The complex conjugate of something is essentially just taking the opposite sign of the imaginary part. The following are complex conjugates:
a + bi
a - bi
In this case the complex conjugate of 9 - 4i is 9 + 4i
Now we must add them together like so:
(9 - 4i) + (9 + 4i)
9 - 4i + 9 + 4i
^^^Combine like terms
(9 + 9) + (-4i + 4i)
18 + 0
18
As you can see when you add complex conjugates your answer will be a real number
Hope this helped!

Answer:
La pendiente de una línea es una medida de su inclinación. Matemáticamente, la pendiente se calcula como "subida sobre carrera" (cambio en y dividido por cambio en x).
Step-by-step explanation:
English: The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
Answer:

Hence, option B) is true.
Step-by-step explanation:
Given
g(x) = 2x-5
h(x) = x² - 2
To determine

In order to determine g(h(-8)), first we need to determine h(-8), so
substituting x = -8 in h(x) = x² - 2
h(x) = x² - 2
h(-8) = (-8)² - 2
h(-8) = 64 - 2
h(-8) = 62
so we can write

now, to determine g(62), substitute x = 62 in g(x) = 2x-5v
g(x) = 2x-5
g(62) = 2(62) - 5
g(62) = 124 - 5
g(62) = 119
so,

Therefore,

Hence, option B) is true.
Answer:
A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees. Vertical angles are two angles opposite from each other and those two angles are then equal.
Step-by-step explanation:
For example, if you took your typical graph with four quadrants your lines would intersect. The linear pairs are equal to 180 and the vertical angles are equal.
