Answer:
No it is not
Step-by-step explanation:
well if you see any number that is could be written as a fraction is rational. square root of 9 is 3, but in this case the square root of 2 is irrational, so it is a irrational number.
The correct match will be closest to zero = x-y , greatest value = x + y and least value = -x
<h3>What is graph?</h3>
A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.
The vertical line is representing the data from 0 to 8 positive side and 0 to -8 negative side. We can see that the closest value to zero will be x-y
the least value will be -x and the greatest value is x + y.
Each interval is of unit 2 so the values x and y will be 4 and 2 respectively
closest to zero = x-y = 4-2 = 2
greatest value = x + y = 4+2 = 6
least value = -x = -4
Therefore the correct match will be closest to zero = x-y , greatest value = x + y and least value = -x

Answer: addition property of equality
Step-by-step explanation:
To determine the extent of how many times greater is the number of bacteria in petri dish A than petri dish B, we simply have to take the ratio of the two.
1.75 x 10^18 / 6.25 x 10^15 = 280
So the bacteria in petri dish A is 280 times larger.
In scientific notation:
2.8 x 10^2
Hope this helps :)
