Suppose you have ab on a coordinate plane located at a(-3,-4) and b(5,-4)
under a dilation centered at (9,0), ab becomes a'b' with coordinates a' (6,-1)
and b'(8,-1). what is the scale factor for this dilation?
what’s the answer

its b

step-by-step explanation:

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
