Hello
<span>D. 2 imaginary roots (complex conjugates)</span>
To solve the inequality, you need to isolate/get x by itself:
171 > -6x Divide -6 on both sides [dividing/multiplying a negative number on
-28.5 < x [dividing/multiplying a negative number in an inequality causes the sign (<, >, ≤, ≥) to flip]
-28.5 < x [x is a number greater than -28.5]
So your graph should have an open circle at -28.5 (the first small line next to -28), and the arrow pointing to the right since x is greater than -28.5 (increasing) The 1st option is your answer
[use the o---> and put it at -28.5]
Ok ok I know you hate links but this is the only way to show you the answer.

Answer:
84
Step-by-step explanation:
f(x) = 3x^2 + 2x – 1
Let x=5
f(5) = 3(5)^2+2(5) -1
= 3*25 +10-1
= 75+10 -1
= 85 -1
Y=2x+2 easy
The slop=2/1
Y-int= (0,2)
