Answer:
10 + 5i & 10 - 5i
Step-by-step explanation:
10 + 5i is still just 10 + 5i because we treat i like it's x.
Complex conjugate if I remember correctly is like a + or - form, so I believe 10 - 5i is correct?
Hope this helped.
Answer:
Purple line: 4
Red dashed line: 2
Blue line: 1/2
Step-by-step explanation:
The purple line is the steepest line, therefore it has the biggest constant of proportionality or slope. Since 4 is the biggest number among the others, we attribute it to the purple line (the one with the point C on it).
Think of it this way:

here
so 
The greater a is, the greater y is. So for any value of x, y will be become bigger and bigger if we increase the value of a.
Take for example this one:

Take
therefore
Now take
and take
therefore
When we increased this constant of proportionality, as you can see from 2 to 4, the value of y increase from 4 to 8.
Hope this is helpful. Think of it really carefully, and I'm sure you'll grasp the concept.
Answer:
-12
Step-by-step explanation:
12+(-12) is equal to zero.
Ax^2 + bx + c
An expression with a quadratic structure will have a term being raised to the second power
The function which represents a graph which has been vertically shifted by 3 units is; y= log (x) + 3.
<h3>Which function has been shifted by 3 units?</h3>
It follows from the task content that the graph which has been shifted vertically is to be identified.
For a vertical shift, it means that the y value of such graphs must have increased or decreased. This is However, evident in the equation y= log (x) + 3 and hence, is the solution.
