Select the expressions that are equivalent to 
–
3(
–
3y–1).


To solve for expressions that are equivalent to \( -3(-3y - 1) \), let's simplify this expression step-by-step:

### Step 1: Apply the distributive property
We distribute the \( -3 \) to each term inside the parentheses:

\[
-3(-3y - 1) = (-3) \cdot (-3y) + (-3) \cdot (-1)
\]

### Step 2: Multiply the terms
- \( (-3) \cdot (-3y) = 9y \)
- \( (-3) \cdot (-1) = 3 \)

So, the simplified expression is:

\[
9y + 3
\]

### Conclusion:
The expression \( -3(-3y - 1) \) simplifies to \( 9y + 3 \). Therefore, any expression equivalent to \( 9y + 3 \) would also be equivalent to the original expression.
