2. What is the domain of y = 7x – 4 when the range is 10?

At a local bowling alley, the company charges $1 an hour to rent their shoes.

4. Lisa stayed to talk to her friends for about 5 minutes after school. Then she started to walk home. Halfway home she realized that she had forgotten her math book, so she ran back to school in half the time that she had already spent walking. Lisa took about 2 minutes to get her book and then walked home. She got home approximately 35 minutes after school was over. Which graph best represents this scenario? Time (min.) Distance from Home (mi. ) Time (min.) A B C Distance from Home (mi. )

Danny has a gift card with $300 to game stop. He will buy $50 games with it.

12. Gina did a research project on how age affects sleep patterns. She concluded that as people age, they sleep fewer hours until a point in adulthood when the number of hours remains constant. Gina also found that after the age of 70 the amount of time spent sleeping increases slightly. Which graph best shows Gina’s results? A B CD
