If your asking to select all that apply, The formula is arc length = θ ( r ) {\displaystyle {\text{arc length}}=\theta (r)} , where equals the measurement of the arc's central angle in radians, and r {\displaystyle r} equals the length of the circle's radius. Plug the length of the circle's radius into the formula.ABC,BAD,DCB

If the total bill is $85, and you want to leave a 15% tip, then you can calculate it as follows:
85 * 15%
= 85 * 15/100
= 85 * 0.15
= 12.75
The amount that should be left as a tip is D. $12.75.
I'm guessing the question is "what's the equation"?
When slope and 1 point are known
Since it is a y-intercept then x=0 and the point is
(0,5)
b = y - mx
b = 5 --3 * 0
b = 5
Then we enter the slope and value of "b" into this equation
y = mx + b
y = -3x + 5
