Line a can be rewritten as
.. 2y -x = 12
The coefficients of y and x match those of line b, so lines "a" and "b" are parallel.
Condense z₁ and z₂ into their exponential forms:
z₁ = 3 (cos(π/4) + i sin(π/4)) = 3 exp(i π/4)
z₂ = 7 (cos(3π/8) + i sin(3π/8)) = 7 exp(i 3π/8)
Then the quotient of z₁ and z₂ is
z₁ / z₂ = 3/7 exp(i (π/4 - 3π/8)) = 3/7 exp(-i π/8)
and in trigonometric form,
z₁ / z₂ = 3/7 (cos(-π/8) + i sin(-π/8))) … … … D
Answer:2x+y
Step-by-step explanation:
If x = 4i, x = 2, and x = -2, then your factors are (x - 4i), (x - 2), (x + 2), and also (x + 4i) because if 4i is a factor then -4i is as well.
Answer:
Step-by-step explanation:
Start by combing the terms on the right. 3b - 8 = 3b - 2 because 7b - 4b is going to equal 3b
You are now officially stuck. The moment you try and put the 3b's on the same side of the equation, they will cancel out. There is no unique solution.
