Final answer:
To find the equivalent expression for -1/4(-8x+12y), distribute -1/4 to both terms inside the parentheses to get (2x - 3y), which corresponds to answer option a).
Step-by-step explanation:
To expand and write an equivalent expression for -1/4(-8x+12y), we distribute -1/4 to both terms inside the parentheses:
- Multiply -1/4 by -8x, which gives 2x.
- Multiply -1/4 by 12y, which gives -3y.
Combine the results to get the equivalent expression: (2x - 3y).
Therefore, the correct answer is option a) (2x - 3y).
