Answer: C the set of all integers, the set of all rational numbers, and the set of all real numbers
Step-by-step explanation: The value of square root of 9 is ±3. This means that there two answers to square root of 9: 3 and -3.
As far as 3 is concerned, it is one of the elements of the natural number set. It is already known that natural numbers are also whole numbers, also integers, also rational numbers, and also real numbers.
As far as -3 is concerned, it is not a natural number since the set of natural numbers does not contain negative numbers. -3 is an integer. Which means that -3 is also a rational number and also a real number.
After identifying the common sets and taking the intersection of both the above classifications, it yields the set of all integers, the set of all rational numbers, and the set of all real numbers

dunno wat fraction is
pick last option
Answer:
B
Step-by-step explanation:
There is no change in cost, so the slope stays the same. since the a dependent variable is cost, it stays on the y axis, and the amount of photocopies is on the x axis. The total amount of money for 8 copies is $1.60, so you would just plug those into the graph and find B to be correct.
