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)




An example of consecutive odd integers is 23, 25, 27, and 29. Find four consecutive odd integers with sum of 160. Show your work. After completing the problem, write out the steps, in words, that you used to solve the problem.??????????????Please write the steps to so I can understand Please...Thankyou

Answers

To find the off integers that add to 160, first divide 160 by 4 to get 40. Now you know the four numbers will be around 40, which means that two of the number will be less than 40 and two will be greater than 40. Since they have to be odd, consecutive integers, you know that the four number are 37,39,41,43. To check your work, add the numbers together to get 160. :)

37, 39, 41, and 43. The least is 37, and the greatest is 43. :)

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

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

Drag and drop the choices into the boxes to correctly complete the table. Each pair of angles may belong to more than one category.

Answers

Answer:

The table in the attached figure

Step-by-step explanation:

we know that

If the sum of two angles is equal to [tex]90\°[/tex] then the angles are complementary

If the sum of two angles is equal to [tex]180\°[/tex] then the angles are supplementary

In this problem

[tex]61\°+29\°=90\°[/tex] ------> the angles are complementary

[tex]90\°+89\°= 179\°[/tex] -------> neither (not complementary, not supplementary)

[tex]63\°+47\°= 110\°[/tex] -------> neither (not complementary, not supplementary)

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

write an expression to represent the perimeter of the figure below. rectangle with 2x-3 and x+2

Answers

Hi there! 

The perimeter is when you add all the sides of a shape. In a rectangle, two sides are the same, and so are the other two. So, if the two sides are 2x-3 and x+2 the expression will be: 

2(2x-3) + 2(x+2) 

If we were to simplify this, it would be 

4x-6+2x+4 
6x-2

Hope this helps!

An expression to represent the perimeter of the rectangle with 2x-3 and x+2 would be 6x-2.

What is simplification of an expression?

Usually, simplification involves proceeding with the pending operations in the expression.

Simplification usually involves making the expression simple and easy to use later.

The perimeter is when you add all the sides of a shape.

In a rectangle, two sides are the same, and so are the other two. therefore, if the two sides are 2x-3 and x+2 the expression will be:

2(2x-3) + 2(x+2)

If we were to simplify this, it would be;

4x-6+2x+4

6x-2

Hence, An expression to represent the perimeter of the rectangle with 2x-3 and x+2 would be 6x-2.

 The slope is -2.
Hope this helps!

Final answer:

The slope of the line described by the equation y = -2x is -2. This indicates that the line has a negative slope, decreasing 2 units on the y-axis for every increase of 1 unit on the x-axis.

Explanation:

The slope of a line is a measure of its steepness, typically represented by the symbol 'm' in the equation of a straight line, y = mx + b, where 'm' is the slope and 'b' is the y-intercept. To calculate the slope of a line given points on a graph, we use the formula slope = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two distinct points on the line. For the given line y = -2x, which is already in slope-intercept form, the slope 'm' is directly provided as -2. No calculation is needed since the equation itself indicates that the slope is -2, meaning for every increase of 1 on the x-axis, there is a decrease of 2 on the y-axis.

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.
