99,999,999 + (-4) is basically 99,999,999 - 4

99,999,999 - 4 = 99,999,995

99999999+-4 is actually 99999999-4 so remember that a positive plus a negative is actually subtracting a positive so 99999999+(-4) is <span>99999995.</span>

What are complex integers ?

Brut [27]

Answer:

In mathematics, a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a symbol, called the imaginary unit, that satisfies the equation i² = −1. Because no real number satisfies this equation, i was called an imaginary number by René Descartes.

Step-by-step explanation:

Complex Integer

(or Gaussian integer), a number of the form a + bi, where a and b are integers. An example is 4 – 7i. Geometrically, complex integers are represented by the points of the complex plane that have integral coordinates.

Complex integers were introduced by K. Gauss in 1831 in his investigation of the theory of biquadratic residues. The advances made in such areas of number theory as the theory of higher-degree residues and Fermat’s theorem through the use of complex integers helped clarify the role of complex numbers in mathematics. The further development of the theory of complex integers led to the creation of the theory of algebraic integers.

The arithmetic of complex integers is similar to that of integers. The sum, difference, and product of complex integers are complex integers; in other words, the complex integers form a ring.

The value of linear Equations and Inequalities x is $5.16\geq x > -1$

linear Equations and Inequalities:

A linear equation is an equation of a straight line where the power of the variable is 1. It is expressed as ax + b = 0, where x is the variable and a and b are integers. Inequality is a statement of comparison between two expressions. Linear Inequations are two expressions where their values are compared by the inequality symbols such as <, >, ≤ or ≥. One variable linear equations and Inequations have only one solution or one root. Examples of one variable linear equations and inequations are x = 4, 2a + 3 = 9, 3x < 2 , 4y - 5 > 6. etc

Method :

For solving a linear equation or inequality having only one variable, the following steps are followed, while still balancing the equation.

Add or subtract like terms

Isolate the variable

Transpose or eliminate the terms

Verify the answer.

Solution :

$12x - 3\leq 59\\12x\leq 59+3\\12x\leq 62\\x\leq \frac{62}{12} \\x\leq \frac{31}{6} \\x\leq 5.16\\\\\\6x +4 > -2\\6x > -2-4\\6x > -6\\x > -1\\\\5.16\geq x > -1$
