X < 2 , x > - 2
- 2 < x < 2
- 1 , 0 , 1
the answer is C
Answer:
A = 55
B = 60
Step-by-step explanation:
We know that 55+ b+ other angle = 180 since they make a straight line
The other angle = 65 since they are alternate interior angles
55+ B+ 65 = 180
Combine like terms
120 + B = 180
B = 60
A + B + 65 = 180 interior angles of a triangle must equal 180 degrees
A +60+ 65 =180
Combine like terms
A +125 = 180
A = 55
Using translation concepts, it is found that the function g that reflects f across the x-axis is given by:
![g(x) = -x^3 - 9x^2 + 3x + 1](https://tex.z-dn.net/?f=g%28x%29%20%3D%20-x%5E3%20-%209x%5E2%20%2B%203x%20%2B%201)
<h3>What is a translation?</h3>
- A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
- A reflection across the x-axis means that the function is <u>multiplied by -1</u>.
In this problem, the function is:
![f(x) = x^3 + 9x^2 - 3x - 1](https://tex.z-dn.net/?f=f%28x%29%20%3D%20x%5E3%20%2B%209x%5E2%20-%203x%20-%201)
With the reflection across the x-axis, it is multiplied by -1, and hence:
![g(x) = -x^3 - 9x^2 + 3x + 1](https://tex.z-dn.net/?f=g%28x%29%20%3D%20-x%5E3%20-%209x%5E2%20%2B%203x%20%2B%201)

Answer:
I believe it is associative property of addition or commutative
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Median = The middle number ( in terms of value )
So the first step is usually to put the set of numbers in order from least to greatest but they have already done that for us
That being said all we have to do is find the middle number
In the set, 10, 18, 21, 25, 31, 33, 36
the middle number would be 25
therefore your answer is D
