Answer:
The choices were typed wrong, but we can find the inverse of each option.
For function 
the inverse is the same function 
, because an inverse of a function is where their composition gives the independent variable as unique result.
If we do that with each function, we have:
; where and , we have
So they are inverse.
For 
its inverse would be 
, because
For 
, its inverse is 
, because
For 
, its inverse is 
, because
There you have all inverses. Basically, if their composition results in 
, that means they are inverse.
Answer:
Third table
Step-by-step explanation:
For the relationship to be proportional
y/x = constant
First table y/x = 8/4 = 2 then 7/11 doesn't =2 so it is not
Second table y/x =52/5 = 5 then 49/7 doesn't =5 so it is not
Third table y/x = 3/6=1/2 then 5/10 = 1/2 then 7/14 = 1/2 it is proportional
Last table y/x = 6/3 = 2 then 11/8 doesn't =2 so it is not
Ratio of corresponding sides of triangle a to triangle b is a/b
Answer:
77
Step-by-step explanation:
to start off the "difference" is the way to say total in subtraction
you would have to subtract 87 and 10 to find the difference
87 - 10 = 77
77 is the difference between their times
