Which one you need help on?
X-9 = -5x+ 9
x + 5x = 9 + 9
6x = 18
x = 3
The answer is (4x-5)(5x^2+1)
Correct answer is C.
Line

intersects y-axis at -2 and passes through the point (3,-1).
Line must be dashed, because the inequality sign is ">".
Point (0,0) must lie in the solution set because it satisfies inequality

.
Mult. the 2nd eqn by 6 and then add this "new" equation to the 1st given eqn:
-6x + y = -2
6x -18y = 54
--------------------
-17y = 52, or y = -52/17. Subst. this value of y into either equation to find the value of x.
