Ihave 2 solve the radical inequality and 1 graph question can someone good with math plz me

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

D

A
C
D

Find 2 numbers multiply those 2 numbers the answer will be -30 but if add them together will get 7so 10 and -3 are the two numbers10(-3) = -3010+(-3) = 7(x-3)(x+10) hope this !
