a)-2

b)-1/2

c)1/2

d)2

2)If the area of trianle ANT is 5 square inches, the area of its image A'N'T' under the dilation D would be:

-2

a)5/2 square inches

b) 3 square inches

c) 10 square inches

D) 20 square inches

1)I believe it is A

2)I believe it is C

Also a few other problems,

3) Find the image of (6,-9) under the dilation D negative 1.

4) Find the image of (6,-9) under the dilation D 2/3-

For the above 2 problems:

3)I believe you would just multiply the -1 to 6 and then -9.

4)I believe you would just multiply the 2/3 to the 6 and then to the negative 9.

Apply this to the following problems: A blueprint has a scale of 1 inch=12 feet. Find the actual length represented by each length represented by each length of this blueprint.

5)3/4 inch

6)1 1/2 inches

7)2 1/8 inches

Im not sure how to do those but I think you have to change each of them to like units and multiply, so 3/4 times 12. Im not sure how to do those at all.

Apply this to the following problems: A blueprint has a scale of 1 inch=12 feet. Find the length on the blueprint needed to represent each length.

8)6 feet

9)24 feet

Thanks in advance for any help that anyone could give me.

Thanks again,
