What are the x- and y-coordinates of point p on the directed line segment from a to b such that p is the length of the line segment from a to b? * = ( mm – x1) + x4 v = ( m m m ]lve - va) + 1 o (2,-1) o (4, -3) o (-1,2) o (3,-2)

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

regards,  

mrb
