Answer:
7/30
Step-by-step explanation:
Answer:
To find the distance between two points, use the distance formula.
It will be the square root of (x2-x1)squared + (y2-y1)squared.
Use (3,-4) as x1, y1. Use (5,1) as x2, y2.
We get the square root of (5-3)squared + (1- -4)squared.
That gives us the square root of 2 squared + 5 squared.
Now we have the square root of 4 + 25, = the square root of 29.
That is the distance between the two points
Step-by-step explanation:
The answer is y-3=1/2(x-1)
Answer:
see explanation
Step-by-step explanation:
Given
(a + bi)(a - bi) ← expand using FOIL
= a² - abi + abi - b²i² → i² = - 1
= a² + b²
Since a and b are any real numbers, then
a² + b² is a real number
B
When a complex number is multiplied by its conjugate the result is always real.
P+4 because 4 more means plus
