Answer is choice C
The expression given is equivalent to -3i
============================================
Explanation:
Using a calculator, a reference sheet, or the unit circle, you'll find that:
cos(270) = 0
sin(270) = -1
So this means
z = 3(cos(270)+i*sin(270))
z = 3(0+i*(-1))
z = 3*0+3*i*(-1)
z = 0-3i
z = -3i
which is in a+bi form where a = 0 and b = -3

Answer:
"Equations can be multiplied by a constant to allow for elimination by addition or subtraction. This process is called Elimination by Multiplication. We multiply the first equation by "2" to prepare it for elimination by subtraction. Now that we know "x", we can use this information to solve for "y"."
