Answer:
Use z = a +bi = IzI (cos (Ф) + i sin (Ф)) to find the trigonometric form. √2+∛ / 2 (cos (0) + i sin (0))
Step-by-step explanation:
Julie wants to express $108 in 6 weeks as a unit rate.
Her errors are:
$108 = $54 (Not true)
6 weeks = 3 weeks (Not true).
Instead,

The correct unit rate is 18 $/week.
X=-7y+34
x+7y=32
To begin with make the two problems the same kind of problem. By adding 7y on both sides for the first problem.
x+7y=34
x+7y=32
So the correct answer would be no solution because it's the same problem and it can't equal to different answers.
Answer:
add a zero at the end of the number. 5x10=50. 60x10=600. 700x10=7000 etc.
Step-by-step explanation:
Answer:
x = - 71
Step-by-step explanation:
x - 12 = - 83
+12 +12 (adding 12 to both sides)
x = - 71
