As you can see, the x axis stands for the weight, and the y axis the total cost.
You can see that the point, (1, 4) definitely exists.
So basically it would be 1 pound of cheese for four dollars, since x is weight and y is total cost.
You can see the fourth choice states that it's four dollars for one pound of cheese.
Hope this helped :)

A rug maker is using a pattern that is a rectangle with a length of 96 inches and a width of 60 inches. The rug maker wants to increase each dimension by a different amount. Let l and w be the increases in inches and the length and width. Write and simplify an expression for the perimeter of the new pattern.

Increasing the width by [tex]w[/tex], we have the new expression for the width as [tex]60+w[/tex]
Perimeter of a rectangle is given by adding all the sides, so we have
[tex]P = 96 + l+96+l+60+w+60+w[/tex]
[tex]P=192+2l+120+2w[/tex]

Solve for s.
2/3s+5/6s=21
Enter the answer, as a whole number or as a fraction in simplest form, in the box.
s =
Answers
If you do the problem without the variable the equation equals 1.5.
After I did that I divided 21 with 1.5 then it had come to a total of 14.
After that I decided to plug in 14 in the equation and the total came out to be 21.So s =14
To solve the equation 2/3s + 5/6s = 21, you first combine the fraction terms into 1.5s = 21, then solve for s by dividing both sides of the equation by 1.5, giving you s = 14.
Explanation:To solve for s, you need to first combine like terms on the left-hand side of the equation 2/3s + 5/6s = 21.
To add these fractions, you first need to find a common denominator, which is 6 in this case. So, the equation becomes 4/6s + 5/6s = 21, which simplifies to 9/6s = 21 or 1.5s = 21.
Now you can solve for s by dividing both sides of the equation by 1.5, resulting in s = 21 / 1.5.
So, the solution for s is 14, which can be entered as a whole number.

Describe why it might not be a good idea to use a key where each symbol stands for 1 in a picture graph
Answers
Final answer:
It is inefficient to use a key where each symbol represents the value 1 in a picture graph because it can make the graph cluttered and hard to interpret, especially with large data sets. Picture graphs should simplify visualization of data, yet remain clear and easily comprehensible.
Explanation:
Using a key where each symbol stands for 1 in a picture graph might not be a good idea because picture graphs are meant to represent larger sets of data visually and efficiently. If each symbol represents only 1, the graph could quickly become cluttered and hard to read, especially if the data set is large. This defeats the purpose of a picture graph, which is to provide a clear and simplified visual representation of the data. Moreover, the choice of symbols in a mathematical context is arbitrary; they are placeholders that have no intrinsic significance, and what matters is the concept they represent.
For instance, when dealing with large quantities, using symbols that represent 10, 100, or any other convenient large number makes the graph much more readable and helps to emphasize important relationships and comparisons between different data sets. Similarly, when using equations, symbols are used as stand-ins for numbers, and changing a symbol does not affect the underlying relationship they represent. Introducing more effective representations pictures the concept that equations capture. Likewise, the practicality of picture graphs can be compared to other types of graphs, like pie graphs, bar graphs, and line graphs, each of which serves a different purpose and has its own best use scenario.
Using a key where each symbol stands for 1 in a picture graph can make it cluttered and confusing, especially for large data sets. It is advisable to use symbols to represent larger values or to choose different types of graphs for readability and clear communication of the data's relationships.
Explanation:Using a key where each symbol stands for 1 in a picture graph could be inadvisable in some situations. For large quantities, having one symbol represent a single unit could make the graph cluttered and difficult to read. It is more effective to have symbols represent larger, rounded values so the graph remains clear and interpretable. The use of symbols in mathematics and graphs is generally arbitrary, and they can be chosen to best represent the data being visualized. For example, in equations or graphs illustrating one-dimensional kinematics, symbols are chosen to present information on position, velocity, and acceleration over time in a way that makes relationships between these physical quantities easily understandable.
When considering how to best display data, it's crucial to think about readability and the ease of extracting useful information from the graph. If a picture graph with one symbol representing 1 becomes too complex, it might be better to opt for other types of graphs like bar graphs or line graphs, depending on the data's characteristics. Furthermore, the real purpose of graphs is to capture and represent relationships or trends, which is often better achieved with symbols that represent more suitable quantities, especially when dealing with large numbers.
The glossary of key symbols and notation in mathematics reaffirms the concept that the symbols themselves are not inherently meaningful, but are placeholders to facilitate understanding of the relationships and quantities they represent. Therefore, when creating picture graphs, the key chosen should enhance the viewer's ability to quickly grasp the depicted information.

