For x²+bx+c, to complete the square, you add (half of b)²
b=8 in this case, so you add 4², which is 16
x²+8x+16-16-4
y=(x+4)²-20 is the final form.
Answer:
intersecting lines that have the same slope but different y-intercepts
Step-by-step explanation:
I'm assuming this is from A P E X , right?

Answer:
87°
Step-by-step explanation:
The two marked angles are "vertical angles," so have the same measure. We can't read the number, but suspect it might be 87°. If so, then x° = 87°.
Slope is 4/5
Points are (3,6)
Your first point should be (3,6) then from that point go up 4 and 5 to the right, that should be your second point, then graph.
The answer would be (-5,9)
The formula of a 270° rotation about the origin is (x,y) <span>→ (-y,x).</span>
