8 is the only factor of 8x.

1 answer

In the given equation \( 8x - 3y = 2x + 9y \), let's analyze the statements:

  1. 8, −3, 2, and 9 are coefficients.

  2. 8, negative 3, 2, and 9 are coefficients.
    Both of these statements are indeed correct. Coefficients are the numbers multiplying the variables, so in this case:

    • 8 is the coefficient of \( x \) in \( 8x \).
    • -3 is the coefficient of \( y \) in \( -3y \).
    • 2 is the coefficient of \( x \) in \( 2x \).
    • 9 is the coefficient of \( y \) in \( 9y \).
  3. There are four variables.
    This statement is incorrect. There are only two variables: \( x \) and \( y \).

  4. 8, −3, 2, and 9 are constants.
    This statement is incorrect. Constants are values that do not change and are not multiplied by a variable.

  5. 8 is the only factor of 8x.
    This statement is misleading. While 8 is a factor, \( x \) itself is part of the expression \( 8x \), making it a product, not simply a factor.

Based on the analysis, the correct responses are the first two statements about coefficients:

8, −3, 2, and 9 are coefficients.
8, negative 3, 2, and 9 are coefficients.
