Answer:
Not proportional
Step-by-step explanation:
If you just Find the unit rate of each thing, you’ll find that none of them are equal to each other.
Given:
The vertices of a triangle ABC are A(-2,1), B(-1,4) and C(-4,5).
Triangle ABC is reflected over the x‐axis, reflected over the y‐axis, and rotated 180 degrees.
To find:
The point B'.
Solution:
If a figure reflected over x-axis, then


If a figure reflected over y-axis, then



If a figure rotated 180 degrees about the origin, then



So, the coordinate of point B' are (-1,4).
Therefore, the correct option is A.
Hey there!
The word reflected means when something is basically coping everything that you do. So, for example, when I look in a mirror, the mirror would reflect everything that I would do.
So, from looking at the graph above, as we should <em>remember </em>the
![\left[\begin{array}{ccc}\boxed{x-axis}\end{array}\right]](https://tex.z-dn.net/?f=%20%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D%5Cboxed%7Bx-axis%7D%5Cend%7Barray%7D%5Cright%5D%20)
is the

that is
(horizontal) and the

is the

that is
(vertical).
So, from knowing this information of graphs, we now know that
![\left[\begin{array}{ccc}AB\end{array}\right]](https://tex.z-dn.net/?f=%20%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7DAB%5Cend%7Barray%7D%5Cright%5D%20)
are reflecting over the

which is the line that is
(horizontal).
Your correct answer would be
. . .

Hope this helps you!

Answer:
7.1
Step-by-step explanation:
- Find mean
- For each number you subtract the mean and square the result.
- Work out the mean of those squared differences and find square root of that.
- Hope that helped! Let me know if you need further explanation.
The set of all numbers less than or equal to -8 or greater than or equal to 2 is -8 ≥ x ≥ 2. The set is {x∈R|-8 ≥ x ≥ 2}
<h3>The set of numbers</h3>
From the question, we are to write the set of numbers l<u>ess than or equal</u> to -8 or<u> greater than or equal</u> to 2
Let x represent the set of the numbers
If a number is less than or equal to -8
Then,
-8 is greater than or equal to the number
That is,
-8 ≥ x
If a number is greater than or equal to 2
Then,
x ≥ 2
Thus, the set of all the numbers is
-8 ≥ x ≥ 2
Hence, the set of all numbers less than or equal to -8 or greater than or equal to 2 is -8 ≥ x ≥ 2. The set is {x∈R|-8 ≥ x ≥ 2}
