The value of the expression (x - 9 ) is equal to:

Options

  1. A- x
  2. B- x
  3. Cx
  4. Dx

Correct answer

C. x

Step-by-step solution

(x - 9 ) = - (9 - x) - (9 - x) = - (4(2 ) + - x) Using the periodic property (2n + ) = for integer n : - (4(2 ) + - x) = - ( - x) Since ( - ) = - : - ( - x) = -(- x) = x
