Hi there!
Triangle OBC is a right triangle. This is because where the radius and the tangent meet creates a right angle. A right angle is created due to the theorem that states that a radius is perpendicular to its tangent.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
It would take four days because there is eight pints in a gallon
You could add the time it takes them individually together and divide by 2. That would give you the average, which is 1 hour.
Answer:
Option B: Only (-2, 9)
Step-by-step explanation:
Given the linear equation, y = -2x + 5:
We'll plug in the given options to see which of the ordered pairs will satisfy the equation:
Substitute option A: (2, -9) into the equation:
y = -2x + 5
-9 = -2(2) + 5
-9 = -4 + 5
-9 = 1 (False statement). Therefore, (2, -9) is not a solution.
Substitute option B: (-2, 9) into the equation:
y = -2x + 5
9 = -2(-2) + 5
9 = 4 + 5
9 = 9 (True statement). Therefore, the ordered pair, (-2, 9) is a solution.
The other two options are irrelevant at this point since we've proven that option B is the correct answer.

I believe the answer to your question would be x = -y + 2
