Answer:
The scale factor is 1/2
Step-by-step explanation:
we know that
A dilation is a non rigid transformation that produces similar figures
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
z ---> the scale factor
x ---> the area after dilation
y ---> the original area
we have
substitute
Answer:
A, C, F
Step-by-step explanation:
JK is proportional to PQ, so that would be 8/x. Then, JL is proportional to PR, which would be 10/5. So, the answer is: 8/x = 10/5
Then, C would also be correct as KL is proportional to QR, and JK is proportional to PQ.
Finally, F is correct as JK to KL is proportional to PQ to QR, as JK is proportional to PQ, and KL is proportional to QR.
If I’m not mistaken I think this is what you’re asking for?
Answer:
x <u>></u> -3
Step-by-step explanation:
- 4x - 10 <u><</u> 2
+ 10 <u><</u> + 10
<u>- 4x < 12</u>
-4 -4
x <u>></u> -3
I think the sign flips because the negative sign is w/the X.... If it doesn't, sorry 4 being wrong...
