D) -1.3 x
E) -1.5 x

Question

Quizplus · Accepted Answer

To simplify the expression, we need to combine the like terms. The like terms are the ones with the same variable raised to the same power. So, we have x, -0.4x, and -1.9x as the given terms. Now, the coefficient of x in the simplified expression will be the sum of the coefficients of the like terms, i.e., 
1 - 0.4 - 1.9 = -1.3
Therefore, the simplified expression is -1.3x, which corresponds to choice D.
