Start where the x and y axes cross.
Go 5 units to the left on the x (horizontal axis) and then go 9 units up from there.
Put a dot in that spot.

What is the complex conjugate of -3-9i?
For any number (a + bi), its conjugate is (a - bi), so the real part stays the same, and the imaginary part is negated.For this one, conjugate of [-3 - 9i] is: -3 + 9i
What is -9i 2-I as a complex number?
Unfortunately, due to the limitations of browsers, most mathematical symbols get removed and it leaves gibberish that is impossible to answer Please edit/re submit your question with a full sentence of what you want solved, replacing mathematical symbols by words, eg plus for +, equals for =
How do you factor 81 16k2?
If that's 81 - 16k2, it factors neatly as the difference of squares into (9 - 4k)(9 + 4k)If that's 81 + 16k2, it factors to (4k -9i)(4k + 9i) where i is the square root of negative one.
What is the factor trinomial of y2 -9y 81?
That doesn't factor neatly. Applying the quadratic equation, we find two imaginary solutions: (9 plus or minus 9i times the square root of 3) divided by 2y = 4.5 + 7.794228634059948iy = 4.5 - 7.794228634059948iwhere i is the square root of negative one.
Is the square root of -81 rational or irrational?
Since it is the square root of a negative number, it is actually imaginary, neither rational nor irrational. It is equal to 9i, or 9 times whatever the square root of negative one is.square root of -81 = square root of 81 times i = 9i
What is the complex conjugate of 8 plus 9i?
It would be 8 minus 9i or 8-9i
How do you factor a to the second power plus 81?
Factorize: a2 + 81 It doesn't look like it in its current form, but this can be changed to be a difference of two squares which can then be factorize. However to do this, we will need to use complex numbers. a2 + 81 = a2 - (9i)2 = (a + 9i)(a - 9i) (where i is the square root of -1)
What is the sum of (7 plus 3i) plus (8 plus 9i)?
(7 + 3i) + (8 + 9i) = (7 + 8) + (3i + 9i) = (7 + 8) + (3 + 9)i = 15 + 12i Which can also be written as: 15 + 12i = 3(5 + 4i).
What is the complex conjugate of -3-9i?
For any number (a + bi), its conjugate is (a - bi), so the real part stays the same, and the imaginary part is negated.For this one, conjugate of [-3 - 9i] is: -3 + 9i
What is 4-2i divided by 5-9i?
To solve this, you should multiply both terms of the division by (5 + 9i), using the rules of multiplication for complex numbers.
What is the magnitude of the complex number 3-9i?
Mag(3 - 9i) = sqrt(32 + 92) = sqrt(9 + 81) = sqrt(90) or 3*sqrt(10)

8 plus 6i-2 plus 3i?
(8+6i)-(2+3i)=6+3i 8+6i-2+3i=6+9i
What is the absolute value of a complex number?
The absolute value of a complex number a+bi is the square root of (a2+b2). For example, the absolute value of 4+9i is the square root of (42 + 92) which is the square root of 97 which is about 9.8489 (The absolute value of a complex number is not complex.)
