You are buying two kinds of notebooks for school. a spiral notebook costs $2, and a three-ring
notebook costs $4. you must have at least six notebooks. the cost of the notebooks can be
no more than $20.
given the graph of the linear system, which systern is the solution of the real-world problem?

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.

the correct answer is x/3+10≥32

hope this !
