9x^2 + 6x = 1
Factor out 3x
3x (3x +2)=1
Use the zero product property
3x=1
3x+2 = 1
X= +1/3 and -1/3
0.13 0.19 0.3 and 0.31 just in case you didnt know 0.3 =.030
I think the correct decision to make is to accept the guaranteed award of $160000 because the probability of choosing the briefcase containing 500,000 dollars is very low. Chances are you would be able to choose the cases with lower value than the guaranteed award. Hope this helps.
As the equation is already in <em>y</em>=<em>mx</em>+<em>b</em>, all we need to do is use the equation to draw out a graph (or in this case, match with an already existing graph) using the y-intercept and slope. Since the y-intercept is 5, we can eliminate graphs C and D from our answers. We know the slope is -4, which means that our rise over run is -4 over 1. That would mean, to get from one point to the next, you go down 4 spaces and to the right one. This means the correct answer is graph B.
