The answer is C.

a is a real number in this case, and bi is an imaginary number because i is an imaginary number.

Answer:

Option C is correct.

Step-by-step explanation:

Given that a complex number is a number of the form a+bi

we have to choose the correct statement.

As we know,

A complex number is a number expressed in the form of a+bi where a and b are real numbers and

i=\sqrt{-1}

which is imaginary.

Hence, we say that a is a real number and bi is an imaginary number.

Option C is correct.

HELP PLS<br> Solve for x<br> x=[?]<br> 3x + 2 6x - 20
Sloan [31]

Step-by-step explanation:

Remember that the sum of angles on a straight line are supplementary. (180°)

Therefore 3x + 2 + 6x - 20 = 180.

=> 9x - 18 = 180

=> 9x = 198

=> x = 22.

When a fraction is negative are both the numerator and the denominator negative?
kykrilka [37]
Not necessarily, it could be either the numerator or the denominator. For example, -3/4 (lets pretend that its one on top of the other) either the three or the four could be negative but not both. If both the numerator and denominator were negative, they would cancel each other out, making it a positive question. So to answer your question, it is no.

Please helppp i need this done and i dont know what to do

Answer:

FRACTION                               DECIMAL

1/5( 1*2/5*2=2/10)                         0.2

3/10                                               0.3

1/2(1*5/2*5=5/10)                          0.5

7/10                                              0.7

3/4(3*25/4*25=75/100)               0.75

<u><em>NOTE</em></u>:   To conert a fraction into decimal, it is required that the denominator be changed into 10, 100, 1000 and so on.....   By changing the denominator, we have to first select the appropriate number by which you will be able to convert it into 10, 100 or 1000, and you are also required to multiply that number with the denominator as well as numerator. In the first question, 1/5 we can convert the denoinator into 10, 100 or 1000 as the denominator is 5, whatever you choose, the answer will be correct, so, 1*2/5*2 gives 2/10. Since 10 has one zero, the decimal point moves one time towards the left, which gives 0.2. And you can do the rest according to this way, considering the number of zeroes.
