Domain are x values (independent variable);

Speed would be independent so what speeds can be used ? -30 mph, 30 mph, 1000 mph?

Can a car go 0 mph?

What is realistic?

I would say 0 greater or equal to x greater than whatever you think is beyond the max that a car can go.

Examples of geometric transformations can be found throughout the real world. Think about some places where you might use or see
lina2011 [118]

Answer:

We know that there are four types of geometric transformations namely translation, reflection, rotation and dilation.

1. Translation: It is a rigid transformation that moves the objects in any direction. Few examples of translation we see in real life are:

A. When we move furniture in the house from one place to another.

B. The position of a car on the road is an example of translation.

C. When we changes the places of pieces on the chessboard.

2. Reflection: is a rigid transformation that flips the object. It can be easily observed in real life in the following ways:

A. The reflection of light from any object is the most easily viewed example of reflection.

B. Looking at yourself in the mirror is because of reflection.

C. When we can see our faces through clear water is also because of reflection.

3. Rotation: It is a rigid transformation that turns the object to a certain degree. The few examples of rotation are:

A. Opening of the door to a certain angle.

B. The spinning of Earth, Sun and other planets.

C. The moving of the hands of the clock is an example of rotation.

4. Dilation: It is a rigid transformation that changes the shape of the object. It's few examples are:

A. Enlarging the image on a computer.

B. Blowing air in the balloon to make it large.

C. Miniature version of buildings that are in proportion to the actual size of the buildings.

Hence, the transformations can be easily observed in real life.

Answer:

<h2>2 c. = 1 pt.</h2><h2>2 pt. = 1/4 qt.</h2><h2>1 gal. = 4 qt.</h2><h2>4 qt = 1 gal.</h2>

Step-by-step explanation:

\boxed{1gal.=4qt.=8pt.=16c}\\\\1pt.=2c.\Rightarrow 2c.=1pt.\\\\1qt.=8pt.\to1pt.=\dfrac{1}{8}qt.\Rightarrow2pt.=2\cdot\dfrac{1}{8}qt.=\dfrac{1}{4}qt.\\\\1gal=4qt.\Rightarrow4qt.=1gal.

(|5 - 3x | - 1) - ( 1 - 3x ) = 0
Basile [38]

(| 5 - 3x | - 1) - (1 - 3x) = 0

|5 - 3x| - 1 - 1 + 3x = 0

|5 - 3x| - 2 + 3x = 0

1) (5 - 3x) - 2 + 3x = 0, if 5 - 3x >= 0

3 = 0. has no solutions

2) -(5 - 3x) - 2 + 3x = 0, if 5 - 3x < 0

-5 + 3x - 2 + 3x = 0

6x = 7

x = 7/6

5 - 3x < 0

-3x < -5

x > 5/3.

has no solutions

PLEASE HURRY WILL GIVE BRAINLIEST A truck can be rented from Company A for $90 a day plus $0.30 per mile. Company B charges $70
rjkz [21]

Answer:

  40 miles a day

Step-by-step explanation:

The difference in fixed charge is $20; the difference in mileage charge is $0.50 per mile. So it will take $20/$0.50 = 40 miles for the extra mileage cost to eat up the savings in fixed cost. At that mileage, both companies will charge the same amount:

  A: 90 + 0.30·40 = 102

  B: 70 + 0.80·40 = 102
