Answer:
(2, - 9 )
Step-by-step explanation:
Since 2 is the output when - 9 is input to f(x)
Then reversing the procedure, that is the inverse gives an output of - 9 for an input of 2.
(- 9, 2) is a point on the graph of f(x), then
(2, - 9) is a point on the graph o the inverse function 
(x)
Answer:
1/6
Step-by-step explanation:
(3 1/3)/20=(10/3)×(1/20)=10/60=1/6
Answer:
x=9, y=10. (9, 10). The two numbers are 9 and 10.
Step-by-step explanation:
3x+5y=77
x+y=19
------------------
3x+5y=77
-3(x+y)=-3(19)
---------------------
3x+5y=77
-3x-3y=-57
-------------------
2y=20
y=20/2
y=10
x+10=19
x=19-10
x=9
Answer:
m/(1 - .8)
Step-by-step explanation:
She read 80% of her emails, which is .8 of the total. So her unread emails would be 100% - 80% = 1 - .8
that means me can be written as:
m = (1 - .8)t
where t is the total
If we solve for t, we get:
t = m/(1 - .8)
