Isometry means lengths are preserved, and hence shapes must remain congruent.
Any dilation, stretching, etc are therefore excluded.
The transformations on the list that are examples of isometry are therefore:
rotation
translation
reflection
2x2-3x-20=0
4-3x-20=0
2-20=-16
-3x-16=0
-3x=16
x= -5.33333
I think i did it right. i hope this helps.
Answer:
<h2>C. 5/9</h2><h2 />
Step-by-step explanation:
10x = 5.5
<u> -x = 0.5</u>
9x = 5
x = 5/9
therefore, the answer is C. 5/9
Answer:
a) 10√2 is correct answer
Since it costs $4 to rent the first movie, and $X for each additional movie, the correct equation is y=4x+4.
The reason it's 4x instead of 5x is because the first movie costs $4, and the remaining 4 movies cost $X each.
