hope this helps!
For this case we can use the Pythagorean theorem to solve the problem.
We have then for the following complex number:
![-3 + 4i ](https://tex.z-dn.net/?f=-3%20%2B%204i%0A)
Using the Pythagorean theorem:
![\sqrt{(-3)^2+(4)^2}](https://tex.z-dn.net/?f=%20%5Csqrt%7B%28-3%29%5E2%2B%284%29%5E2%7D%20)
Rewriting we have:
Answer:
A complex number that has an absolute value of 5 is:
A)–3 + 4i
Answer:
B
Step-by-step explanation:
when you flip across the y axis you change the signs of the x coordinate but not the y coordinate.
