9. Complete the sentences below with the correct question tags​

Sure! Here is the step-by-step solution to complete the sentences with the correct question tags:

1. Sentence: You have finished your homework, ______?
First, we identify the main clause: "You have finished your homework."
Since the main clause is positive, the question tag is negative. We use the auxiliary verb "haven't" to create the question tag.
Answer: "You have finished your homework, haven't you?"

2. Sentence: She doesn't like coffee, ______?
Again, identify the main clause: "She doesn't like coffee."
The main clause is negative, so the question tag should be positive. We use the auxiliary verb "does" to create the question tag.
Answer: "She doesn't like coffee, does she?"

3. Sentence: They haven't seen the movie, ______?
Main clause: "They haven't seen the movie."
Since the main clause is negative, the question tag should be positive. We use the auxiliary verb "have" to create the question tag.
Answer: "They haven't seen the movie, have they?"

4. Sentence: He won't be coming to the party, ______?
Main clause: "He won't be coming to the party."
Since the main clause is negative, the question tag should be positive. We use the auxiliary verb "will" to create the question tag.
Answer: "He won't be coming to the party, will he?"

5. Sentence: We are going to the concert, ______?
Main clause: "We are going to the concert."
Since the main clause is positive, the question tag is negative. We use the auxiliary verb "aren't" to create the question tag.
Answer: "We are going to the concert, aren't we?"

Remember, these rules can be different depending on the situation or context. However, for the purpose of answering the question, the above solutions should be appropriate.
