Answer:
The inverse f-1(x) = ( x - 2) / 2.
Step-by-step explanation:
Let 2x + 1 = y
Now find x in terms of y:
2x = y - 1
x = (y - 1) / 2
Replace the x by the inverse f-1(x) and the y by x, so we have:
f-1(x) = ( x - 2) / 2.
Let's assume
x represents the number of $25 tickets
y represents the number of $50 tickets
A total of 1,250 tickets
so, we get
![x+y=1250](https://tex.z-dn.net/?f=x%2By%3D1250)
So, cost of $25 tickets is 25x
So, cost of $50 tickets is 50y
Total cost of tickets =(cost of $25 tickets)+(cost of $50 tickets)
Total cost of tickets =25x+50y
we are given
worth $50,000, were sold
so, we get equation as
![25x+50y=50000](https://tex.z-dn.net/?f=25x%2B50y%3D50000)
we get system of equations as
![x+y=1250](https://tex.z-dn.net/?f=x%2By%3D1250)
..............Answer
Answer:500
Step-by-step explanation:26,000/52=500 i did<em> $26,000</em> divided by 52 because there are<em> </em><em>52 weeks in a year</em> and it gave me <em>500</em> so that is how i got the answer
