The absolute value of 7 would be 7
Answer:
correct
Step-by-step explanation:
negative integers are still rational numbers if it is a whole number or complete
Sorry for the chicken scratch
It says as x approaches negative infinity y approaches negative infinity and as x approaches positive infinity y approaches negative infinity
9/20
the numbers that would satisfy this are 15,16,17,18,19,20, 1,2,3
so there are 9/20
Answer:
z^2 + (-1 + 5·i)·z + 14 - 7·i = 0
(1 + 2·i)^2 + (-1 + 5·i)·(1 + 2·i) + 14 - 7·i = 0
(1 + 4·i - 4) + (-1 - 2·i + 5·i - 10) + 14 - 7·i = 0
0 = 0 --> true
z^2 + (-1 + 5·i)·z + 14 - 7·i = 0
(1 - 2·i)^2 + (-1 + 5·i)·(1 - 2·i) + 14 - 7·i = 0
(1 - 4·i - 4) + (-1 + 2·i + 5·i + 10) + 14 - 7·i = 0
20 - 4·i = 0 --> false
