Answer:
x<3 AND x>2
Step-by-step explanation:
First, 4x-4<8. Adding 4 to both sides, 4x<12, and dividing by 4, x<3.
Next, 9x+5>23. Subtracting 5 from both sides, 9x>18, and dividing by 9, x>2.
Therefore, x<3 AND x>2.
Number 1 I think sorry if I am incorrect.
45
You do 30 divided by 2 = 15. then you do 15+30=45, and boom, there is your answer
F(-4). F(x) = 2x^2 - x + 9
