The answer would be 5 + 15i/2.
1. 5 + 3i/2 + 6i
2. 5 + (3/2i + 6i)
3. 5 + 15i/2.

0.329 is a rational number because the decimal stops. If it had continued on and on with no particular pattern, it would have been irrational. It can be a fraction too (329/1000)...
127.5 is a rational number because again the decimal ends. It can also be converted into a fraction which is another sign that it is rational (127 1/2)...
-89 is a rational number because negatives are rational numbers. It is also in the category of an integer, which means that is a rational number also...
The last one is a non-perfect square, which means no number squared could ever give you 101. When you solve for it, it is also a non-terminating decimal.
Answer:
b. y = −0.5x + 5.5
Step-by-step explanation:
Well first we need to find the slope of line CD.
To do that we'll use the following formula,

We'll use the points (1,1) and (3,5)
So y2 is 5 y1 is 1 so 5-1 = 4
3-1 = 2
<u>Slope = 2x</u>
If the slope of line CD is 2x we can cross out choices C and D.
Two lines that are perpendicular to each other have reciprocal slopes,
meaning is the slope of line CD is 2 then its perpendicular lines slope should be -.5.
If the perpendicular line goes through point (-1,6), the y intercept would be, 5.5.

<em>Thus,</em>
<em>the answer is option b. y = −0.5x + 5.5.</em>
<em>Hope this helps :)</em>
