We set up a proportion: ?/42,000= 3/5
Cross multiply:
5*?= 3*42,000
⇒ ?= 3*42,000/5= 25,200
3/5 of 42,000 is 25,200~
Answer:
Step-by-step explanation:
The inverse of a function is when the x and y are swapped. So the first step is to write f(x) as y and then swap the x and y
Original Equation:
write f(x) as y (since that's what it represents)
Swap x and y
Square both sides
Add 1 to both sides
So this gives you the equation:
Im not sure either but double check the equation again
