Si al aplicar una homotecia a una figura se obtiene otra figura semejante y de menor tamaño, ubicada entre el centro de homotecia y la figura original, entonces el valor de k es: * –1 < k < 0
k > 1
k < –1
0 < k < 1

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7

step-by-step explanation:

because i took test

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
