Juan has 20 books to sell. He sells the books for $15 each. The amount of money Juan makes from selling x books is represented by the equation y=15x
y
=
15
x

What is the theoretical range of the equation?

Question 2 options:

All multiples of 20 between 0 and 300, inclusive

All integers from 0 to 20, inclusive

All multiples of 15 between 0 and 300, inclusive

All real numbers

Well u would multiply 20 x 15 to find out the highest if the range which is 300 . So that knocks it down to B or D. But since they're $15 each, It would be based of the multiples of 15 making your answer B .

The range is all the y valuesor the f(x) values .

So the practical range would be the multiples of 15 between 0 and 300,Inclusive .

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1
