Firlakuza [10]2 years ago

Answer:

B. The domain for f(x) is the set {-2, -1, 0, 1, 2, 3, 4, 5, 6}

D. f(-1) = 6

Step-by-step explanation:

The question gives a table marking the different coordinate pairs for a function, where f(x) is y. The top row represents the x-values and the bottom row represents the y-values.

Domain

The domain of a function is the set of x-values that the graph covers. In this case, the x-values are all integers between -2 and 6. We can see this in the top row of the table. Answer choice B best represents this domain.

Solving for F(x)

F(x) represents a specific y-value, for example, f(-1) represents the y-value when x = -1. So, to test choice D, we need to find what y-value matches -1 on the table. The table shows that when x = -1, f(x) = 6. This means that answer choice D must be correct.

<h2>Part 1)</h2>

Let's analyze each part of the function:

FROM x = 0 TO x = 5:

We can find the equation of this line by using The Slope-Intercept Form of the Equation of a Line, that states:

The \ graph \ of \ the \ equation: \\ \\ y=mx+b \\ \\ is \ a \ line \ whose \ slope \ is \ m \ and \ whose \ y-intercept \ is \ (0, b)

So the y-intercept here is (0,4) and m=\frac{4}{5}, therefore:

\boxed{y=\frac{4}{5}x+4}

FROM x = 0 TO x = 5:

From the previous line, we know that at x=5 the output is:

y=\frac{4}{5}x+4 \\ \\ y=\frac{4}{5}(5)+4 \\ \\ y=4+4=8

So the point P_{1}(5,8) lies on both lines.

For this new line, the slope is m=-\frac{3}{5}

So, with the Point-Slope Form of the Equation of a Line we can find the equation of this other line:

The \ equation \ of \ the \ line \ with \ slope \ m \\ passing \ through \ the \ point \ (x_{1},y_{1}) \ is:\\ \\ y-y_{1}=m(x-x_{1})

So:

y-8=-\frac{3}{5}(x-5) \\ \\ y=8-\frac{3}{5}x+3 \\ \\ \boxed{y=-\frac{3}{5}x+11}

The graph is shown below.

<h2>Part 2)</h2>

The graph of the linear function f(x)=ax+b is a line with slope m=a and y-intercept at (0,b). From the items, we can assure that the following equations are linear functions:

\bullet 3y=2x-1.5 \ because \ y=\frac{2}{3}x-\frac{1}{2} \\ \\ \\ \bullet y=1 \ because \ y=m(0)+1 \\ \\ \\ \bullet 5(x+y)=-25 \ because \ 5x+5y=-25 \ \therefore 5y=-5x-25 \therefore y=-x-5

In conclusion, the other functions are nonlinear and they are:

\bullet \ y=x^2+3 \\ \\ \bullet \ y=x^3 \\ \\ \bullet \ y=12-x^2

The cost of having a package delivered has a base fee of $10.80. Every pound over 5 lbs cost an additional $0.41 per pound. Writ
denis-greek [22]
<h3>Answer:</h3>

c. C = 0.41(w - 5) + 10.8

<h3>Explanation:</h3>

(w - 5) will represent the number of pounds over 5. For example, for a weight of 6 pounds, 6-5 = 1 is the number of pounds over 5.

The cost is $0.41 for each pound over 5, so that cost can be represented by ...

... 0.41(w - 5)

This charge is in addition to the base charge of $10.80, so the total cost will be ...

... C = 0.41(w - 5) + 10.80

On december 31, there were 40 units remaining in ending inventory. these 40 units consisted of 5 from january, 6 from february,
worty [1.4K]

Answer:

$5,675

Step-by-step explanation:

Answer:

Step-by-step explanation:

Calculation for the cost of the ending inventory using specific identification method.

Using this formula

Cost of ending inventory =

(January units ×January cost) +( February units ×February cost) + (May units × May cost) + (September units ×September cost) + (November units × November cost)

Cost of ending inventory =

January 5 units ×$116=$580

February 6 units ×$127=$762

May 10 units ×$139=$1,390

September 4 units ×$147=$588

November 15 units×$157=$2,355

Total =$5,675

Therefore the ending inventory using the specific identification method will be $5,675
