What is the arc measure, in degrees, of AC on circle P below?
70°
104°

My guesses are 104.

Step-by-step explanation:

A flat line is always 180!!

Not sure if it's right tho, please don't come at me!!

we don't have enough info to solve this

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
