B. b ≥ –9.5 or b ≥ 5.5
C. b ≤ –9.5 or b ≤ 5.5
D. b ≤ –9.5 or b ≥ 5.5
Answer:
option (c) is correct.
The given expression all real numbers at most –9.5 or at least 5.5 is written as b ≤ –9.5 or b ≥ 5.5
Step-by-step explanation:
Given expression all real numbers at most –9.5 or at least 5.5
We have to represent the given expression mathematically and choose the correct from given options.
Consider the given expression all real numbers at most –9.5 or at least 5.5
Let the real number be represented by b
then the given expression contain two terms
1) all real numbers at most –9.5
Mathematically written as b ≤ –9.5 .....(1)
2) all real numbers at least 5.5
Mathematically written as b ≥ 5.5 ....(2)
Thus, the given expression all real numbers at most –9.5 or at least 5.5 is written as b ≤ –9.5 or b ≥ 5.5
Thus, option (c) is correct.

A is the answer my folks.
Answer:
f(x + 1) = x² - x
Step-by-step explanation:
f(x) = x² - 3x + 2 when f(x + 1)
f(x + 1) = (x + 1)² - 3(x + 1) + 2
f(x + 1) = (x² + 2x + 1) + (-3x - 3) + 2
f(x + 1) = x² - x + 0
f(x + 1) = x² - x

B.negative one-third
C.3
D.The slope is unidentified
Answer:
The correct option is
Step-by-step explanation:
The parameters given are;
The length of the string = 10 inches
The speed or rate of travel of the wave = c inches per millisecond
The position on the string from the left-most end = x
The time duration of motion of the vibration to reach x= 0.3 milliseconds
The distance covered = Speed × Time = c×0.3
Given that the string is plucked at the middle, with the vibration travelling in both directions, the point after 0.3 millisecond is x where we have;
The location on the string where it is plucked = center of the string = 10/2 = 5 inches
Distance from point of the string being plucked (the center of the string) to the left-most end = 5 inches
Therefore, on the left side of the center of the string we have;
The distance from the location of the vibration x (measured from the left most end) to the center of the string = 5 - x = -(x -5)
On the right side of the center, the distance from x is -(5 - x) = x - 5
Therefore, the the equation that can be used to find the location of the vibration after 0.3 milliseconds is or which gives the correct option as A
