Question

geometry help!!!!!!!!

Answer 1

show work please.

Answer 2

12.

Answer 3

The distance between two points P(a,b) and Q(c,d) is given by
\[d(P,Q)=\sqrt{(c-a)^2+(d-b)^2}=\sqrt{104}\approx10.2\]

The midpoint of the segment determined by the points E(a,b) and C(c,d) is given by
\[P_m=\frac{E+C}{2}=(2,1)\]

Answer 4

Thank You!!!! :D

Answer 5

have you got the other end point @blackleopard?

Answer 6

i think its (-7,-2)... ?

Answer 7

compare the points C and E , how much has the x coordinate changed?
how much has the y coordinate changed?

Answer 8

yeah look likes you got -6 for the change in x
and -2 for the change in y
so applying this change again to E to get D
you got -1-6=-7 for x

and 0-2 =-2 for y

that's right

Answer 9

you might have used a different method

Answer 10

Oh, I misread the question 11, sorry.

Answer 11

so wats the answeR?

Answer 12

With my method the correct answer should be,
\[(-1,0)=\frac{(x,y)+(5,2)}{2}\Rightarrow(-2,0)=(x,y)+(5,2)\Rightarrow(x,y)=(-7,-2)\]where (x,y) are the coordinates of the endpoint they ask for. So the answer for c is (-7,-2) as @UnkleRhaukus wrote.
