can you help me to find an equivalant expression without parentheses
-(y-25)
-y + 25
A negative sign outside of parenthesis is telling you to multiply by -1 which makes positive numbers negative and negative numbers positive. So -y+25
To find an equivalent expression without parentheses for the expression -(y-25), you can apply the distributive property.
The distributive property states that for any numbers a, b, and c:
a * (b + c) = a * b + a * c
In this case, -(y-25) can be rewritten using the distributive property as:
-1 * (y - 25)
Applying the distributive property, we can distribute the -1 to both terms inside the parentheses:
-1 * y + (-1) * (-25)
Simplifying further, we have:
-y + 25
Therefore, an equivalent expression without parentheses for -(y-25) is -y + 25.
