Answer:

z= 5-2i

Step-by-step explanation:

Start replacing!

(x+iy) + 4i (x-iy) = -3+18i \\ x+iy +4ix -4i^2 y = -3 + 18i \\\\x + i (4x+y) +4y = -3 + 18i\\x+4y + (4x+y) i = -3 + 18i

Now two complex numbers are equal if both the real and imaginary parts are equal, which gives you the system of equation \left \{x+4y=-3} \atop {4x+y=18} \right.

Pick any method to solve it and you'll get x=5, y= -2

Use the distance formula to find the distance between each pair of points. Round your answers to the nearest hundredths place W
Elodia [21]

Answer:

The answer is

<h2>5.83 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  }  \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

W (-3,-5) and T (2,-2)

The distance between them is

|WT|  =  \sqrt{ ({ - 3 - 2})^{2} + ( { - 5 + 2})^{2}  }  \\  =  \sqrt{ ({ - 5})^{2} + ( { - 3})^{2}  }  \:  \:  \:   \\  =  \sqrt{25 + 9}  \\  =  \sqrt{34}  \:  \:  \:  \:  \:  \:  \:  \:  \\  = 5.830951

We have the final answer as

<h3>5.83 units to the nearest hundredth</h3>

Hope this helps you

6x-1/5 = 3/1 Solve for x in simplest form.
lawyer [7]
6x-1/5=3
add 1/5 to both sides
6x=1/5+3
convert 3 to fraction with 5 as denomenatory
3/1 times 5/5=15/5
6x=15/5+1/5
6x=16/5
divide both sides by 6
x=16/5 times 1/6
x=16/30
x=8/15

Find the area of the composite figure.
REY [17]
Answer: 174ft^2


Area of triangle: (bh)/2

A = (6*4)/2
A = 24/2
A = 12ft^2


Area of rectangle: LW

A = 18(9)
A = 162ft^2

Add area of rectangle and triangle together


A = 162ft^2 + 12ft^2
A= 174ft^2
