Additive inverse is the number you add to a given number to make the sum zero. The addition of both the number must be zero to make both numbers additive inverse.. The additive inverse of the given complex number is

-9+4i

<h3>Addictive Inverse</h3>

Addictive Inverse-Additive inverse is the number you add to a given number to make the sum zero. The addition of both the number must be zero to make both numbers additive inverse.

Let an example, if we take the number 10 and add -10 to it. Thus -10 is the additive inverse of the number 10.

Here, the given number is a complex number. A complex number is a number of the form a + bi, where a and b are real numbers. The given function is,

9-4i

The additive inverse of the above number is,-9+4i

Add both and check by equating with zero,

9-4i+(-9i+4)=0

9-4i+-9i+4=0

0=0

Hence, the additive inverse of the given complex number is -9+4i.

Find the measures of each angle. Supplementary angles with measures (2x+3) and (3x+2). A. 64 and 116. B. 53 and 127. C. 63 and 1
const2013 [10]

Supplementary means adds to 180 degrees as all the choices do.


2x + 3 + 3x + 2 = 180


5x + 5 = 180


5x = 175


x = 175 / 5 = 35


2(35)+3 = 73

3(35)+2=107


Choice D

What is the vaIue of x?
Genrish500 [490]

Answer:

x=19

Step-by-step explanation:

You make your equation, 7x-8=6x+11.

Now you subtract 11 from both sides, so that now the equation is 7x-8-11=6x+11-11, or 7x-19=6x.

You need to now subtract 7x from both sides, so that it's 7x-19-7x=6x-7x, or -19=-x.

After that, you just reverse it so that it's positive, so x=19.
