Simplify the expression $-9(y+8)+9$ .

STEP 1

Assumptions1. We are given the expression $-9(y+8)+9$ . . We need to simplify this expression.

STEP 2

We can simplify this expression by first distributing the $-9$ to both $y$ and $8$ inside the parentheses. This is done according to the distributive property of multiplication over addition, which states that $a(b+c) = ab + ac$ .
$-9(y+8) = -9y + -98$

STEP 3

Now, plug in the values and calculate the result of the multiplication.
$-9y + -98 = -9y -72$

STEP 4

Now, we can add the $9$ to the result of the multiplication.
$-9y -72 +9$

STEP 5

Finally, we simplify the addition.
$-9y -72 +9 = -9y -63$ So, the simplified form of the given expression is $-9y -63$ .
