Which of the following shows the polynomial below written in descending order? 5x3 – x + 9x7 + 4 + 3x11

Step-by-step explanation:

To write a polynomial in descending order, we arrange the terms by their exponents.

The largest exponent we have is 11; this makes the first term in the order .

The next largest exponent we have is 7; this makes the second term in the order 9x⁷.

The next largest exponent we have is 3; this makes the third term in the order 5x³.

The next largest exponent we have is 1; this makes the fourth term in the order -x¹, which is the same as -x.

The last term will be 4.

This makes the order 3x¹¹ + 9x⁷ + 5x³ - x + 4

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
