Please help me with this math!
wel

Answer:

Please check the explanation.

Step-by-step explanation:

Given the polynomial function

f\left(x\right)\:=x^3+2x^2-16x-32

Let us determine the factors by solving

\:\left0\right\:=x^3+2x^2-16x-32\:

\left(x+2\right)\left(x+4\right)\left(x-4\right)=0

Using the zero factor principle:

if  ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0\:\left(\mathrm{or\:both}\:a=0\:\mathrm{and}\:b=0\right)

x+2=0\quad \mathrm{or}\quad \:x+4=0\quad \mathrm{or}\quad \:x-4=0

Thus, (x+2) (x+4) and (x-4) are the factors of the polynomial function.

Therefore,

YES

  • (x+2)
  • (x+4)
  • (x-4)

And (x-2) (x+6) are not the factors of the polynomial function.

Therefore,

YES

  • (x-2)
  • (x+6)

Select the relations that are functions.
liraira [26]

Answer:

option A, C  and D

Step-by-step explanation:

Each relation is a function if each input has only one output

{a, 1), (6, 1), (C, 1)

This relation is a function because each input has only one output

{a, a),(a, b),(a, c)}

This relation is not a function because input 'a' has only three output

{(1, a), (2, a),(3, a)}

This relation is a function because each input has only one output

{a, a), (b, b), (C, c)}

This relation is a function because each input has only one output

6)<br> (6x + 1)<br> 49°<br> find x
Rufina [12.5K]

Answer:

X=8

Step-by-step explanation:

Simplifying

6x + 1 = 49

Reorder the terms:

1 + 6x = 49

Solving

1 + 6x = 49

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-1' to each side of the equation.

1 + -1 + 6x = 49 + -1

Combine like terms: 1 + -1 = 0

0 + 6x = 49 + -1

6x = 49 + -1

Combine like terms: 49 + -1 = 48

6x = 48

Divide each side by '6'.

x = 8

Simplifying

x = 8
