Final answer:
After substituting -10 into the function f(a) = 4a - 5, and adding -10, the result is -55, which does not match any of the provided options.
Step-by-step explanation:
To solve for f(-10) when f(a) = 4a - 5 and then add (-10) to the result, we substitute a with -10 in the function:
f(-10) = 4(-10) - 5
= -40 - 5
= -45.
Now adding -10:
-45 + (-10)
= -55.
Therefore, f(-10) + (-10) is -55, which is not one of the options provided (A. 45/14, B. 19, C. 35/6, D. 14/45). Either the function provided is incorrect, or there may be an error in the question itself.
