To "break even" means that the costs are equal to the money made, so profit would have to be 0. Therefore, we can rewrite the equation to be
0 = x3 -4x2 +5x -20
From here, all you have to do is factor to be able to solve for the values of x
First, since the first two numbers both have an x2, we can factor that out
x2(x-4) + 5x -20 = 0
The next two can factor out a 5
x2(x-4) + 5(x-4) =0
Since both of these terms share an (x-4), they can be factored to become:
(x-4) (x2 +5) = 0
So now we just solve for x, and get x = 4, and +- (sqrt) 5i
Since 4 is the only answer present in the options (and since 5i is a non-real number), the answer would be 4

Answer:
Step-by-step explanation:
Okay, so we will be using the formula y1-y2/x1-x2:
7--8/3-3=15/0
Now, we can't divide by zero so we can just say the slope of the line is 0
The equation that you must use is y=15x+15
so x would be 1,2,3,4,5 and y would be 30,45,60,75,90
Answer:
N = 15 ; P = 0.3
Step-by-step explanation:
According to the question, the data provided in the question is as follows
The percentage of parolees from prison return to prison = 30%
Number of years = 3 years
Number of prisoners released from a Texas prision is 15
Based on the above information, the value of the parameters for the binomial random variable X is
N = 15 = number of prisoners
And, the P = Percentage = 30% = 0.3
