you answer this you'll get 50 points but it has to be correct
Answer:
The answer is 6 – 4i
Step-by-step explanation:
Complex values:
Have the following format: a + bi
In which a is the real part and b is the complex part.
Addition:
Suppose we are going to add two complex numbers. We add their real parts, and their complex parts separatly.
So
(–4 + i) + (10 – 5i) = (-4 + 10) + i(1-5) = 6 - 4i
The answer is 6 – 4i
Answer:
(x − 5)² + (y − 4)² = 4²
(x − 5)² + (y + 4)² = 4²
Step-by-step explanation:
x=1 and x=9 are vertical lines. If both are tangent to the circle, then the circle has a diameter of 8, or a radius of 4, and the center of the circle is on the line x=5.
y=0 is the x-axis. Since the circle is tangent to that, the center of the circle is either 4 units above the x-axis or 4 units below.
So two possible equations of the circle are:
(x − 5)² + (y − 4)² = 4²
(x − 5)² + (y + 4)² = 4²
