This formula gives the yearly depreciation D for
an item in terms of its cost C, its salvage value
S, and the number of years 71. Solve the
equation below for C.
C-S
De

Answers

Answer:

C = 71D + S

Step-by-step explanation:

The computation of the equation for C is as follows:

Given that

Yearly Depreciation = D

Cost = C

Salvage value = S

Number of years = 71

Based on the above information

The formula for the yearly depreciation i.e. D is

D = (C - S) ÷ 71

71D = C - S

71D + S = C

So, the equation would be

C = 71D + S

A graph has average temperature (degrees Fahrenheit) on the x-axis, from 0 to 60, and total coat sales on the y-axis, from 0 to 100. A trend line goes through points (55, 50) and (65, 40). The regression equation is y = negative 0.96 x + 103.
Use the regression for Clothes-4-You coat sales to make predictions.

How many coats should Clothes-4-You expect to sell when the average temperature is 80°F?

What is the predicted temperature when 125 coats are sold?

Answers

Answer:

its 3 and 60 on edg

Step-by-step explanation:

Answer:

26 coats; -23°F temperature

Step-by-step explanation:

For x = 80, we have:

y = - 0.96*80 + 103 = 26.2 ≈ 26 coats expected to be sold

Predicted temperature when 125 coats are sold:

125 = - 0.96x + 103- 0.96x = 22x = 22/-0.96x = -22.9 ≈ -23°F  

Which is a correct expansion of the following expression?

18(x – 3) – 26


A. 18x – 80

B. 18x + 80

C. 18x + 28

D. – 62x

Answers

Answer:

A. 18x – 80

Step-by-step explanation:

18(x - 3) - 26

18x - 54 - 26

18x – 80

The answer is a. 18x - 80

Because first you will expand the brackets, for this you will multiply everything that is outside the bracket to what’s inside (18 times x) which will give you 18x and (18 times -3) which will give you -54

Now your equation will be

18x -54 - 26

Next you will workout the liked terms with are -54 and -26, since they are both negative just add them together and keep the sign.

To get your final answer

18x -80

The volume of a rectangular prism, with length l, width w, and height h, is given by the formula l×w×h. Suppose that you know that the height of a rectangular prism is 10 cm and that the volume is 100cm3. What are the possibilities for the other dimensions, l and W, of the prism? Give your answers as pairs of positive integers. I don't really understand what this question's trying to ask me. And I don't know the steps on how to calculate it.

Answers

Answer:

(100,1) (50,2) (25,4) (20,5) (10,10)

Step-by-step explanation:

Given

[tex]V = l * w * h[/tex]

[tex]h = 10cm[/tex]

[tex]V = 1000cm^3[/tex]

Required

Determine the possible values of l and w

We start by substituting 1000 for V and 10 for h in t he given formula

[tex]V = l * w * h[/tex]

[tex]1000 = l * w * 10[/tex]

Divide both sides by 10

[tex]100 = l * w[/tex]

Reorder

[tex]l * w = 100[/tex]

This implies that when the value of l and w are multiplied together, the result is always 100.

Possible values of (l,w) are: (100,1) (50,2) (25,4) (20,5) (10,10) and many more

For first term 6, the second term is 4·6 = 24.

For 2nd term 24, the third term is 4·24 = 96.

For 3rd term 96, the fourth term is 4·96 = 384.

Find the slope between the points (3, 0) and (5, 4).
A. 2
B. 12
C. 4

Answers

Answer: I would say A tbh thank you

Step-by-step explanation:

The coordinates of two points on the line, use the slope formula to determine the slope of the line.

The slope between the points (3, 0) and (5, 4) exists 2.

What is meant by slope of the equation?

Given the coordinates of two points on the line, use the slope formula to determine the slope of the line.

The slope formula, or the ratio of the change in the y values to the change in the x values, is

[tex]$m=\frac{y_ 2-y _1}{x _2-x _1}$$[/tex]

where [tex]$(x _1, y_ 1)$[/tex]and [tex]$(x_ 2, y _2)$[/tex] are two points that lie on the line.

Let the points be [tex]&(x _1, y _1)[/tex] = (3, 0) and [tex]$&(x _2, y _2)[/tex] = (5, 4)

The equation be [tex]$m=\frac{y_ 2-y _1}{x _2-x _1}$$[/tex]

substitute the values in the above equation, we get

[tex]$m=\frac{4-0}{5-3}=\frac{4}{2} \\[/tex]

The slope between the points (3, 0) and (5, 4) exists 2.

Therefore, the correct answer is option A. 2.

What is the solutions of the following system of equations.

y = -2x + 2

y = x - 1

Answers

Answer:

x = 1, y = 0

Step-by-step explanation:

Given the 2 equations

y = - 2x + 2 → (1)

y = x - 1 → (2)

Substitute y = x - 1 into (1)

x - 1 = - 2x + 2 ( add 2x to both sides )

3x - 1 = 2 ( add 1 to both sides )

3x = 3 ( divide both sides by 3 )

x = 1

Substitute x = 1 into either of the 2 equations for corresponding value of y

Substituting into (2)

y = 1 - 1 = 0

Solution is (1, 0 )
