Which system of inequalities has no solution ? I’m not sure

Timed*** there are 8 rows and 8 columns, or 64 squares on a chessboard. suppose you place 1 penny on row 1 column a, 2 pennies on row 1 column b, 4 pennies on row 1 column c, and so on … how many pennies are on each square? a =   b =   c = d =   e =   f = g =   h =

The parabola y = x² - 4 opens: a.) up b.) down c.) right d.) left

Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much
