To find the sum of $(-4+i)$ and $(10-5i)$, we need to add the real parts and the imaginary parts separately.<br /><br />The real part of $(-4+i)$ is $-4$, and the real part of $(10-5i)$ is $10$. Adding these together, we get $-4 + 10 = 6$.<br /><br />The imaginary part of $(-4+i)$ is $i$, and the imaginary part of $(10-5i)$ is $-5i$. Adding these together, we get $i + (-5i) = -4i$.<br /><br />Therefore, the sum of $(-4+i)$ and $(10-5i)$ is $6-4i$.<br /><br />So, the correct answer is $6-4i$.
