Answer:
B and D
Step-by-step explanation:
For a linear equation, the degree is 1.
For y=x² , the degree is 2, so it is not linear.
For y=2x, the degree is 1, so it is linear.
For y=4/x----->xy=4, the degree is 2, so it is not linear.
For y=x/4, we have 4y=x, the degree is still 1, this is also linear.
The correct options are B and D.
Answer:
Step-by-step explanation: If the clock is total 360 degrees and only 20 minutes passed out of 24 hours it would be an acute angle because it is much less than 90 degrees.
