If you want to cheat, paste the formula in Wolfram Alpha. However, this one is not that difficult. From the fact that x and y are squared you can infer that this is a circle. The 9 reveals that the radius r^2 is 9, so radius is 3.
The (x-2) tells us that the circle is shifted to the right by 2. Likewise, y+1 shifts it down by one. So the center is at (2,-1). If the equation would be x^2 + y^2 = 9, you'd have a circle exactly on the origin.
Hopefully this helps you break down the equation and pick the right picture!
The answer for the equation is c
Answer:
Answer is A! 38 degrees
Step-by-step explanation:
opposite side is the same
Answer: x = 6
1. Subtract “2x” on both sides. This simplifies the equation to x+5=11
2. Subtract “5” on both sides. This simplifies to x=6, which is your answer.
