If you convert all of the fractions to decimals.......
2/8=,25 1/8=.125 2/4=.5 2/6=.333333
So in this case 2/4 has the greatest value....
So for this, we will have to find the zeros (x-intercepts) of the equation. In this case, we will be using the quadratic formula, which is
(a = x^2 coefficient, b = x coefficient, c = constant). Using our info, our equation is such: 
Firstly, solve the multiplications and the exponents: 
Next, do the addition: 
Next, plug in the equations into the calculator and your answer will be: 
Since we can't have negative time in this situation, it can't be -0.41 seconds. Which means that the object is visible for about 0.60 seconds, or C.
It using the slope form which is (y=mx+b), in your case -3 is the m or slope and 2 is b or the y-intersect.
Answer:
1 in 128
I know if you flip a coin 7 times, the odds of getting 7 heads in a row is 1 in 27 or 1 in 128.
