Answer:
-9a + b
Step-by-step explanation:
For this problem, let us factor out the variable a from the terms containing the variable, and apply addition and the distributive property to simplify the terms.
-5a - 4a + b
= a ( -5 + -4 ) + b
= a ( -9 ) + b
= -9a + b
Hence, the simplified expression for -5a - 4a + b is -9a + b.
