Answer:
-400i
General Formulas and Concepts:
<u>Algebra II</u>
Step-by-step explanation:
<u>Step 1: Define</u>
z = -400i - 44.5
<u>Step 2: Identify</u>
Treat imaginary <em>i</em> as a variable. The imaginary part of z would be the entire term of <em>i</em>. Therefore, our answer is -400i

Answer:
{-1, 5} (two real solutions).
Step-by-step explanation:
On the left side we want x^2, not x?
We need to rewrite x? = 4x - 5 in standard form, that is, as a quadratic with x terms in decreasing powers of x:
x^2 - 4x + 5 = 0
This factors easily to (x - 5)(x + 1) = 0.
We let each factor equal zero (0) separately and solve for x:
{-1, 5} (two real solutions).
