Find the additive inverse of -7+5i.
1 answer:
Answer:
Required additive inverse is .
Step-by-step explanation:
Given number is .
Now we need to find about what is that additive inverse of the given number .
We know that if complex number is then it's additive inverse is given by
.
Basically we need to change the sign of imaginary term.
imaginary term in given number is +5i.
Changing sign of +5i gives -5i.
Hence required additive inverse is .

<h3>Further Explanation </h3>One variable linear equation is an equation that has a variable and the exponent number is one.
Can be stated in the form:
or
ax + b = c, where a, b, and c are constants, x is a variable
We complete the introduction for the task
Bruce retiled his kitchen. Originally, he bought three boxes of tile with the same number of tiles in each. He ran out of tile and had to go back to get three extra boxes of tile. However, he only used two tiles from the last box to finish the job.
Felicia also retiled her kitchen. She bought five boxes of tile with the same number of tiles that were in each as Bruce’s boxes. She also ran out of tile. She had to go back to the store and get an extra five tiles to finish the job.
We can translate those in to expression of One variable linear equation (x = number of tiles)
- Bruce
He bought three boxes ⇒ 3x
He only used two tiles from the last box ⇒ 2x + 2
Total tiles of Bruce used : 3x+2x+2 = 5x+2
- Felicia
She bought five boxes ⇒ 5x
She get an extra five tiles to finish the job. ⇒ 5 tiles
Total tiles of Felicia used : 5x+5
