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.

10^2 + 5^2 = Diagonal length. so, 100 + 25 = 125 diagonal length
Step-by-step explanation:
6) (2x+1) + (x+15) + x = 180
x = 41
So (2x+1) = 83 is the largest one
7) a) x + x+2 + 38 = 180
x=70
b) m<70
c) m<72
8) 9x = 180
x = 20
X =20
H= 40
E = 80
Answer:
66
Step-by-step explanation:
mean = the sum of the value / the number of the value
when we calculate the some must be 385 so the sum of the given value gives 319 so to reach the average 77 she must score 66
Answer:
The slope is 2 and the y-intercept is -6
Step-by-step explanation:
we know that
The equation of the line in slope intercept form is equal to

where
m is unit rate or the slope of the linear equation
b is the y-intercept or initial value (value of y when the value of x is equal to zero)
In this problem we have

therefore
the slope is equal to

and
