Final answer:
In the expression 4r + 9 - y(6x + 7), the "6" is a coefficient, the "9" is a constant, and the "y" is a factor.
Step-by-step explanation:
In the expression 4r + 9 - y(6x + 7), the following statements are true:
- The "6" in the third term is a coefficient.
- The "9" in the second term is a constant.
- The "y" in the third term is a factor.
The "x" in the first term is not an exponent and the "4" in the first term is not a constant. The "7" in the third term is also not a coefficient.
