5x - 9 > x*10^4
5x - 9 > x * 10000 I hope I'm reading the question correctly.
5x > 10000 x + 9
x > 10000/5 x + 9/5
x > 2000x + 1.8
0 > 1999x + 1.8
- 1.8 > 1999x
- 1.8 / 1999 > x
- 0.0009004 > x

Step-by-step explanation:
Answer:
(1,0)
(5,24)
(-2,3)
Step-by-step explanation:
So we want y=x^2-1 per point.
Let's check them.
(0,1)? Plug in 0 for x and see what y is:
y=0^2-1
y=0-1
y=-1 which is not 1.
(1,0)? Plug in 1 for x and see what y is:
y=1^2-1
y=1-1
y=0 which is what we have for y.
(3,5)? Plug in 3 for x and see what y is:
y=3^2-1
y=9-1
y=8 which is not 5.
(5,24)? Plug in 5 for x and see what y is:
y=5^2-1
y=25-1
y=24 which is what we have for y.
(-2,3)? Plug in -2 for x and see what y is:
y=(-2)^2-1
y=4-1
y=3 which is what y is.
(-4,-17)? Plug in -4 for x and see what y is:
y=(-4)^2-1
y=16-1
y=15 which is not -17.
