Question

Evaluate -a -8b when a=9 and b=3 Help please i need it quick

Answer 1

Start with -a -8b.

Replace a by 9 and b by 3: -(9)-8(3)

Order of operations rules require that we mult. before adding or subtracting.

Therefore, we obtain -9 - 24.

Combining these two terms results in the desired value: -33.
