Question Evaluate \( 2 x+9 y-9 \), when \( x=6 \) and \( y=6 \).

First, let's plug in the values of \( x \) and \( y \) into the expression \( 2x + 9y - 9 \). So, \( 2(6) + 9(6) - 9 \) becomes \( 12 + 54 - 9 \). Now, adding those numbers gives us \( 12 + 54 = 66 \), and subtracting 9 results in \( 66 - 9 = 57 \). Thus, the evaluated expression is \( 57 \).
