Which expression is equivalent to 2+8x–9?

Answer 1

To simplify the expression \(2 + 8x - 9\), you can combine the constant terms:

1. Combine the constants \(2\) and \(-9\):
\[
2 - 9 = -7
\]

2. Now, the expression can be rewritten as:
\[
8x - 7
\]

Therefore, the equivalent expression to \(2 + 8x - 9\) is:
\[
8x - 7
\]
