Answer:
Consider triangle ABC with vertices at points A(2,-4), B(4,-4) and C(4,-2).
1. The rotation acts with the rule:
Then:
2. The reflection across the y-axis has a rule:
So,
Triangle A''B''C'' is exactly the same as tiangle from figure 1.
Answer: correct choice is 1.

Step-by-step explanation:
Answer:
x=-7
Step-by-step explanation:
first, subtract 4x from both sides. then you'll get:
-9=3x+12
next subtract 12 from both sides. Then you'll get:
-21=3x
then you divide each side by 3. You get:
x=-7
Area of circle = πr²
= 64π
The cord will subtend a semicircle of diameter 8", radius 4". The area of this semicircle:
1/2 πr²
= 0.5 x 4² x π
= 8π
Area of larger region = area of circle - area of semicircle
= 64π - 8π
= 56π inch²
Raymond bought 9 rolls because you divide 3 and 4 to get 0.75 and multiply it by 12 to get 9 rolls
