Step-by-step explanation:




Swap x and y

Answer:
(4 , - 35)
Step-by-step explanation:
X²-8x-19 =(x-4)² -35
y = a (x-h)² + k a=1 , (h , k) -> (4 , - 35)
Answer is 0
the slope formula is y2-y1 / x2-x1
plug in (1,5) and (2,5)
5-5 / 2-1
0/1 = 0
Answer:
= 21i
Step-by-step explanation:
√-9 = 3i
= 7 . 3i
Multiply the numbers: 7 . 3 = 21
= 21i
