Answer:
Step by step below
Step-by-step explanation:
center of dilation: W
Similarity statement:
wx/wx' = wz/wz' = xy/x'y' = yz/y'z' = 5/3
∠w = ∠w=90°, ∠x = ∠x'=90°, ∠y = ∠y'=90°, ∠z = ∠z'=90°
square wx'y'z' ~ wxyz
Answer:
-6x + 8(-x+6) = 6
Step-by-step explanation:
x+y = 6 => y = 6-x ..............(1)
Substitute y (1) in
-6x+8y = 6 .......................(2)
to get
-6x + 8(6-x) = 6
or equivalently
-6x + 8(-x+6) = 6
