The table represents the function f(x).

Answer:

(-7, -10)

Step-by-step explanation:

Solve for x and y in double variable equation

y = 2x + 4

y = x - 3

y = x - 3, plug in to first equation

x - 3 = 2x + 4

x = -7

y = -7 - 3

y = -10

(-7, -10)

By solving a linear equation, we will see that after 3 hours, both companies will charge the same amount.

We know that company A charges $200 plus $50 per hour. So if they work for x hours, they charge:

A(x) = $200 + $50*x

And company B charges $125 plus $75 per hour, so if they work for x hours, they charge:

B(x) = $125 + $75*x

We want to find the value of x such that A(x) = B(x), then we want to solve the linear equation:

$200 + $50*x = $125 + $75*x

$200 - $125 = $75*x - $50*x

$75 = $25*x

$75/$25 = x = 3

This means that after 3 hours, both companies will charge the same amount.

Answer: The value of x is 3.5

Explanation:

Equation:

y = 2x - 7

When the equation's Line intersects the x-axis, the value of y shall be always 0

Insert y = 0, to find x intercept

⇒ 0 = 2x - 7

⇒ 2x - 7 = 0

⇒ 2x = 7

⇒ x = 3.5

So coordinates: (x, y) → (3.5, 0)

The reasonable domain of the function is [0,4)

The function of the car value is given as:

V(x) = 20000 * (0.84)^x

When the car reaches half its value, we have:

V(x) = 10000

Substitute V(x) = 10000 in V(x) = 20000 * (0.84)^x

10000 = 20000 * (0.84)^x

Divide both sides by 20000

0.84^x = 0.5

Take the logarithm of both sides

x log(0.84) = log(0.5)

Divide both sides by log(0.84)

x = 4

This means that the maximum value of x is 4

Hence, the reasonable domain of the function is [0,4)

Answer:

  54 chickens

Step-by-step explanation:

This problem requires you find the area of Thomas's field, then use that area to find the number of chickens he can keep. The irregularly-shaped field can be considered as composed of shapes that you know how to find the area of.

__

There are many ways the area can be divided. One of them is shown in the attachment. That shows the area to be the sum of the areas of a triangle and a trapezoid.

The triangle has a base of 20 m and a height of 7 m, so an area of ...

  A = 1/2bh

  A = 1/2(20 m)(7 m) = 70 m²

The trapezoid has bases of 11 m and 18 m, and a height of 14 m. Its area is ...

  A = 1/2(b1 +b2)h

  A = 1/2(11 m +18 m)(14 m) = 1/2(29 m)(14 m) = 203 m²

The area of the field is the sum of these areas:

  field area = triangle area + trapezoid area

  field area = 70 m² +203 m² = 273 m²

__

Each chicken requires an area of 5 m², so the total area for n chickens is ...

  area for n chickens = 5n . . . . square meters

This area cannot exceed the area of the field, so an inequality can be written:

  area for n chickens ≤ field area

  5n ≤ 273

  n ≤ 54.6 . . . . . . divide by 5

Thomas can keep a maximum of 54 chickens in the field.

Answer: [tex]y\leq -3x-3[/tex] [tex]< --Graph[/tex]

In order to graph the equation "y ≤-3x - 3", we need to graph the inequality by finding the boundary line, then shading the appropriate area.

Answer:d.33

Step-by-step explanation: To begin we convert his living room floor length and width to inches. 8 1 slash 3 feet = 100 inches
10feet= 120 inches

hence the area in square inches of the living room floor is 100 inches times120 inches = 12000 inches squared.

Each carpet tile has an area of 20 by 20 which = 400inches squared. dividing the area of the living room by 400inches of each carpet tile, would yield 30 carpet tiles needed to cover this area.

As per linear equation, the minimum number of carpet tiles that Aurelio must purchase to cover the area of his living room floor is 29.

A linear equation is an equation that has one or multiple variables with the highest power of the variable is 1.

Given, the room has a length of 10 feet = 12 × 10 inches = 120 inches

The width of the room is = 8 feet = 12 × 8 inches = 96 inches

Therefore, the area of the room is

= 120 × 96 square inches

= 11520 square inches

Length of each carpet tile is 20 inches

Width of each carpet tile is 20 inches

Therefore, the area of each tile is

= (20)² square inches

= 400 square inches

The number of tiles require

= (11520/400)

= 28.8

≈ 29

Therefore, 29 tiles will be required.

Answer:

x = 36; y = 9

Step-by-step explanation:

To solve this problem you need to set up two equations. The first equation comes from the first sentence "One number is 4 times another." This equation can be written as x = 4*y where x and y are the two numbers. The second equation comes from the second sentence "Their difference is 27." This equation can be written as x-y = 27. To find the numbers you need to rearrange one equation and plug it into the other.

Step 1: write equations

x = 4*y

x-y = 27

Step 2: rearrange

Not necessary here

Step 3: substitute in

x - y = 27

4y -y = 27

3y = 27

y = 9

Step 4: solve for x

x = 4*y

x = 4*9

x = 36

[tex]x[/tex] - one number

[tex]4x[/tex] - the other number

[tex]4x-x=27\\3x=27\\x=9\\\\4x=4\cdot9=36[/tex]

For this exercise, the graph of a logarithmic function is shown in the image attached below.

A logarithmic function is a type of function that graphically represents the inverse of an exponential function. Mathematically, a standard logarithmic function is written as [tex]y = log_nx[/tex].

In Mathematics, the domain of any logarithmic function is from (x > 0) to infinity (+∞). Thus, its graph moves to the right on the vertical axis and it increases to infinity (+∞) as the value of x increases.

In this scenario, an image of all the graphs wasn't provided, so, I would proceed to add an attachment to illustrate the graph of a logarithmic function.
