question 1 of 40
when the expression $-3x^5 + 6x^2 - 9x^3 - x$ is written with terms in descending order (from highest to lowest), which list represents the coefficients of the term?

a. -3, -9, 6, -1

b. -3, 6, -9, -1

c. 1, 6, -9, -3

d. 6, -9, -3, -1

Explanation:

Step1: Identify exponents of each term

Original expression: $-3x^5 + 6x^2 - 9x^3 - x$. Exponents: $5, 2, 3, 1$.

Step2: Order terms by descending exponents

Order of exponents: $5 > 3 > 2 > 1$. Terms become: $-3x^5, -9x^3, 6x^2, -x$.

Step3: Extract coefficients

Coefficients: $-3, -9, 6, -1$.

Answer:

A. -3,-9,6,-1
