Abs(x-y) is the distance between x and y
So it's the distance between any point and 1+i that must be equal to 3, so it's a circle centered on 1+i point
"≠" is not equals.
Inequalities don't equal anything.
The question contains two equations:5x - 6y = 15 5x + y = 2 There are no inequalities in the question.
You cannot, since "x equals 0" and "y equals 0" are NOT inequalities!If x and y are counts of things, or measures (such as length) which must be positive then the reason for such constraints should be obvious.
An expression, or, more pedantically, inequalities.
I would say that you would need to demonstrate that you understand that i is a number which when squared equals -1. Also demonstrate how complex numbers can be represented graphically, both as rectangular coordinates an polar coordinates. Another thing would be an understanding of Euler's relationship: e^(i*Θ) = cos(Θ) + i*sin(Θ). Note that Θ must be in radians for this to work.
You infer that the value of x, which satisfies the equations or inequalities, is zero!
16 - 8y = 4xIt is a straight line equation. Graphically, the line two intercept points are:(0, 2) and (4,0)
None. Properties of inequalities are not that relevant when solving equalities.
it includes i, which equals to negative one
It has two complex roots.
