1. 1) Simplify the following expression: 5b - 5 - 12b - 7​
Elodia [21]

Answer:

17b - 2

Step-by-step explanation:

5b - 5 - 12b - 7

Say bye to the 12b, and add 12 to it and the 5.

5b + 12 = 17b

17b - 5 - 7

Add 5 to the 5 and the -7.

-7 + 5 = -2.

Now you have 17b - 2. You can’t go farther, so there’s your answer.

Step-by-step explanation:

Dilations preserve angle measures, regardless of the scale factor. Therefore, the angle measures of the image will be the same of that of the pre-image, so our answer is still 45°, 55°, and 80°. Hope this helps!
