Final answer:

The expression simplifies to -3 by combining like terms and constants.

Step-by-step explanation:

The expression 8z + z - 5 - 9z + 2 can be simplified by combining like terms. We can add the coefficients of the z terms together and then combine the constant terms.

To simplify:

  • Combine z terms: 8z + z - 9z = 8z + 1z - 9z = (8 + 1 - 9)z = 0z
  • Combine constant terms: -5 + 2 = -3

Since 0z is equal to 0, we are left with:

-3

So 8z + z - 5 - 9z + 2 simplifies to -3.

You have to use PEMDAS to answer. So I believe that it is -3. Explanation the 8Z +Z is 9Z. Then it cancels out because of the -9z. So now you must and be -5+2 which is three
