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 function that could represent the value of a rare coin that increases over time is; y = ²/₃x + 2
<h3>How to create linear equations?</h3>
We want to find which of the equations below could represent the value of a rare coin that increases over time
y = -³/₂x + 1
y = -²/₃x - 7y
y = ²/₃x + 2
y = ³/₂x - 6
Now, the general form of a linear equation in slope intercept form is;
y = mx + c
where;
m is slope
c is y-intercept
Now, for the equation to be increasing over time, it means the slope must be positive and the y-intercept must also be positive.
Looking at the given options, the only one where slope and y-intercept is positive is y = ²/₃x + 2
