Answer:
B because they are the same angle
You can go full 2π rotate around counterclockwise so the angle wouldn't be negative.
So -π/2 + 2π = -π/2 + 4π/2 = 3π/2
So (4, 3π/2) is the same point as (4, -π/2)
Answer:
B
Step-by-step explanation:
Given
7x - 9 > 2x + 6 ( subtract 2x from both sides )
5x - 9 > 6 ( add 9 to both sides )
5x > 15 ( divide both sides by 3 )
x > 3 → B
2.8. The mean of the problem was 10. After subtracting each number by 10 I added the absolute value of each difference. I divided that sum by 5 and got 2.8
