Answer:
A
Step-by-step explanation:
You can solve with the formula for cuadratic equations:
x=−b±√b2−4ac
2a
Answer:
D
Step-by-step explanation:
The figures are the same just flipped. We can tell AD=NM ON=AB, BC=OP. Thus DC =MP
DC has the length of 6 and because MP is congruent to DC it also has 6.
Answer:
HUH? What do you mean about that?
Slope is

if we plug in your coordinates we get:

Therefore, the slope of (0,1) and (2,7) is 3.
