Answer:
x<3
where x does not exist
(-infinity, 3)
Where x exists
[3, infinity]
Step-by-step explanation:
I'm just going to answer the first one.
Treat it like your solving for x, however the only difference is that it's an inequality.
3x-2 <7
3x< 7+2
3x/3x < 9/3
x<3
Now we know where x does and does not exist.
I'm assuming your teacher wants that, (-infinity, 3) (this is where it does not exist)
[3, infinity]
In case you were wondering square brackets is where it exists and curled is where it doesn't.

Answer:
discriminant=D=0
Step-by-step explanation:
given, 9x^2-18x+9=0...............(1)
equ (1) divided by 9
x^2-2x+1=0
discriminant=D=b^2-4ac
where, b=-2, a=1, c=1
D=(-2)^2-
D=4-4=0
D=0
hence discriminant=D=0 answer
