The numbers are complex numbers, and the sum of the complex numbers (-4 +i) and (10 - 5i) is 6 - 4i
<h3>How to evaluate the sum?</h3>
The expressions are given as:
(-4 +i) and (10 - 5i)
The sum is represented as:
Sum = (-4 +i) + (10 - 5i)
Open the brackets
Sum = -4 +i + 10 - 5i
Collect like terms
Sum = -4 + 10 +i - 5i
Evaluate the like terms
Sum = 6 - 4i
Hence, the sum of the complex numbers (-4 +i) and (10 - 5i) is 6 - 4i

Answer:
x = ±√10i (i outside the radical), or approximately ±3.62i, or no solution depending on your class.
Step-by-step explanation:
x^2 + 10 = 0
x^2 = -10
x = ±√-10
x = ±√10i (i outside the radical), or approximately ±3.62i.
The solution is not real.
If you meant x^2 - 10 = 0 then x = ±√10 or approximately ±3.62. This solution is real.

Answer:
x≤3 or x>10
Step-by-step explanation:
x≤3 because the dot is a solid dot at 3 and pointing backward toward numbers less than 3.
x>10 because the dot is an open circle pointing toward numbers greater than 10.
