Use subtitution method to solve the problem.
First, change y to the value of x in order to find the exact value of x.
x + y = 4
y = 4 - x
Second, subtitute y with 4 - x from the first equation
y = -x² + 2x + 4
4 - x = -x² + 2x + 4
move all terms to the left side
x² - 2x - x + 4 - 4 = 0
x² - 3x = 0
x(x - 3) = 0
x = 0 or x = 3
Third, now we have 2 values of x. Find the value of y for each of x
For x = 0
y = 4 - x
y = 4 - 0
y = 4
For x = 3
y = 4 - x
y = 4 - 3
y = 1
The solution is (0,4) and (3,1). The answer is option b

The cube root of 216 is 6
Depends how strong the bomb is. If the bomb is weak then you would most likely go up 20-30 floors. If the bomb is in the middle go to the stair case and prepare for impact. If the bomb is strong go down 40 floors if possible. If none of this is possible to do and you don't know what to do about it then you must do the following:
Cut all of the wires in the bomb. Get the bomb near of a wall or a window. If it is a window then throw the bomb out of the window. If it is a wall put it as close to the wall as possible gather all your coworkers and run off of the floor.
Hope this helps!
