Which polynomial is written in descending order? (2 points) select one: a. 9 − 3x + 4x2 b. −3x + 9 + 4x2 c. 4x2 − 3x + 9 d. 4x2 + 9 − 3x

Option C. (4x² -3x + 9)

Step-by-step explanation:

Arranging a polynomial in descending order means to arrange the powers of variables of each term in the descending order.

So in the given options only Option C. is in the descending order.

4x² - 3x + 9

This polynomial has the variable x² with maximum degree of 2 at the starting.

Then second variable 3x with degree of 1 and then constant term 9.

Option C. is the correct option.

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
