Sure, let's go through the given expression step-by-step to arrive at the answer.

We start with the expression:
[tex]\[ 9 + 4(1)(-1) \][/tex]

Step 1: Evaluate the product inside the expression.
[tex]\[ 4(1)(-1) \][/tex]

Step 2: Multiply 4, 1, and -1.
[tex]\[ 4 \times 1 = 4 \][/tex]
[tex]\[ 4 \times (-1) = -4 \][/tex]

So, the product [tex]\( 4(1)(-1) \)[/tex] simplifies to -4.

[tex]\[ 9 + (-4) \][/tex]

Step 4: Simplify the expression by performing the addition operation.
[tex]\[ 9 + (-4) = 5 \][/tex]
