What exactly are u solving for c or h?
Answer:
-6
Step-by-step explanation:
y = -2 x -3/2 - 9
3 - 9 = -6
If i can see it right, it would be A because it starts at 30, then rises as the number of rooms increases.
Answer:
The ideal mechanical advantage (IMA) is 
.
Step-by-step explanation:
The ideal mechanical advantage is the ratio of length of longer lever 
to that of shorter lever 
IMA 
Please refer to the image attached.
We could see that the the resistance load moves 
cm towards the fulcrum so the distance of resistance load from fulcrum 
Now the as the effort force moves 
towards the fulcrum overall distance from the fulcrum to the effort force (load) 
Plugging the values of the distances in IMA formula we can have.
IMA 
.
So the IMA of the fulcrum (simple machine)
