First do 3x3, which is 6.
Then do 1/2 x 1/2. Convert the 1/2's to .50's
Do .50 x .50. Start with 5 x 5, and get 25. Then move decimal 2 places over.
Now that you have 6 and .25, add them and get 6.25.
.25 as a fraction is, of course, 1/4
Your final answer should be 6 1/4

A segment in the complex plane has a midpoint at –1 + i. If the segment has an endpoint at –5 – 7i, what is the other endpoint?
saul85 [17]

Answer:

Option D. 3 + 9i

Step-by-step explanation:

We know that the formula to find the middle point is:

(\frac{x_1 + x_2}{2},\frac{z_1 + z_2}{2})

We know that the middle point is:

-1 + i

And the end point (x_2, z_2) is: -5 -7i

We wish to find the point x_1,z_1

So we can write the following equation

\frac{x_1 + (-5)}{2} = -1                   (i)

and

\frac{z_1 + (-7i)}{2} = i                     (ii)

Now we clear x_1 from equation (i) and clear z_1 from equation (ii)

For equation (i) we have:

-2 = x_1 -5 \\\\x_1 = 3

For equation (ii) we have:

2i = z_1 -7i\\\\z_1 = 9i

Then the initial point x_1, z_1 is: 3 + 9i

The correct answer is the last option 3 +9i
