Answer:
Factor x^2−8x−48 using the AC method.
(x−2) (x+4)
Option D would probably be the right choice. Because x is the variable for coins, there would be x amount of quarters, and because there are 150 coins, 150 - x would be the remainder.
You have the original function as 2x-5
and you are given the value of x to be -1/2
Therefore, all you have to do is substitute the value of x in the function and calculate it as follows:
f(-1/2) = 2(-1/2) - 5 = -1 -5 = -6
