The graph shows the cost of purchasing T-shirts. Find the constant rate of change for the graph. Then explain what points (0,0) and (1,9) represent

Answers

send a picture i need to see

Answer:

Constant rate of change is 9

Step-by-step explanation:

To find the constant rage of change we pick 2 points from the graph

points (0,0) and (1,9)

Rate of change is the slope

[tex]slope =\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]slope =\frac{9-0}{1-0}=9[/tex]

Slope = 9/1

Constant rate of change is 9

points (0,0) and (1,9) represent 9 units up from (0,0) and 1 units the right

A park district has 25 elm trees and 20 oak trees to be planted.They are separating the trees for different areas.They want each area to have the same number of elm trees and the same number of oak trees. What is the greatest number of areas that can be created?

Answers

The answer is 10 because

Answer: There are 5 number of areas that can be created.

Step-by-step explanation:

Since we have given that

Number of elm trees = 25

Number of oak trees = 20

According to question, They want each area to have the same number of elm trees and the same number of oak trees.

So, the greatest number of areas that can be created is H.C.F. of 25 and 20 = 5.

Hence, there are 5 number of areas that can be created.

Which ordered pair minimizes the objective function C = 60x + 85y?. (0, 160). (55, 70). (80, 50). (170, 0)

Answers

The ordered pair which minimizes the function C = 60x + 85y is ordered pair (80, 50). The correct answer between all the choices given is the third choice.

Step-by-step explanation:

The given objective function is [tex]C = 60x + 85y[/tex]

To check that which ordered pair is minimizing the objective function-we will substitute all the ordered pair one by one in the given function and we will calculate the value of C. The ordered pair which will give the minimum value will be the answer.

For (0, 160)

[tex]C=60\times 0+85\times 160=13600[/tex]

For (55, 70)

[tex]C=60\times 55+85\times 70=9250[/tex]

For (80, 50)

[tex]C=60\times 80+85\times 50=9050[/tex]

For (80, 50)

[tex]C=60\times 170+85\times 0=10200[/tex]

Hence the ordered pair which minimizes the objective function is (80, 50)

Name the property illustrated by the statement:

If d+1=f, then d=f-1 .

It's a property of equality, but I'm not sure which one. Please explain which one it is and why it's that one. Thanks! :-)

Answers

This is most likely the transitive property. The transitive property states a=b and b=c. which means a=c. It's merely stating that the functions are equal!!

Answer:

subtraction property of equality.

Step-by-step explanation:

IF any number is added on both sides of equation then it is addition property of equality.

If any number is subtracted from both sides of the equation then it is subtraction property of equality.

If d+1=f, then d=f-1 .

[tex]d+1=f[/tex]

To get 'd' alone , 1 is subtract from both sides

[tex]d=f-1[/tex]

1 is subtract from both sides of the given equation.

So it subtraction property of equality.

Cupcakes are packed 6 to a box. If Abby only buys full boxes of cupcakes give two possible numbers of cupcakes that she could buy.

Answers

6,12. if she bought 1 box thats 6 cupcakes, and if she bought 2 boxes then thats 12 cupcakes.

Answer:

The two possible numbers of cupcakes that she could buy can be 6,12,18 etc.

Step-by-step explanation:

As given:

Cupcakes are packed 6 to a box.

Abby only buys full boxes of cupcakes.

So, basically if she only wants full boxes, then she must get cupcakes in multiples of 6. Like : 6,12,18,24....

Therefore, any number that is a multiple of six is acceptable here.

Classify each pair of labeled angles as complementary, supplementary, or neither.

In this problem

Ballio has a reading goal. He checks 3 boxes of 9 books out from the library. After finishing them, he realizes that he beat his goal by 4 books! Label the tape diagrams to find Ballio's reading goal.

Answers

The number of books that Ballio was able to read can be determined by multiplying the number of boxes he checked out and the number of books per box. This is as shown below,
                     N = (3 boxes)(9 books/box)
                       N = 27 books

Since, it is stated that he beat his goal by 4 books, his goal is equal to the calculated number minus 4. 
               Goal = 27 books - 4 books
                Goal = 23 books

ANSWER: 23 books

PLEASE HELP!!!!this assignment was comparing the book to the movie of the glass castle, can someone please tell me if I have any mistakes!!!!The Glass Castle The movie version of The Glass Castle did a very good job of portraying the book. But, there are many differences and similarities from the movie version and the book version. In the movie version of the glass castle many details are left out. For example, in the book we are first are introduced to Jeannette as an adult in New York living in a high end apartment with her husband, but in the movie he was only her fianc. Also, in the book we only see adult Jennette in the beginning and the end of the book but but in the movie we jump back and forth from adult Jennette to child Jannette. Even though the movie was a little different from the book, there were many similarities. For example, in the book Jannette gets burned at three years old when she was cooking hot dogs all by her self, and that also happens in the movie. Another example is in both the movie and the book, Jannettes mom Rosemary, finds a ugly tree in the dessert that she decides to paint a portrait of it. The major theme of both the book and the movie is forgiveness, Everyone has something good about them, she said. You have to find the redeeming quality and love the person for that. / Oh yeah? I said. How about Hitler? What was he redeeming quality?/ Hitler loved dogs,Mom said without hesitation (Walls 144) In my opinion the book is better because it describes more details about the family, where they live, how they act, and the sequence of events. In the movie the character of Jeannette and her older sister Lori differ from the book because in the book they are more anxious to escape their crazy family and move to New York. In the book the plot does not differ from the movie. 3x+1/5y=7 solve for y.
