If the weight of the little brother is x, then the weight of  Charles is x + 9
The equation that can be used to determine what each one weighs is:
x + (x + 9) = 99.
Let us now solve it. 
x + x +9 = 99
2x + 9 = 99
2x = 99 - 9
2x = 90
x = 90/2 
x = 45 
Little brother's  weight is 45 kg.
Charles'   weight  will be 45 + 9 =  54 kg 
Adding these two weights will give 99kg

Transformation involves changing the form of a function.
The absolute value function is  
 
The parent function of the absolute value function is:

When the function is translated 2 units to the right, the new function is:

From the function to be wider than the absolute function, the function must be stretched by a factor less than 1.
The possible function from the list of given options is
