Answer:
(x, y) --> (y, x)
Step-by-step explanation:
The zeroes are
0, -5, 3 + i (and its conjugate)
The factors are
x (x + 5) (x - (3 + i)) (x - (3 - i))
Expanding...
(x² + 5x)((x - 3) - i) ((x - 3) + i)
(x² + 5x)((x - 3)² - i²)
(x² + 5x)(x² - 6x + 9 - (-1))
(x² + 5x)(x² - 6x + 10)
x⁴ - 6x³ + 10x² + 5x³ - 30x² + 50x
x⁴ - x³ - 20x² + 50x
Answer:
5/4
Step-by-step explanation:
Using coordinates (10,0) and (90,100)
Slope m = (y2-y1)/(x2-x1)
m = (100 - 0)/(90 - 10) = 100/80 = 10/8 = 5/4
