What is the sum of the polynomials?

Nadya [2.5K]

For this case we have the following polynomials:

$-x ^ 2 + 9\\-3x ^ 2 - 11x + 4$

Adding the polynomials we have:

$(-x ^ 2 + 9) + (-3x ^ 2 - 11x + 4)$

Rewriting we have:

$x ^ 2 (-1-3) - 11x + (9 + 4)$

Therefore, the result of the sum is:

$-4x ^ 2 - 11x + 13$

Answer:

the sum of the polynomials is:

$-4x ^ 2 - 11x + 13$

Read the following description of a

Annette [7]

Answer:

$\sf a = \boxed{\bf 1} \ n+ \boxed{\bf 3}$

Explanation:

$\sf \underline{rate} \ = \ \sf \dfrac{y_2-y_1}{x_2-x_1} \ = \ \dfrac{rise}{run} \ = \ \dfrac{11-10}{8-7} \ = \ \underline{1}$

<u>Equation</u>:

$\Rightarrow \sf a - a1 = m(n - n1)$

$\Rightarrow \sf a - 10 = 1(n -7)$

$\Rightarrow \sf a = n - 7 + 10$

$\Rightarrow \sf a = n + 3$
