add the equal vectors of p, q, and r shown below.

OpenStudy (anonymous):

OpenStudy (freckles):

well we could find the vectors in standard form then just use that <a,b>+<c,d>+<e,f> =<a+c+e,b+d+f>

OpenStudy (anonymous):

okay how do i do that? can you walk me through it?

OpenStudy (freckles):

for example look at the terminal point and being point of vector p terminal point is (1,5) and begin point is (2,2) so vector p is <1-2,5-2>=<-1,3>

OpenStudy (freckles):

you can do the same for the other vectors

OpenStudy (anonymous):

okay let me try

OpenStudy (anonymous):

okay so q is (5,1),(1,4)

OpenStudy (anonymous):

and r is (7,1),(6,4)

OpenStudy (freckles):

agree with your r terminal point and begin point but something weird happened with your q

OpenStudy (anonymous):

the answer will be (-3,9)

OpenStudy (freckles):

lol and you know what this problem is way easier than I thought I completely missed the equal word

OpenStudy (freckles):

you already found (I already found a vector in standrad form) you have 3 equal vectors you can do 3(vector p)

OpenStudy (anonymous):

(4,1) and (3,4)

OpenStudy (freckles):

and yes that is right

OpenStudy (freckles):

vector p is <1-2,5-2>=<-1,3> vector q is <3-4,4-1>=<-1,3> vector r is <6-7,4-1>=<-1,3> to find the vector in standard form you just do terminal minus being point anyways yes you can either add all those up or you can just do 3<-1,3>

OpenStudy (anonymous):

okay that makes sense. i see what you did.

OpenStudy (freckles):

cool stuff
