Answer:-(9 - 4i) =
Step-by-step explanation:
Given the complex number 9 - 4i, the additive inverse is the number that when added to the original number, would equate to zero. Another term this may be known as is the additive identity. The additive inverse is simply:
(a + bi) = -(a + bi)
Given: 9 - 4i
-(9 - 4i) = -9 + 4i
Answer:
120
Step-by-step explanation:
Answer:
x = 84
Step-by-step explanation:
Sum of angles around a point = 360
Sum of given angles = 132+54+90 = 132+144 = 276
So, x must cover the angle remaining from 276 to form 360, which is
360-276 = 84degrees.

Answer:
-7 is your answer
Step-by-step explanation:
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other.
4 + y = -3
Subtract 4 from both sides
4 (-4) + y = -3 (-4)
y = -3 - 4
y = -7
-7, or (D) is your answer