** u r basically multiplying that -8 by every term in the parenthesis...
(-8 * 5v) + (-8 * -x) + (-8 * -5) =
-40v + 8x + 40
The Distributive Property allows us to multiply the term outside of the parenthesis by all terms inside of the parenthesis.
Here’s an example;
2(1 + 3)
2(1) + 2(3)
2 + 6
8.
Hopefully this example and explanation has helped you understand the concept of using the Distributive Property.
Now, let’s apply this to our current expression.
-8(5v - x - 5)
Remember that when you multiply a negative by a positive, the product remains negative. When you multiply a negative by a negative, the product is positive.
-8(5v - x - 5)
-8(5v) = -40v
-8(-x) = 8x
-8(-5) = 40
Our product is:
-40v + 8x + 40

The cost C (in dollars) for the care and maintenance of a horse and carriage is C=15x+2000 where x is the number of rides.
Rides cost 35$
A: write an equation for the revenue R in terms of the number of rides
B: How many rides are needed to break even.
Need help with both parts
Answers
Answer: 100 rides are needed to break even.
Step-by-step explanation:
We have given the cost function
C(x)=15x+2000 where x is the number of rides.
And rides cost 35$
⇒ revenue function would be 35 times x
i.e.R(x)=35 x , where x is the number of rides.
Break even point of a firm occurs when at a certain point x the total cost equals to the total revenue.
i.e. at break even point
total revenue=total cost
⇒35x=15x+2000
⇒35-15x=2000[subtract 15x from both sides]
⇒20x=2000 [simplify]
⇒x=2000/20[dividing both sides with 20]
⇒x=100
∴ 100 rides are needed to break even.
The revenue function will be 35x and the breakeven point will be 100 rides.
From the information given, the revenue function will be calculated by multiplying the price by the quantity. This will be:
= 35 × x
= 35x
The breakeven point will be the point where total revenue equals the total cost. This will be:
35x = 15x + 2000
35x - 15x = 2000
20x = 2000
x = 2000/20
x = 100
Therefore, the revenue function will be 35x and the breakeven point will be 100 rides.

if 4 apples cost $3.04 how much does just one cost
Answers
So, we can assume all of the apples are the same price right? It doesn't matter about size or color because the problem doesn't tell us that. So, we can conclude one apple is the same prices as another.
Well, to figure out how much one apple costs, we can divide 3.04 by 4. This is because we have 4 apples so we can take that price of the 4 apples total and divide it by haw many apples the problem gives us.
So, 3.04 / 4 = .76

input values in the equation
4*10^5 = k/(4*10^-4) >>> k = 160 N
P = 160/w^2
it said if she wears a heel with a width of .5 cm
P = 160(0.5 * 10^-2)^2 >>> P = 6400 KPa

Answers
The word sentence that represents the equation 6(x + 3) = 42 is option A: The sum of 3 and six times some number is 42.
Explanation:The word sentence that represents the equation 6(x + 3) = 42 is option A. The sum of 3 and six times some number is 42.
To understand why, let's break down the equation step-by-step:
We have the expression (x + 3) in parentheses, which means that whatever number the student chooses to replace x with should be added to 3.Next, we multiply the entire expression (x + 3) by 6.The result of that multiplication should equal 42.So, option A correctly expresses the equation by stating that the sum of 3 and six times some number is 42.
