Answer:
1. 3.14
Step-by-step explanation:
If we have

That just equals

For example, consider function

The inverse of that function is




So

If we compose the function, f(x) into f^-1(x).
We get

That proof of that.
1. Here x=f^-1(3.14)and f(3.14) cancel out so the answer is 3.14
2. We first find f(-7) which is -12,
We then find f(-12)= 5 so the answer here is 5.
Answer:
B. 20 years
Step-by-step explanation:
By using the process of trial and error, if Gina is 20 years old, that would mean her sister is 29 years old. This is because 20+9 is equal to 29. 29+20 sums up to 49.
Answer:
The next in the first pattern is 15.
The next in the second pattern would be 3.
The next in the third pattern would be 32.
Step-by-step explanation:
In the first pattern, you can notice that the terms keep going up by 3. As a result, the next one is 3 higher (12 + 3 = 15)
In the second pattern, the next number is always half of the number before it. (6 * 1/2 = 3)
The last pattern shows each number being 10 less than the one before it. (42 - 10 = 32)
