Part a y=95x
Part b 285=95•3
Part c ?
Hope I helped sorry I don't know how to do the last one!
The 4x's get eliminated because they are opposite. So just add 10+15= 25
3? Because a significant figure includes all digits except leading zeros or trailimg zeros. So if you take the zeros away you only have 3 numbers
The first two numbers are rational, because they are rational numbers with a finite number of decimal digits.
The third number is also rational, because 
, which is integer, and thus rational as well.
We can't say that the fourth number is rational, because we don't know how the number continues. A decimal number is rational if its decimal digits are finitely many, or if they show some periodicity. This doesn't seem the case, so the number may be irrational.
The last number is rational, because it is a periodic decimal number, and as such it admits a fraction that generates it.
Answer:
Since c=0 there is no horizontal shift
Since f(x) = g(x) +3 we are shifting it up 3 units
Step-by-step explanation:
g(x) = (x-2)^2
f(x)= g(x) +3
f(x) = g(x+c) means it is a horizontal shift
c>0 moves it left c units
c<0 moves it right c units
Since c=0 there is no horizontal shift
f(x) = g(x) +c means it is a vertical shift
c>0 moves it up c units
c<0 moves it down c units
Since f(x) = g(x) +3 we are shifting it up 3 units
