To find the value of the expression \( y^2 + 10y - 8 \) when \( y = 9 \), we can substitute the value of \( y \) into the expression.
1. Substitute \( y = 9 \):
\[
9^2 + 10(9) - 8
\]
2. Calculate \( 9^2 \):
\[
9^2 = 81
\]
3. Calculate \( 10(9) \):
\[
10(9) = 90
\]
4. Substitute these values back into the expression:
\[
81 + 90 - 8
\]
5. Now, perform the additions and subtractions:
\[
81 + 90 = 171
\]
\[
171 - 8 = 163
\]
Thus, the value of the expression \( y^2 + 10y - 8 \) when \( y = 9 \) is **163**.
