Answer:
To the first question the answer would be > because you can change -3/4 to -9/12. Since these are negative numbers -5 is greater than -9.
The answer the second one would be B because I change all the fractions to decimals and 6/11 equals 0.54545454 and goes on and on So it was the greatest number (in decimal form). Also negaitve numbers are the least. :) Hope this helps

If you are allowed to use a calculator then you only need to press the buttons.
Assuming you cannot use a calculator you need to use approximation techniques. First let us begin by finding the two closest numbers that are perfect squares. In this case 11^2 and 12^2 are the closest square numbers to 129.
11^2 = 121
12^2 = 144
We can already tell that the square root of 129 is closer to 11 than to 12.
Now we need to get even closer.
If you try squaring a number like 11.5 then you can get even closer to 129. When you square 11.5 you get 132.25. Already you can tell that the square root of 129 is close to the square root of 132.25 or 11.5
Now we can get even closer square the number 11.25 and keep on going until one of these numbers when squared is almost or exactly 129. I hope I helped, there really isn't a great way to do this without a calculator, or by using the graph of y=x^2
Answer:
Yes, it is a function
Step-by-step explanation:
anytime you want to test to see if the graph is a function, perform a vertical line test.
Basically if you drew a vertical line and the vertical line crosses the graph at only one point that means the graph is a function.
If it crosses on more than one point the graph is not a function.
