Every daykatie looks for seashells on the beach. she has 28 shells in her collection. katie finds 12 more. write an ineuality to determine the number of days it will take to collect over 100 shells

Match the equivalent expressions. x - 3y + 12 12 - 3y - 2x + x + 2x 3x + 2y - 2x + y + 12 3y + 12 3x + y - 12 4y + 3y + 3x - 6y - 10 - 2 x + 3y + 2x - 3x + 7 + 5 x + 3y + 12 5 + 2y + 7x - 4x + 3y - 17

Which is the equation of a line perpendicular to the line with the equation 3x+4y=8
