Answer:
-3
Step-by-step explanation:
Given the function f(x) = -(-x)
we want to evaluate f(-3)
What we do simply here is substitute the value of -3 for x in the equation
That would be ;
f(-3) = -(-(-3)) = -(3) = -3
There are 10 rooms per floor if there are 30 floors then there are 300 rooms
1 x 1 = 1
1 x -5 = -5
So, -5/7
