<h3><u>Solu</u><u>tion</u><u>:</u><u>-</u></h3>

Firstly we must know what complex Number is .

Complex number - The number in the form of a + bi ,where a is real part and bi is Imaginary part is called a complex number . Also here value of i ( read as iota ) is √-1 . It can't be represented on the number line and is represented on the Argand Plane .

So , here the complex number given to us is 7 + 9i .

So , it can be written as ,

= 7 + 9i .

= 7 + 9√-1 .

= 7 + √9 × √9 × √-1 .

= 7 + √ 81 × -1 .

= 7 + √-81 .

\boxed{\green{\bf\purple{\dag }Hence\: correct\: option\:is\:[d].}}

Nooooow this is the story all about how my life got flipped turned upsidedown and id like to take a minute so sit right there and ill tell you how i became the prince of a town called Bel Air.

In west Philadelphia born and raised on the playground is where i spent most of my days. chillin out maxin relaxin all cool and all shootin some b-ball outside of the school

when a couple of guys, they were up to no good, started making trouble in my neighborhood. i got in one little fight and my mom got scared she said "youre moving with your auntie and uncle in bel air"

i begged and pleaded with her day after day, but she packed my suit case and sent me on my way. she gave me a kiss and then gave me my ticket i put my walkman on and said "i might as well kick it."

first class yo, this is bad drinkin orange juice outta champagne glass is this what the people of bel air be livin like? hmmm this might be alright. but wait i hear theyre prissy, bourgeois, all that. is this the type of that they just send this cool cat?

i dont think so, ill see when im there. i hope theyre prepared for the prince of bel air. well the plane landed and when i came out there was a dude who looked like a cop standing there with my name. i aint trying to get arrested yet i just got here i sprang with the quickness like lightning, disappeared.

i whistled for a cab and when it came near the license plate said fresh and it had dice in the mirror. if anything i could say that this cab was rare. but i thought "nah forget it- yo homes to bel air!"

i pulled up to a house about 7 or 8 and i yelled to the cabbie "yo homes smell ya later!" i looked up at my kingdom, i was finally there. to sit on my throne as the prince of bel air.

-1/2x+1=1 1/2x+17/2<br> I NEED HELP ON THIS PLEASE HELP<br><br> THANK YOU, SO, MUCH.
Pani-rosa [81]

Answer:

 x = -5/4 = -1.250

Step-by-step explanation:

Step  1  :

           17

Simplify   ——

           2  

Equation at the end of step  1  :

      1          11    17

 ((0-(—•x))+1)-((——•x)+——)  = 0  

      2          2     2  

Step  2  :

           11

Simplify   ——

           2  

Equation at the end of step  2  :

      1          11    17

 ((0-(—•x))+1)-((——•x)+——)  = 0  

      2          2     2  

Step  3  :

Adding fractions which have a common denominator :

3.1       Adding fractions which have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

11x + 17     11x + 17

————————  =  ————————

   2            2    

Equation at the end of step  3  :

         1                (11x + 17)

 ((0 -  (— • x)) +  1) -  ——————————  = 0  

         2                    2      

Step  4  :

           1

Simplify   —

           2

Equation at the end of step  4  :

         1                (11x + 17)

 ((0 -  (— • x)) +  1) -  ——————————  = 0  

         2                    2      

Step  5  :

Rewriting the whole as an Equivalent Fraction :

5.1   Adding a whole to a fraction

Rewrite the whole as a fraction using  2  as the denominator :

        1     1 • 2

   1 =  —  =  —————

        1       2  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

5.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

-x + 2     2 - x

——————  =  —————

  2          2  

Equation at the end of step  5  :

 (2 - x)    (11x + 17)

 ——————— -  ——————————  = 0  

    2           2      

Step  6  :

Adding fractions which have a common denominator :

6.1       Adding fractions which have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

(2-x) - ((11x+17))     -12x - 15

——————————————————  =  —————————

        2                  2    

Step  7  :

Pulling out like terms :

7.1     Pull out like factors :

  -12x - 15  =   -3 • (4x + 5)  

Equation at the end of step  7  :

 -3 • (4x + 5)

 —————————————  = 0  

       2      

Step  8  :

When a fraction equals zero :

8.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 -3•(4x+5)

 ————————— • 2 = 0 • 2

     2    

Now, on the left hand side, the  2  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  -3  •  (4x+5)  = 0

Equations which are never true :

8.2      Solve :    -3   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

8.3      Solve  :    4x+5 = 0  

Subtract  5  from both sides of the equation :  

                     4x = -5

Divide both sides of the equation by 4:

                    x = -5/4 = -1.250
