The problem ask to calculate the slope of the line tangent to a circle O at point A if the radius of the circle is 2.5. So based on the problem the tangent line formed a right angle so it means that the slope is also 2.5 and the answer is letter B. 2.5
If you can send an image of the beginning of the question, I’d be glad to help. You didn’t show enough info for me to get an answer
If you want to solve the equation

for C, you can work like this: subtract P from both sides:

Add C to both sides:

C
work:
75 is equal to 2x+15
75-15 = 60
60/2 = 30
x=30
Hello!
4 (x-12) ^ 1/3 = -16
Step 1. Simplify each side of the equation, 4/
3x + −16 = −16 and 4
/3
x −16 = −16
Step 2. Add 16 to both sides, 4
/3
x − 16 + 16 = −16 + 16
Step 3: Multiply both sides by 3/4, (
3/4)*(4/3x)=(3/4)*(0)
Final Answer: x= 0
Hope I could help! :)
