3x^2-12x+1=0
Use formula to solve quadratic eqns
Standard form of quadratic eq is ax^2+bx+c
-b(+,-)sqrtb^2-4ac/2a
Now can u find x?
The sum of a number and its additive inverse is equal to zero. The correct option among all the options that are given in the question is the second option or option "b". If we assume "x" to be a real number, then its additive inverse is "-x". On adding these two, we can see that the result comes to zero.
Well parallel means that it's going to stay next to a line, but never touch the other line. In order for this to happen, the equation of the line needs to have the same slope as the other line's equation. So, keep the slope the same, but you'll need a new y-intercept.
<em>Rewrite the equation:
y=-1/3x+b
Plug in your points (9,-1):
-1=(-1/3)(9)+b
-1=-3+b
Add 3 to both sides:
2=b
Plug b into your new equation:
y=-1/3x+2 *The answer!! :)

The central angles are equal...360/n in this case n=6 so the angles are all 60 degrees...
The arc lengths are the circumference of the pizzas. 4p" and 14p" respectively.
