Hey there! :) I only see two questions so I assume you need help with those two if I am not mistaken. So lets start out with number 9!
So, for number 9 we have 5/4- 5/8. Always when you don't have the same denominators( the bottom number) we must find common denominators. So since 4*2= 8 our common denominator is 8! So this is a piece of cake since 5/8 is already in eighths. So we multiply 5*2= 10 and 4*2 = 8 so 5/4 is 10/8. Then we do 10/8- 5/8= 5/8. We only subtract the numerator and the denominator stays the same.
On to number 10! We have 2/3- 2/7. So lets find a set of common denominator. We can do 21, since 3*7= 21 and 7*3= 21! So 2*7= 14 and 3* 7 =21. So for 2/3 we have 14/21. For the 2/7, we do the same thing as before 2*3= 6 and 7*3= 21. So, 2/7= 6/21. Then the last step! Subtract 14/21- 6/21= 8/21. Then we simplify if needed! We don't need to simplify because it can't go any lower.
I hope I helped and explained it well! :D
Answer:
f=2
Step-by-step explanation:
f(x-2)=2x-4
divide x-2 to 2x-4
f=2
f(2-2)=4-4
