Answer:

Step-by-step explanation:
The first thing that would need to be done is solving for y. This problem has already done this. The next step is to exchange y for 
That is all. This would mean that the function notation for the equation would be: 
Perfect squares are n² where n is a whole number
whole numbers are like 0,1,2,3,4,5,6, etc
no decimal or fractions
we can do that be looking at the perfect squares we know
2²=4
3²=9
4²=16
5²=25
6²=36
7²=49
8²=64
etc
so we see 47 is between 6² and 7²
therefor, for n²=47, n is between 6 and 7 and is therfore not a whole number
that makes 47 not a perfect square
Answer: 154: 200 145: 100
Step-by-step explanation:
If the number next to the place value is 5 or more you round it up. Like I did 154. But if the number is less that 5 you put everything to zero EXCEPT for the place value you are rounding. Good Luck
