Its is something give me more detail
Answer:
Step-by-step explanation:
for inverse of f(x)=2x+2
x=2y+2
x-2=2y
(x-2)/2=y
therefore the inverse f(x)=(x-2)/2
(7^2)x = 1
49x = 1
x = 1/49
Part B
7^0 = 1
so we have
1x = 1
x = 1
We have the next number

The expanded form of the number is

Also, we can verify that Alex was incorrect because if we do the sum of the expanded form that Alex calculated we obtain

Finally, the correct answer is
