The first questions answer is 50.
The second questions answer is 480
The third is 90
The fourth answer is 180
Lastly the last answer is 180 again
The rotational order is the number of times it can rotate upon itself.
This means the shape has 9 sides.
360 /9 = 40 degrees
- Vertex form:

So firstly, put x^2 - 4x into parentheses: 
Next, we need a perfect square inside the parentheses. Divide the x coefficent by 2 then square that result. In this case, -4 ÷ 2 = -2, (-2)²= 4. Add 4 inside the parentheses and then subtract 4 outside the parentheses:

Lastly, factor what's inside the parentheses and <u>your vertex form is
</u>
1. -8 is greater
2. -91 is greater
Answer:
y = (2x + 15)/3
Step-by-step explanation:
3y = 2x + 15
Divide both sides by 3,
3y/3 = 2x/3 + 15/3
Simplify,
y = (2x + 15)/3
