You can rewrite your function as
This implies that
Now, we have 
, so it counts as a solution.
On the other hand, depending on the coefficient a, b and c, the cubic equation
can have either one or three solutions.
So, we have the solution x=0, and then one or three solutions coming from the cubic part. The equation as a whole thus have either two or four solutions, depending on the coefficients.

Answer:
0.0001
Step-by-step explanation:
The computation of the probability of experiencing such a drop in water pressure is shown below:
Given that
mean = 519,645 gallons
Standard deviation = 71,564 gallons
Now the probability is
= 1 - p (x - mean ÷ standard deviation < 782,238 - 519,645 ÷ 71,564)
= 1 - p(z<3.67)
= 1 - 0.9999
= 0.0001
Answer:
101/140
Step-by-step explanation:
<u>Solving in steps:</u>
- -6/15 * 4/7 - (-7)/20 * 4/7 + 3/4 =
- - 2/5 * 4/7 + 7/20 * 4/7 + 3/4 =
- - 8/35 + 7/35 + 3/4 =
- -1/35 + 3*35/4*35 =
- -4/140 + 105/140 =
- 101/140
