Use the graph of the function to find its domain and range. Write the domain and range in interval notation

Hello!

We have two different scenarios that we have to solve in the question. We will be solving for both the x and y variable.

We were given the equation: -3y + 2x = -18

To solve for our variables, we will use the values given in our question.

Solve:

Lets solve for the value "y", where our x = 0

Plug in 0 to x and solve:

-3y + 2(0) = -18

-3y = -18

y = 6

Lets now solve for the value "x", where our y = 0

Plug in 0 to y and solve:

-3(0) + 2x = -18

2x = -18

x = -9

Therefore, our answers would be: y = 6, x = -9

Answer:

y = 6

x = -9

Answer:

Step-by-step explanation:

you multiple each hight and base

Amiya + Ravi = 72

x + 2x = 72

3x = 72

x = 72/3

x = 24

therefore Amiya has 24 stamps

Step-by-step explanation:

Step-by-step explanation:

we need 2 1/2 × 2 = 5 cubes along the length.

1 1/2 × 2 = 3 cubes along the the width.

and 1 1/2 × 2 = 3 cubes along the height.

altogether we need

5×3×3 = 45 cubes

and the volume is

2 1/2 × 1 1/2 × 1 1/2 = 5/2 × 3/2 × 3/2 = 45/8 = 5 5/8 yd³

There are 96 cubes are there for each of the length, width, and height of the prism.

The volume of a rectangular prism is 12 yd³.

A prism is a three-dimensional solid object in which the two ends are identical. It is the combination of flat faces, identical bases, and equal cross-sections.

A rectangular prism has a length of 2 1/2yd, a width of 1 1/2yd, and a height

of 1 1/2yd.

length 2 1/2 and half yd​ = 2 1/2+ (1/2) yd = 5/2 + 1/2 = 6/2= 3 yd

Width 1 1/2 and half yd​ = 1 1/2 + (1/2) yd = 3/2 + 1/2 =  (4/2) = 2 yd

Height 1 1/2 and half yd = 1 1/2 + (1/2) yd = 3/2 + 1/2 =  (4/2) = 2 yd

Cubes of edge length (1/3) yd are used to fill the rectangular prism.

The length would contain (3) ÷ (1/2) = 6

The width would contain (2) ÷ (1/2) = 4

The height would contain (2) ÷ (1/2) = 4

How many cubes are there for each of the length, width, and height of the prism?

6 × 4 × 4 = 96 cubes

There are 96 cubes are there for each of the length, width, and height of the prism.

What is the volume of the prism?

The volume of rectangular prism = 3 × 2 × 2 = 12

The volume of a rectangular prism is 12 yd³.

The value of the composite function f(x) . g(x) is 77x^7  + 78x^6 - 27x^5

The functions are given as:

f(x) = 11x^3 - 3x^2

g(x) = 7x^4 + 9x^3

The value of f(x) . g(x) is calculated as:

f(x) . g(x) = (11x^3 - 3x^2) *  (7x^4 + 9x^3)

Expand

f(x) . g(x) = 77x^7  + 99x^6 - 21x^6 - 27x^5

Evaluate the like terms

f(x) . g(x) = 77x^7  + 78x^6 - 27x^5

Hence, the value of the composite function f(x) . g(x) is 77x^7  + 78x^6 - 27x^518x^5

Answer: 55 [tex]\frac{5}{9}[/tex] feet² or 55.556 feet²

Step-by-step explanation:

      The scale means that for ever one in the scale drawing, it is 20 in the actual room. We will convert the dimensions using proportions.

  [tex]\frac{5}{x}=\frac{1}{20}[/tex]

  100 = x

-> The length is 100 inches

  [tex]\frac{4}{x}=\frac{1}{20}[/tex]

  80 = x

-> The width is 80 inches

    The area of a rectangle can be found by multiplying the length by the width:

A = L * W

A = 100 * 80

A = 8,000 inches²

  To get this into square feet, we will divide by 144. Why? There are 12 inches in a foot. 12 times 12 is 144.

8,000 inches² / 144 = 55 [tex]\frac{5}{9}[/tex] feet²

            The area of the room, in square feet, is 55 [tex]\frac{5}{9}[/tex] feet².

Answer: c = about 7.21

Step-by-step explanation:

ok - pythagorean theorum

6^2+4^2=C^2

36 + 16 = c^2

52 = c^2

root both sides

c = about 7.21

The solution to the equation 6^2 + 4^2 = C^2 is approximately 7.21

The equation is given as:

6^2 + 4^2 = C^2

Evaluate the exponents of 6 and 4

36 + 16 = C^2

Evaluate the sum

52 = C^2

Take the square root of both sides

7.21 = C

Rewrite as:

C = 7.21 (approximated)

Hence, the solution to the equation is approximately 7.21

The marginal cost is the change in the total cost that arises when the quantity produced is incremented, the cost of producing additional quantity.

a). First construct total variable cost for each level Q -- simply multiply Q by AVC. So

Q TVC

1 1

2 4

3 9

4 16

5 25

6 36

Now calculate marginal cost as the change in TVC for each level Q.

Q MC

1 1

2 3

3 5

4 7

5 9

6 11

b) with price = 10, firm will produce 5 but not 6 units.

c) calculate total profits at Q=5. Total revenue is $50, total costs is $25+$16 = $41. Since there are profits to be made, more firms will enter, shifting the supply curve out, Price will fall, quantity goes up. Each firm will supply the same or less as price falls.

If the measure of angles ∠DAB = 51° and the value of x is 25. Then the measure of angle ∠CAB will be 25°.

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

If the measure of angles ∠DAB = 51°, ∠CAB = x, and ∠DAC = x + 1.

Then the measure of angle ∠CAB will be

We know

∠CAB + ∠CAD = ∠DAB

x + x + 1 = 51

        2x = 50

          x = 25

Then the measure of the angle ∠CAB will be

∠CAB = x

∠CAB = 25
