Answer:
86,000
Step-by-step explanation:
Find the thousands place value (will be bolded and underlined):
8<u>5</u>,634
Look to the place value directly to the right of what you are looking for. In this case, it is a 6. If the number is 5 or greater round up, if 4 or less, round down:
85,634 rounded to the nearest thousand is 86,000.

Answer:
-14 - 11i
Step-by-step explanation:
You may be learning about the imaginary number, i. Even though i is actually the squareroot of -1, when you are doing algebra with it, it acts just like a variable does. The special thing to remember about i is that i^2 is -1. But we don't even need that right now for this problem.
(-14 + 3i) - (14i)
= -14 + 3i - 14i
Combine the i's
= -14 - 11i
That's it. The -14 is the a, and the -11 is the b in a+bi.
If necessary to fill in a computer answer that is already formatted with a plus, like:
_ + _i
then use -14 for a and -11 for b.
