Aprinter makes more than 3 copies of a book every hour which graph represents the number of books made in 4 hours

D

Step-by-step explanation:

The answer is graph D because in the word problem it says, "more than three copies". We can also see that we need to find how many copies are made in 4 hours. Since it says more than and we do not have another number, we will multiply 3 and 4.

3 x 4 = 12

This is a line graph. An enclosed circle on a number would mean that this line includes the number. This circle is open, not enclosed so 12 is not a part of the line for graph D.

Since it says more than, this open circle makes sense, because it was more than 3 books, but not 4 books. This means it can range anywhere after 3. (examples: 3.1 books, 3.5 books, 3.8 books) this means it can also range anywhere after twelve.

This combined shows us that graph D is the answer.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
