ANSWER

Yes

EXPLANATION

The number

3i

can be rewritten as

0 + 3iThis is of ty form

z = a + bi

where 0 is the real part and 3i is the imaginary or complex part.

3i

is therefore a complex number. It is purely imaginary because the real part is zero.

Remember that a complex number has the form a + bi. You need to figure out what a and b need to be. Since −3i is an imaginary number, it is the imaginary part (bi) of the complex number a + bi. This imaginary number has no real parts, so the value of a is 0.

What are the values of x and y in the parallelogram?
postnew [5]

9514 1404 393

Answer:

  x = 60

  y = 30

Step-by-step explanation:

Adjacent angles are supplementary.

  (5x -180) +x = 180

  6x = 360 . . . . . . . . . . add 180, collect terms

  x = 60 . . . . . . . . divide by 6

Opposite angles are congruent.

  2y = 60 . . . . . . 2y = x

  y = 30 . . . . . . . .divide by 2

The value of x is 60; the value of y is 30.

How are the expressions 8-15 and 8-(-15)?how are they different?
zmey [24]

8 - 15 means subtract the positive number 15 from 8.

8 - 15 = 8 + (-15) = -7

8 - (-15) means subtract the negative number -15 from 8.

Subtracting a negative number is the same as adding a positive number.

8 - (-15) = 8 + 15 = 23

8 - 15 = -7, and 8 - (-15) = 23. The expressions mean different operations and have different answers.
