Answer:
a) The standard form of is , b).
Step-by-step explanation:
a) The standard form of the complex number is , . If we get that , whose standard form is obtained by algebraic means:
1) Given
2) Distributive and Associative properties.
3) Multiplication/Result.
The standard form of is .
b) The De Moivre's Theorem states that:
Where:
and .
If we know that , then:
The resulting expression is:
Therefore, .
2) All values that satisfy y<1/3-3 are solutions
3) All values that satisfy either equations are solutions
4) There are no solutions
(Edge 2020)
The solution of the system of linear inequalities is All values that satisfy y<1/3-3 are solutions. (option 2)
A relationship between two expressions or values that are not equal to each other is called inequality.
Given is a graph of inequalities, y < 1/3x-1 and y < 1/3-3
The solution of the inequality A is the shaded area below the solid blue line and the solution of the inequality B is the shaded area below the solid red line,
That means all the solutions of inequality B will satisfy the inequality A also.
Hence, The solution of the system of linear inequalities is All values that satisfy y<1/3-3 are solutions. (option 2)

Answer:
relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other.

3x-y+5z=-10
-x+2y+3z=-1
Answer:
x=1, z=-2, y=3
Step-by-step explanation:
Substitution Method
The attached drawing is the apartment using the scale 20 ft to 1 unit from the apartment to the drawing.
As the perimeter lies along the edges of squares and we count 16 sides of squares as we work around the perimeter,
this means that each square is
160 / 16 = 10 ft on a side.
so 10 ft in real life plots to 1 unit on the drawing
If the scale is changed to 20 :1 ,
then the drawing would be exactly the same shape, only each side would have half the original drawing units.
In stead of a 40 ft side being represented by 40 ft / 10 ft/unit = 4 units,
That side would be 40 ft / 20 ft/unit = 2 units
Hence, The attached drawing is the apartment using the scale 20 ft to 1 unit from the apartment to the drawing.
