Step-by-step explanation:

Let the first integer be x

hence the consecutive integer is x +1

according to the give condition

x + 6(x + 1) = -29

x + 6x + 6 = -29

7x = -29 -6

7 x = -35

x = -35/7

x = -5

x + 1 = -5 + 1 = -4

Tomtit [17]

The key features of polynomials are the vertex, axis of symmetry, x and y intercepts.

 

<span>1.    </span>The degree will help you find the end behavior.

<span>2.     </span>The vertex shows you where it changes concavity.

<span>3.     </span>X and y intercepts give you a couple of points of reference.

<span>4.     </span>Axis of symmetry is only applicable to even degree polynomials.

 

I am hoping that these answers have satisfied your queries and it will be able to help you in your endeavors, and if you would like, feel free to ask another question.
