Answer:
Reflection across y=0
Step-by-step explanation:
The Y axis splits the octagon in half, so if it was reflected it would be mapped onto itself.
Yes 300 is greater and 30 is less then with rounding
Answer:
x = -2
Step-by-step explanation:
1/3(x - 10) = - 4
1/3x - 10/3 = - 4
1/3x = -4 + 10/3
1/3x = -2/3
x = -2/3 · 3
x = -2
It is C because a straight line is 180 degrees, eliminating A. That being said, the “bigger angle” is 12x-30 because it is obtuse. B and D are both acute, while C is obtuse. You can also find the answer by finding x as in the equation 3x+(12x-30)=180. By simplification, x=14. So, plugging it in, 12(14)-30=138.
The answer is 2 √2.
The problem can be simplified by changing the square roots to look like this:
√(8y/y)
Simplify within the square root and you get this:
√8
Factor √8:
√4 √2
Simplify √4:
2 √2
