When you find the GCF (Greatest Common Factor), which is 6 you simplify both by 6 and get 4x-13y
Answer:
y=1.5 that what i got okay
In the given you wrote -2, whereas it should be -2i
z = a + bi and in trigo form | z |.(cos Ф + i.sin Ф).
z = 0 -2i → | z |.(cos Ф + i.sin Ф)
Now let's calculate z:
z² = a²+b² → z² = 0² (-2.i)² → z = -2(i)² →z= -2(-1) → z = |2|
tan Ф = b/a = -2/0 → tan Ф → - ∞ ↔ Ф = -90° or Ф = 270°
then the - 2 I ↔ |2|(cos 270° + i.sin 270°)
14/70 in it's simplest form is 1/5
hope this helps :)
Let's solve your equation step-by-step.
