F(1) = 1^3 + 3(1)^1 - 3 - 1 = 1 + 3 - 3 - 1 = 0
so one zero is x = 1, and x-1 is a factor
dividing f(x) by x - 1 gives x^2 + 4x + 1
x = [-4 +/- sqrt (16 - 4)] / 2
x = -0.27, -3.73
zeroes are 1 , -0.27 and -3.73 Answer
3(6x-8)-(-4x-7)
18x-24+4x+7

The correct answer is: [C]: " inverse variation; xy = 40 " .
__________________________________________________
Explanation:
______________________________________________
Examine the table given, and plug in the value:
_______________________________________
In the equation for Answer choice: [C]: " xy = 40 ".
When x = 1 , y = 40.
xy = 40 ; 1*40 = 40. Yes.
When x = 2, y = 20.
xy = 40; 2*20 = 40. Yes.
When x = 5, y = 40.
xy = 40. 8* 5 = 40. Yes.
When x = 10, y = 4.
xy = 40. 10*4 = 40. Yes.
_______________________________________
So the equation makes sense ;
"inverse variation; xy = 40".
________________________________________
since; "xy = 40" ; which is "answer choice: [C]".
________________________________________
We know that the other choices do NOT make sense; if we plug in any of the corresponding x and y values for any of the equations provided in any of the other answer choices, the equations will not equal, and as such, the answer choices are incorrect.

Set y1=x+30 and y2=x^2, plugged those into the distance formula assuming x=a<span>,
</span><span>
d=rad(<span>(y2−y1<span>)^2)
</span></span></span><span>d(x)=x^2−x−30
</span>All you have to do is to maximize the given quadratic function. I hope that this is the answer that you were looking for and it has helped you.
