Definately option C
- As it's mentioned y=x+4 it must be function
- So in function every domain has its unique range.
- Hence here the slope is not constant
As
The graph shown is a parabola which is not y=x+4
So option C is wrong
Answer:
x=0
Step-by-step explanation:
Anything to the power of 0 = 1
2 square root x • 4x= 22
2x=22
x=11
Answer is 11

Answer:
Step-by-step explanation:
Hello, please consider the following.

So this is divisible by 3.
Now, to prove that this is divisible by 9 = 3*3 we need to prove that
is divisible by 3. We will prove it by induction.
Step 1 - for n = 1
4+17=21= 3*7 this is true
Step 2 - we assume this is true for k so
is divisible by 3
and we check what happens for k+1

is divisible by 3 and
is divisible by 3, by induction hypothesis
So, the sum is divisible by 3.
Step 3 - Conclusion
We just prove that
is divisible by 3 for all positive integers n.
Thanks
