If 40 maple trees were planted, how many beech trees would be planted?

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

the correct answer is x/3+10≥32

hope this !
