Answer:
Option B, z = 2
Step-by-step explanation:
<u>Step 1: Factor</u>
z^2 - 4z + 4 = 0
<em>(z - 2)(z - 2) = 0</em>
<em />
<u>Step 2: Solve for z</u>
z - 2 + 2 = 0 + 2 and z - 2 + 2 = 0 + 2
z = 2 and z = 2
<em>Double root at z = 2</em>
<em />
Answer: Option B, z = 2
If the line is parallel they will have the same slope
Answer:
(0,-1)

Find value
1quaqrter=25 cents
2nickles=2*5=10 cents
1 dime=10 cents
3 pennies=3 cents
total is
25+10+10+3=48
48 out of 100 cents
48/100=48%
the answer is 48%
Let's take a look at D:
<span>D) y = (x-1)^2 - 16 Compare this to
y = (x-h)^2 + k This is the std. equation of a parabola in vertex form.
You can see, by comparison, that h=1 and k= -16; these are the coordinates of the vertex, clearly shown in the diagram.
Since the coefficient of (x-h)^2 is +1, the graph opens upward (which the given graph confirms), and is neither compressed nor stretched vertically.</span>
