-1, because
if you factor out -1 from a-b you get -1(-a+b). when you reduce, -a+b = b-a so those cancel out and you are left with -1
I think its BA.
yes it is
ab = 8-cDivide both sides by ba = (8-c)/b
BS
A - B = B - AThis statement is very difficult to prove.Mainly because it's not true . . . unless 'A' happens to equal 'B'.
(a/b)'= (ba'-ab')/(b²)
If these are vectors, then ba = - ab
NB, Nb
The GCF is ab
[(aa + bb) + (ab+ba)(aa+bb)*(ab+ba)]*[a + (ab+ba)(aa+bb)*b]
Yes.
Line BA
Yes, provided it is the ray. If AB is a vector then the answer is no.
I think its BA.
AB and BA.
yes it is
Yes.
