The polygon that when rotated at 180 degrees about it's center may not be carried onto itself is a quadrilateral. The reason being quadrilateral is not regular in the sense that different sides have different measures.
Answer:
A
Step-by-step explanation:
The red function is a transformation. Transformation have the following rules:
- f(x-a) is a units shifted to the right
- f(x+a) is a units shifted to the left
- f(x)+a is a units shifted up
- f(x) -a is a units shifted down
It shifts the red graph 1 unit to the right. This is f(x-1).
Every triangle is 180 degrees, so each other angle should have 20
Answer: (s for small, l for large) s=15.25 kg, l=18.5 kg.
Explanation: We need a system of equation to find the two weights of both boxes.
We can use 4s+8l=209 and 2s+3l=86.
If we multiply the second equation by -2 (for elimination), we will have -4s-6l=-172.
Combing the first equation with this new one gives us 2l=37, where dividing by 2 gives us l=18.5 kg.
We can plug 18.5 into any of the two original equations to find s.
4s+8*18.5=209
4s+148=209
4s=61
s=15.25 kg
