Answer:
Scale Factor (small to large) is 2.8
Step-by-step explanation:
The scale factor is "how many times" it is larger.
If we have an actual quantity be "a" and the enlarged quantity be "b" and we let the scale factor be "k", we can write the equation shown below:
So, we basically mean "what number" (scale factor) should be multiply with the actual value (smaller one) to get the enlarged value (bigger one). From the problem, we can write:
\
Now we find "k", the scale factor:
Hence, the scale factor is 2.8
Hello,
First of all,
C. and D. are both incorrect because they apply translations to ABC; translations will misalign ADE with ABC.
Next,
A. is incorrect because a dilation of 1/2 will place D at (0,3) from its original point of (0,2). Also, the dilation will place E at (6,0) from its original point of (4,0). The triangle ADE would be too small to map ABC.
Finally,
B. Is the correct answer because a dilation of 2 will place D at (0,4)—where B is—and will place E at (8,0), where C is.
Choice B. maps ADE onto ABC
Sorry for that much information, but I think it’s useful. XD
This is my answer/how I did it :
y+5x=17 can also be 5x+y=17
5x+y=17
-y -y
5x=17-y
+17 +17
5x+17=y (answer)
Answer:
<CDG and <CDB are supplementary angles.
