first one
A is right, it is trsnalated 3 units down
B s wrong
C is wrong because it doesn't go negative
D is wornb ecause it should be 3 down
A
2nd
square both sides
3x≤2x+3
minus 2x
x≤3
also, x can't be negative because squaer root of negative is not allowed
0≤x≤3
C
3rd attachment
note that it can't go negative so max x is 4
min x is -4/3
squre bot sides
4-x≥3x+4
add x both sides
4≥4x+4
minus 4
0≥4x
0≥x
reember it has to be greater than -4/3
-4/3≤x≤0
