = w yards

Farmer has the fence in length = 1600 yards to cover all the sides of the garden

Therefore, Perimeter of the rectangular garden = 1600 yards

Since, perimeter of the rectangular garden is given by the expression,

Perimeter = 2(l + w)

By substituting the values in the expression,

1600 = 2(l + x)

l + x = 800

l = 800 - x -------(1)

Since, area of the rectangle = Length × Width

                                                = l × w

                                                = lx

Therefore, by substituting the value of 'l' in terms of 'x' in from equation (1),

Area of the rectangular garden = (800 - x)x

If the area of the garden is represented by by the function A(x),

A(x) = (800 - x)x

A(x) = 800x - x²

Since, Area can not be negative or zero,

Domain of the function will be 0 < x < 800

| 4 | x

| 12 | y

| 5 | z

After reducing the matrix in row-echelon form we are left with three equation as following

Equation 1

0x + 0y + 1z = 5

Equation 2

0x + y1 + 2z = 12

Equation 3

A debt greater than Carol's would bear a value that is numerically larger but still under the negative sign. In simpler terms, any debt greater than -$130 is indeed a greater debt.

The question asks, 'Which of the following account balances represents a debt greater than Carol's?' When working with debts in math, it's important to remember that the larger the number, the greater the debt. So any number larger than -$130 represents a debt greater than Carol's.

For example, a balance of -$150 would be a larger debt than Carol's -$130. Why? Because when you owe $150, it's more than owing $130, despite the negative sign. Conversely, a balance of -$100 would be less of a debt than Carol's, because owing $100 is less than owing $130.

It's a somewhat counterintuitive part of working with negative numbers, but once you understand that the negative sign represents a debt, it starts to make sense. The concept of debt here is similar to examples provided where people often have a tendency to hold onto a savings account while carrying a credit card debt.

Final answer:

A real-world population growth graph may differ from a game's graph in terms of actual population numbers, reflecting real-life constraints versus game assumptions, although the overall S-shape indicating logistic growth may be similar. This shows the importance of graph type and display in interpreting growth rates and relationships in data.

Explanation:

When comparing a graph of a scientist’s data on population growth to a graph representing population growth in a game, there may be notable differences. The x-y values on the graphs indicating the time frames for the growth curves would generally be the same since time is a consistent measure. However, while the overall S-shape of a logistic growth model might be similar, representing the slowdown in growth as the population reaches carrying capacity, the actual population numbers corresponding to the starting populations could differ based on real-world limitations versus game conditions.

Further, displaying data graphically helps in interpreting growth rates and relationships between data points. For instance, in a scenario where an individual receives a $2 raise each year, the growth rate decreases over time unless the raise amount also increases. In terms of graphing, economists and other professionals use various types of graphs like pie charts or bar graphs to visualize data, such as the distribution of hours played amongst students, or the comparison of populations among countries. The choice of the graph type and how it's displayed can impact the interpretation of the data.

Moreover, when comparing real data with that from a game, the assumptions and simplifications made in a game's model might not perfectly reflect real-life complexities, leading to different population growth dynamics and consequently different shapes of the graph beyond just the starting population numbers.

B. He multiplied the dividend by 100 instead of 10.

Step-by-step explanation:

Chen had to divide [tex]1.926[/tex] by [tex]0.9[/tex]. To make it easier to divide, he thought of multiplying both the dividend and the divisor by 10.

Chen multiplied the divisor by 10 but mistakenly multiplied the dividend by 100 instead of 10.

So his whole division problem was changed.

Therefore, the correct answer option is B. He multiplied the dividend by 100 instead of 10.

Answer:

option B

He multiply the dividend by 100 instead of 10

Step-by-step explanation:

Given that,

divisor  = 0.9

dividend = 1.926

Chen decided to multiply each by 10 to get

divisor  = 0.9 x 10 = 9

dividend = 1.926 x 10 = 19.26

but unfortunately he multiply the dividend by 100

As,

1.926 x 100 = 192.6

So,

Chen's error was that he multiply the dividend by 100 instead of 10.
