The graph which correctly shows the point A as the sum of the complex numbers z₁ and z₂ is graph number 4.

<h3>What is complex number?</h3>

A complex number is the combination of real and imaginary number. In a complex number, real part and imaginary part of the number are written together. For example,

a+b<em>i</em>

Here, (a) is the real part while (b) is the imaginary part.

To add the two complex number on the graph, the addition as transition method is used.

In this one complex number is translated to the tip of the other graph. The resultant of addition is equal to the distance between them.

On the graph 4, the transition method of addition is applied.Thus, the graph which correctly shows the point A as the sum of the complex numbers z₁ and z₂ is graph number 4.

Carla and Benicio work in a men's clothing store. They earn commission from each suit and each pair of shows they sell. For sell
qwelly [4]

Answer:

The salespeople earn for the sale of a suit = $13.

The salespeople earn for the sale of a pair of shoes = $8.

Step-by-step explanation:

Let x be the commission for each suit and y be commission for each pair of shoes.

We have been given that for selling 3 suits and one pair of shoes, Carla has earned $47 in commission. We can represent this information as:

3x+y=47...(1)

We are also told that for selling 7 suits and 2 pairs of shoes, Benicio has earned $107 in commission. We can represent this information as:

7x+2y=107...(2)

We will use substitution method to solve our system of linear equations. From equation (1) we will get,

y=47-3x

Substituting this value in equation (2) we will get,

7x+2(47-3x)=107

7x+94-6x=107

Upon combining like terms we will get,

7x-6x=107-94

x=13

Therefore, the salespeople earn $13 for the sale of a suit.

Let us substitute x=13 in equation (1).

3*13+y=47

39+y=47

y=47-39

y=8

Therefore, the salespeople earn $8 for the sale of a pair of shoes.
