Which operations involving complex numbers have solutions represented by point A on the graph? PLEASE HELP

Alina [70]

Answer:

Option 3 and 4

Step-by-step explanation:

We have to find the solutions represented by point A on graph

The point A is represented by (-6,7i)

Lets check all options one by one

$2(1-2i)-(4+3i)\\= (2-4i)-(4+3i)\\=2-4i-4-3i\\=2-4-4i-3i\\=-2-7i$

This option is not correct

$2(1+2i)+(-4-3i)\\=(2+4i)-4-3i\\=2+4i-4-3i\\=2-4+4i-3i\\=-2+i$

This option is also not correct

$2(-1+2i)-(4-3i)\\=(-2+4i)-4+3i\\=-2+4i-4+3i\\=-2-4+4i+3i\\=-6+7i$

This solution is same as point A so this option is correct

$(-2+4i)+(-4+3i)\\=-2+4i-4+3i\\=-2-4+4i+3i\\=-6+7i$

Solution same as point A so this is correct option.

$(-2-4i)+(4-3i)\\=-2-4i+4-3i\\=-2+4-4i-3i\\=2-7i$

Not correct

The correct options are option no 3 and 4 ..

Write an equation in slope-intercept form for the line that passes through (5,3) and is parallel to x+3y=6.

Grace [21]

Answer:

y= $-\frac{1}{3} x+\frac{14}{3}$

Step-by-step explanation:

A parallel line would have the same left hand side, different right hand side.

Use the point to determine the new right hand side.

Find the Value of 8 1/3

Inessa [10]

$8^{ \frac{1}{3} } = \sqrt[3]{8} = 2$

$8^{ \frac{2}{3} } = \sqrt[3]{8^2} = \sqrt[3]{64} = 4$

What is the length of YZ?

Bogdan [553]

Answer: C

Hello,

Step-by-step explanation:

WZ=7-3=4

YW²=XW*WZ=3*4=12 ==> WY=2√3

In the right triangle YWZ, using the Pythagorean's theorem:

YZ²=WY²+WZ²=12+4²=28

YZ=2√7≅5.29150....
