Question

Can someone please help me

Answer 1

Explanation:

`\displaystyle\\12-15x > 22\\12-15x+15x > 22+15x\\12 > 22+15x\\12-22 > 22+15x-22\\-10 > 15x\\Divide\ both\ parts\ of \ the \ equation\ by\ 15:\\-(10)/(15) > x\\\\-(5*2)/(5*3) > x\\\\-(2)/(3) > x \\\\Thus,\\\\x < (-2)/(3)`

Answer: A

`\displaystyle\\4\leq 3x+10 < 19\\\\4-10\leq 3x+10-10 < 19-10\\\\-6\leq 3x < 9\\\\Divide\ the\ inequality\ by \ 3:\\\\-2\leq x < 3\\\\Answer:\ -2\leq x < 3`
