Answer:

  x < -3 or x > 4

Step-by-step explanation:

The product of the factors is 4th-degree, and the leading coefficient is 1 (positive).

The factors tell you the following about the zeros:

  x = -3 . . . sign change from + to -

  x = -1 . . . graph touches, but no sign change. - on either side of x=-1

  x = 4 . . . sign change from - to +

__

The function will be positive for x < -3 and for x > +4.

_____

<em>Additional comments</em>

The value of the function is zero when any of its factors is zero. The value of a factor changes sign when the value of x changes from one side of the 0 to the other. For example, here, we have x+1 as a factor, so x=-1 is a zero. When x = -0.9, the factor is positive (-0.9 +1 = 0.1). When x = -1.1, the factor is negative (-1.1 +1 = -0.1). If this factor were to the first power, it would cause the value of the function to change sign at x=-1.

However, the factor (x+1) has an even power: (x+1)^2. That means when the factor is negative, its square is positive, and when the factor is positive, its square is positive. In short, the factor (x+1)^2 causes the function to be zero at x=-1, but does not make the function change sign there.

The product of all of these factors will result in a polynomial with x^4 as the highest-degree term. That means the function is of even degree. The leading coefficient is 1, so is positive, and the function will generally have a U-shape. The left-most (odd-degree) zero will be where the function changes sign from positive to negative. The right-most (odd-degree) zero will be where the function changes sign from negative to positive. Those zeros are x=-3 and x=+4, respectively. There are no places between these where the function changes sign, so these zeros are the ends of the regions where the function is positive (>0).

Three added to eight times a number is the same as three times the value of two times the number -1
emmainna [20.7K]

Answer:

The number x is -3

Therefore x=-3

Step-by-step explanation:

Given problem is "Three added to eight times a number is the same as three times the value of two times the number -1"

Let x be the number

It can be written as

3+8\times x=3(2\times x-1)

3+8x=3(2x-1)  ( applying the distributive property )

3+8x=3(2x)+3(-1)

3+8x=6x-3

subtracting (6x-3) on both sides we get

3+8x-(6x-3)=6x-3-(6x-3)

3+8x-6x+3=6x-3-6x+3

6+2x=0 ( ading the like terms )

2x=-6

x=-\frac{6}{2}

Therefore x=-3

The number x is -3

Anna11 [10]
No this is not a valid reference because those were 20 random families, if he does another test the next twenty families 50% of them could attend the party. Too much chance to be valid.
