The answers are D, D, 93, A, A.
Hello,
y=x²-x-2=x²-2*1/2*x+1/4-2-1/4=(x-1/2)²-9/4
1. Vertex=(1/2,-9/4)
2. if x=0 then y=0²-0-2=-2
3.The roots:
x²-x-2=0
==>(x-1/2)²-9/4=0
==>(x-1/2-3/2)(x-1/2+3/2)=0
==>(x-2)(x+1)=0
x=2 or x=-1
4. axe of symmetry: x=1/2
Lets get the negative reciprocal of the slope so we get

Now the equation that is perpendicular is

Lets solve for b by plugging in the point (x,y)=(6,1)

Now plug that into the equation. So the equation of the line that is perpendicular and
passes through the point (6, 1) is
4/9 > 33/100 > 1/7 > 2/25
Turn the decimals to fractions.
0.33 <span>· 100 = 33/100
0.08 = 2/25</span>
Answer:
52
Step-by-step explanation:
(2x3 = 6
4x5 = 20)
(6+20) = (26)
(26)2 = 52
