A function f is defined by f(x) = 3x + 1. Find
a. f(0)=
c. f(2)=
F(-2)

Answers

Answer:

a) f(0)=3*0+1 =0+1= 1

b)f(2)=3*2+1=6+1=7

c)f(-2)=3*(-2)+1=-6+1=-5

Answer:

Step-by-step explanation:

f(x) = 3x+1

f(0) = 3x + 1

f(0) = 3*0+1

f(0) = 0+1

f(0) = 1

f(2) = 3x+1

f(2) = 3*2+1

f(2) = 6+1

f(2) = 7

f(-2) =3x+1

f(-2) =3*-2+1

f(-2) = -6+1

f(-2) = -5

f(-2) =

Assume this is a partial list of financial highlights from a Best Buy annual report (dollars in millions):
Net sales
2020 - $40,580
2019 - $35,475

Earnings before taxes
2020 - $2,291
2019 - $1,313

Net earnings
2020 - $1,378
2019 - $921

Find horizontal analysis and vertical analysis.

Answers

You subtract $1313 from $2,291

Value of Horizontal Analysis:

⇒ Net sales = 14.4%

⇒ Earnings before taxes = 74.4%

⇒ Net earnings = 49.6%

Value of Vertical Analysis;

⇒ Net sales = 100%

⇒ Earnings before taxes = 5.6%

⇒ Net earnings = 3.4%

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Now, We can find as;

Horizontal Analysis:

Here, Calculate the dollar change by subtracting the previous year's figure from the current year's figure for each item:

Net sales = $40,580 million - $35,475 million

              = $5,105 million increase

Earnings before taxes = $2,291 million - $1,313 million

                                  = $978 million increase

Net earnings = $1,378 million - $921 million

                    = $457 million increase

Hence, Calculate the percentage change by dividing the dollar change by the previous year's figure and multiplying by 100 as;

Net sales = ($5,105 million / $35,475 million) x 100

               = 14.4% increase

Earnings before taxes = ($978 million / $1,313 million) x 100

                                  = 74.4% increase

Net earnings = ($457 million / $921 million) x 100

                   = 49.6% increase

And, Vertical Analysis:

Calculate the percentage of each item in relation to the net sales by dividing each item by the net sales and multiplying by 100:

Net sales = $40,580 million / $40,580 million x 100

               = 100%

Earnings before taxes = $2,291 million / $40,580 million x 100

                                  = 5.6%

Net earnings = $1,378 million / $40,580 million x 100

                    = 3.4%

Thus, Value of Horizontal Analysis:

⇒ Net sales = 14.4%

⇒ Earnings before taxes = 74.4%

⇒ Net earnings = 49.6%

Value of Vertical Analysis;

⇒ Net sales = 100%

⇒ Earnings before taxes = 5.6%

⇒ Net earnings = 3.4%

Helpp the topic is about limits

Answers

Since we want to find the value of k where the limit exists, set both equations equal to each other. Then substitute x = -1 in for each equation to find k.

[tex]kx - 3 = {x}^{2} + k[/tex]

1. Set both equations equal.

[tex] - k - 3 = 1 + k[/tex]

2. Substitute x = -1.

[tex] - 3 = 1 + 2k[/tex]

3. Solve for k by adding k to both sides. Continue the process of solving the equation.

[tex] - 4 = 2k[/tex]

[tex]k = - 2[/tex]

Thus, k = -2. Check by graphing the function.

Step-by-step explanation:

No doubt you have been shown at least a couple of different strategies for multiplying mixed numbers.

1) Use the distributive property.

  10(3 1/6) = 10(3) +10(1/6) = 30 +10/6 = 30 +5/3 = 30 + 1 2/3 = 31 2/3

2) Use improper fractions.

If you solve an equation by graphing each side separately, which of these is the solution to the equation?

A. the x-coordinate of the intersection point
B. the y-coordinate of the intersection point
C. both the x- and the y-coordinates of the intersection point
D. There is only a solution if the lines are identical.

Answers

9514 1404 393

Answer:

  A. the x-coordinate of the intersection point

Step-by-step explanation:

If you are solving ...

  f(x) = g(x)

the solution is one or more values of x. That is still true if you rewrite the equation to be a system of equations ...

  y = f(x)

  y = g(x)

The value of y tells you the value of each side of the original equation where the solution causes the functions to be equal. That is largely irrelevant. What you're looking for is the value of x.

The solution is the x-coordinate of the intersection point.
