An elevator started on the ground floor. it went up 4 floors, down 4 floors, up 8 floors, and down 2. which expression matches the scenario? a= |+4|-|-4|-|+8|-|-2| b= (++) c= (+4)+(-4)+(+8)+(-2) d= |+4|+|-4|+|+8|+|-2|

maybe - definition of supplementary angles. im not sure. sorry

step-by-step explanation:

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.
