Answer:</h3>
B). y = (x -3)(x +1)(x -1)
<h3>
Step-by-step explanation:</h3>
The zeros of the function are -1, 1, and 3, so the factors are (x +1), (x -1), and (x -3).
Selection B is the only choice that has these three factors.
_____
<em>Comment on zeros and factors</em>
When x = a is a zero of a polynomial function, (x -a) is a factor.

Answer: 40
Step-by-step explanation:
Assume Julio's number is x.
The expression would be:
-7 * (x - 15) = -175
x - 15 = -175/-7
x = -175/-7 + 15
x = 40
Answer:
x=37
Step-by-step explanation:
angles inside a triangle add up to 180
add all angles equal to 180
(x+10)+(3x-5)+(x)=180
remove parenthesis, combine like terms
5x-5=180
add 5 both sides
5x=185
divide by 5
x=37
angles: 37, 47, 106
Answer:
it saves 2.5 minutes
Step-by-step explanation:
The expected value of a random variable is the sum of products of possibilities and the probability of each.
Here, you have a probability of 0.9 of saving 5 minutes, and a probability of 0.1 of adding 20 minutes.
__
The expected value of the shortcut is ...
0.9(-5) +0.1(20) = -4.5 +2.0 = -2.5
The shortcut is expected to save 2.5 minutes on average.
_____
<em>Additional comment</em>
The probability of 0.9 comes from the 9 of 10 trips that result in a time saving.
