Good luck...
Rate of change is slope
So change in y/change in x
150/3=50
Not exactly sure but I think it's false hope this helps
Answer:
paying $7.25 per sq feet
Step-by-step explanation:
So we can start off by solving the area:
12*13=156
so the total area is 156 feet sq
the first deal:
156/7.25= about $21.52
the second deal:
156/6.75= about $23.11, however with the installation fee, it will cost even more.
To find the inverse of a function you need to isolate the x

after you are done replace every x with y and every y with x (it's optional, i personaly don't do it but you need to do it if your teacher tells you so):
-10x+5=y
