Answer:
Step-by-step explanation:
- The inverse function
of a function 
must meet that if 
, then 
. - To find the inverse function one can clear out x from the initial equation, and once obtained an expression x=f(y), replace x by y, where y=f(x).
- In this case,
. - To find the inverse function, we clear out x, as follows:
⇒
⇒
. - Now that we have clear out the value of x as a function of y, we just have to replace x by y: , which is the inverse function we have been looking for.
- To corroborate the function is correct, we can use the fact that , then . If we take x=1, in the first equation
. If now we replace b=2/3 in the inverse function we obtain 
Answer:
A = 140
Step-by-step explanation:
You figure out the amount of chocolate doughnuts sold by multiplying 2/3 by 7 1/4
first you change 7 1/4 to an improper fraction:
7 1/4= 29/4
now multiply 2/3×29/4 by multiplying the two numerators then putting that over the two denominators multiplied: (2×29)/(3×4)=58/12
now simplify:58/12=4 10/12= 4 5/6
the answer is Stanley's doughnut shop sold
4 5/6 trays of chocolate doughnuts
