Match the inequality to the graph of its solution. (2 points)
# c + 7 < 3
ac - 3 > 1
#e-7<3
For the inequality c + 7 < 3, the solution is c < -4. The graph of its solution would be a number line with an open circle at -4 and an arrow pointing to the left.
For the inequality ac - 3 > 1, the solution is a > 2. The graph of its solution would be a number line with an open circle at 2 and an arrow pointing to the right.
For the inequality e-7<3, the solution is e < 10. The graph of its solution would be a number line with an open circle at 10 and an arrow pointing to the left.
Solve.
2.7 <= b + 5
(1 point)
b >= 7.7
b >= - 2.3
O b <= 2.3
b <= - 7.7
To solve the inequality 2.7 <= b + 5, we can subtract 5 from both sides to isolate the variable:
2.7 - 5 <= b + 5 - 5
-2.3 <= b
Therefore, the solution is b >= -2.3.
You have a gift card for your favorite clothing store for the amount of $60. You have found a shirt you want to buy that costs $15. If you don't want to spend more than the amount of the gift card, which of the following inequalities could be used to determine the amount you have left to spend?
(1 point)
Ox r + 15 >= 60
Ox x - 15 >= 60
x - 15 <= 60
0x + 15 < 60

Why do writers add multimedia to an informational text? (1 point)
Oto help the reader comprehend the facts, comparisons, or details in the writing
O to hide details from the reader that are boring, nonessential, or irrelevant
O to show the reader why a topic was chosen
Oto make the organizational strategy more clear
The correct answer is: to help the reader comprehend the facts, comparisons, or details in the writing.
By adding multimedia such as images, videos, or interactive elements, writers can provide visual or auditory aids that enhance the reader's understanding and engagement with the information being presented. Multimedia can help clarify complex concepts, provide real-life examples, or support data and evidence mentioned in the text. Overall, it serves as a tool to enhance comprehension and make the information more accessible and engaging for the reader.
What can a writer do to connect a photo to the text? (1 point)
O Put information about the photo in a graphic organizer.
O Provide a video about the same topic.
O Add additional photos to it.
Include a caption describing the image.
The correct answer is: Include a caption describing the image.
By including a caption, the writer can provide contextual information about the photo, explaining its relevance to the text. The caption can describe the subject matter of the photo, provide additional details, or highlight key points related to the text. This helps to establish a clear connection between the photo and the accompanying text, providing the reader with a better understanding of how the photo supports or relates to the information being presented.
Which observation most likely indicates that only a chemical change has taken place? (1 point)
The shape changes.
The change cannot be reversed.
OA reaction occurs
States of matter changes.
The correct answer is: A reaction occurs.
When a reaction occurs, it typically indicates that a chemical change has taken place. Chemical changes involve the rearrangement of atoms and the formation of new substances with different chemical properties. These changes often cannot be easily reversed. Therefore, the observation of a reaction occurring is the most likely indication that only a chemical change has taken place.

1 and 4
Change

(1 point)
2 and 4
Based on the table provided, the physical changes are indicated by the changes shown in rows 2 and 4.
Change 2 states that a gas, sound, or light is produced. The production of a gas, sound, or light is a common indication of a chemical change, not a physical change.
Change 3 indicates a temperature change. Temperature changes can occur in both physical and chemical changes. However, because it is not specified whether this temperature change is due to a chemical reaction or a change in state, it cannot be definitively categorized as a physical change.
Change 4 states if the substance reacts with another substance. This is indicative of a chemical change, not a physical change. The ability to react with another substance and form new substances is a key characteristic of chemical changes.
Therefore, the physical changes shown in the table are indicated by changes 2 and 4.
Why is it a physical change to freeze water? (1 point)
The new and original substances are different
OA temperature change occurs.
Only a phase change occurs.
Heat is released during the process.
The correct answer is: Only a phase change occurs.
Freezing water involves a physical change because it is a phase change from a liquid to a solid state. In this process, the water molecules rearrange themselves and form a crystalline structure without any change in the chemical composition of the water molecules. The new substance, ice, has the same chemical composition as the original substance, water. Therefore, the freezing of water is considered a physical change rather than a chemical change.
Which option is an example of a chemical change?
O stretching a rubber band
O burning wood
O folding paper
Ochopping vegetables
The example of a chemical change is burning wood.
Burning wood involves a chemical reaction known as combustion. When wood is burned, it undergoes a chemical reaction with oxygen in the air, resulting in the release of heat, light, and the production of new substances such as carbon dioxide and water vapor. This process changes the chemical composition of the wood, making it an example of a chemical change.
The U.S. Founders agreed with many of the Roman Republic's ideas about the responsibilities of citizens.
List one of the civic virtues that the Roman Republic and the United States Founders valued in citizens:
One civic virtue that both the Roman Republic and the United States Founders valued in citizens is "civic duty."
Civic duty refers to the moral and social responsibility that citizens have towards their community and country. It includes fulfilling one's obligations as a citizen, such as voting, paying taxes, serving on juries, and participating in civic activities. Both the Roman Republic and the United States Founders believed that citizens should actively participate in the democratic process and contribute to the well-being and success of their societies through their civic duty.
To determine the amount you have left to spend, we can subtract the cost of the shirt from the amount of the gift card.
Let x represent the amount left to spend.
So, the equation would be:
x - 15 <= 60
Therefore, the correct inequality is x - 15 <= 60.
