@waterineyes plz help me

You could test each "solution" For example, the starting problem is -7x ≥ 56 it's easy to see if x=0 "works". Replace x with 0 and do -7 * 0 you get 0 now see if this is true: 0 >= 56 is 0 bigger than 56? NO so any choice that has 0 as part of its answer is wrong.

can you rule out any of the choices, knowing x=0 is *not* part of the answer?
