The answer is:  [B]:  -4  .
_____________________________
Here is the problem:
_____________________
 "Find f(3)."
_______________________
    f(x) = \left \{ {x + 5 ;   if  x \ \textless \ -2 ;  \atop {-4; if x  \geq -2 ;}} \right. ;
______________________________________
Since we are asked to find:  " f(3)" ;  we consider the number, "3", which is GREATER THAN OR EQUAL TO "-2" ; (that is,  " 3 \geq -2" ;
 and f(x) = -4  if x \geq  -2 . 
_____________________________________________________
So, in this case, f(x) = f(3) =  -4 ; which is: "Answer choice: [B] ".

Which expression represents the calculation “subtract 4 from 12, then divided by 8”? A) 4 ÷ (12 − 8) B) (12 − 4) ÷ 8 C) (4 − 12)
Svetlanka [38]

The answer is B

As the question states that you need to "subtract 4 from 12" that means that you are taking 4 away from 12, so it would be 12-4.

Then it says to divide by 8. This means that for the subtraction to happen first, it must be withing parenthesis, so that would make the expression become

(12-4)÷8
