c, d, a, b.
Step-by-step explanation:
I'm presuming that the original equation is .
First, isolate c. You can do this by subtracting from both sides:
Next, simplify to .
Then, divide both sides by 7:
Finally, simplify to .
Answer:
3
Step-by-step explanation:
<u>1) Find two corresponding lengths between the image and the pre-image</u>
Pre-image (bottom side) = 3 units
Image (bottom side) = 9 units
We can use any corresponding lengths for this step.
<u>2) Divide the length of the side from the image by the length of the side from the pre-image</u>
9 units ÷ 3 units
= 3
Therefore, the scale factor of the dilation is 3.
I hope this helps!
