Javier writes an integer on a piece of paper. the absolute value of his number is less than 4. which is true of the possible val
Vadim26 [7]

The possible values are less than 4 but greater than -4.

In the given statement is :

Javier writes an integer on a piece of paper. The absolute value of his number is less than 4.

What is Inequality?

Inequality, a statement of an order relationship - greater than, greater than or equal to, less than, or less than or equal to -- between two numbers or algebraic expressions.

Let the integer written by Javier be x

Thus, According to the given situation

=> x > 4 and -x > 4

=> x > 4 and x < -4 (by multiplied -1 on both sides , the inequality reverse)

=> -4 < x< 4

The possible values are less than 4 but greater than -4

What is the missing value<br> Please hurry
telo118 [61]

Answer:

Simplifying

6x + -2y = 30

Solving

6x + -2y = 30

Solving for variable 'x'.

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

Add '2y' to each side of the equation.

6x + -2y + 2y = 30 + 2y

Combine like terms: -2y + 2y = 0

6x + 0 = 30 + 2y

6x = 30 + 2y

Divide each side by '6'.

x = 5 + 0.3333333333y

Simplifying

x = 5 + 0.3333333333y

Factor over complex numbers 2x^4+36x^2+162
Darina [25.2K]

<u>Answer:</u>

Factor over complex numbers of 2 x^{4}+36 x^{2}+162 is 2(x+3 i)^{2}(x-3 i)^{2}

<u>Solution:  </u>

From question given that

2 x^{4}+36 x^{2}+162  → (1)

On substituting x^{2}=y in equation (1),

=2 y^{2}+36 y+162

Taking 2 as a common in above expression,

=2\left(y^{2}+18 y+81\right)

Rewrite the above expression,

=2\left[y^{2}+2(y)(9)+9^{2}\right]

=2(y+9)^{2}  \left[\text { Using }(a+b)^{2}=a^{2}+2 a b+b^{2}\right]

=2\left(x^{2}+9\right)^{2} \left[\text { since } y=x^{2}\right]

\left[\text { Using } a^{2}+b^{2}=(a+i b)(a-i b), \text { where } i=\sqrt{-1}\right]

=2[(x+3 i)(x-3 i)]^{2}

=2(x+3 i)^{2}(x-3 i)^{2}

Hence Factor over complex numbers of 2 x^{4}+36 x^{2}+162 is 2(x+3 i)^{2}(x-3 i)^{2}
