Answer:
A=m-n-p
Step-by-step explanation:
So solve for a, we have to isolate it on one side, so -a=n+p-m. So a=m-n-p
If every shelf has the same amount of books, then it can be seen as proportional because one shelf has 43 and 2 have 86, and it keeps going up in a consistent way.
so 43/1 = 86/2 .
Happy studying ^-^
Answer:
(-10, 0) and (0,-5)
Step-by-step explanation:
For the function 
find x-intercept and y-intercept:
1. when y=0, then
2. when x=0, then
You get two points (-10, 0) and (0,-5). Plot them on the coordinate plane and connect, obtained line is the graph of the linear function 
97/50 would be multipled by 2 to get 0.196. You multiply by 2 to make it easier
Fun fact
if f(a)=b then f⁻¹(b)=a
so
if f⁻¹(b)=a then f(a)=b
so we find f(x)=27 and the solve for x
f(x)=3x=27
3x=27
divide both sides by 3
x=9
so if f(9)=27 then f⁻¹(27)=9
problem solved
answer is 9
