Answer:
y=-2/3x+6
Step-by-step explanation:
Graph it
It would have to be an obtuse triangle
Answer:
Trapezoid
Step-by-step explanation:
The two sloped opposite sides are congruent. The two uncongruent opposite sides are parallel. There are no right angles. You can do this by finding the distance and slopes of the lines.
Not triangle because has four vertices.
Answer:
Area is about 1520.53
Step-by-step explanation:
A = 
A ≈ 1520.53
Since they are the conjugates of each (9-a and 9+a are conjugates, or with any number replacing 9) , we multiply it by (9+i)/(9+i) to get (9+i)^2/(9-i^2)=(81+2i+i^2)/(9-(-1))=(81-1+2i)/(10)=80/10+2i/10=8+i/5. Conjugates work because they make i into i^2 (-1) without any of the sneaky i's in the middle!
