Answer:
x / -9 = -16
Step-by-step explanation:
42%. It is opposite angles to the angel that says 42
Answer:
- no real solutions
- 2 complex solutions
Step-by-step explanation:
The equation can be rearranged to vertex form:
x^2 -4x = -5 . . . . . . . . . subtract 4x
x^2 -4x +4 = -5 +4 . . . . add 4
(x -2)^2 = -1 . . . . . . . . . show the left side as a square
x -2 = ±√-1 = ±i . . . . . . take the square root; the right side is imaginary
x = 2 ± i . . . . . . . . . . . . . add 2. These are the complex solutions.

<em>Comment on the question</em>
Every 2nd degree polynomial equation has two solutions. They may be real, complex, or (real and) identical. That is, there may be 0, 1, or 2 real solutions. This equation has 0 real solutions, because they are both complex.
3/4+z=5/6
Find the common denominator which is 12 for 3/4 and 5/6.
Multiply by 3 for 3/4.
Multiply by 2 for 5/6.
3(3)/4(3)=9/12
5(2)/6(2)=10/12
9/12+z=10/12
Move 9/12 to the other side. Sign changes from 9/12 to -9/12.
9/12-9/12+z=10/12-9/12
z=1/12
Answer: z= 1/12
