Answer:
5/12
Step-by-step explanation:
2 2/5 = 12/5 so its reciprocal is 5/12
Reciprocals are fractions that are basically "flipped". You flip the denominator to the numerator and vice versa.
Ok, so lets evaluate this here:
2/3 (x - 6) - y Let's do the first part: 2/3 (x - 6)
If X = 9 then we subtract 6 from 9 and get 3. Then we multiply
3 by 2/3 and get 2.
Then lets do the 2nd part: 2 - y.
So if y = 5/6, we can first convert 2 into an improper fraction in sixths and have 12/6. Then. we just have to do 12/6 - 5/6 and subtract the numerators and end up with 7/6. The final answer is A, hope this helps!
The equation is:

f ( - 1 ) = 4 * 1/25 = 4/25 ( false )
f ( 0 ) = 4 * 1 = 4 ( false )
f ( 1 ) = 4 * 25 = 100 ( false )
f ( 2 ) = 4 * 5 ^4 = 4 * 625 = 2500 ( correct )
Answer:
D ) ( 2, 2500 )
