Graph 14x+34y=1 pretty please with a cherry on top!Also thank-you
Svetlanka [38]
To make it much easier, it should be converted to the slope-intercept form
 y = mx + b

To do so, 14x + 34y = 1 turns to:
34y = -14x + 1

Divide both sides by 34:
\frac{34y}{34} =  \frac{-14}{34} x +  \frac{1}{34}
Simplified:
y = \frac{-7}{17} x + \frac{1}{34}

Answer: y = -\frac{7}{17} x + \frac{1}{34}
Here is the graph:

Al and Bill each have two bullets. They fire alternately at a glass bottle. Al has hitting probability 1/3 and Bill 1/4. What is
enot [183]
P(Al hits bottle first time) = 1/3
P(Al misses the first shot but hits on his second shot) =  
P( Al misses and bill misses and Al hits) = 2/3 * 3/4 * 1/3 = 1/6

So required probability = 1/3 + 1/6 =  1/2
