<span>You take the probability of success (and the revenue generated by it) and the probability of failure (and the cost associated with trying it) and get an expected value:
aP(a) + bP(b)
I hope my answer has come to your help. God bless and have a nice day ahead!

(x - 4)/(x + 4)
Step-by-step explanation:

<em>Note :</em>
- a² - b² = (a + b)(a - b)
- (a + b)² = a² + 2ab + b²
The line has a slope of -6 and a y intercept of 7.
The linear equation is given by:
y = mx + b;
where m is the slope of the line, b is the y intercept, y, x are variables.
The equation of the line passing through the points (6.-29) and (-4,31) is:

Hence the line has a slope of -6 and a y intercept of 7.
