Find the center and radius of the circle.

Please i need helppp

...

Step-by-step explanation:

di = 2.5 -( - 1.5) = 4

radius = di/2 = 2

c(x, y) =( - 0.5 , 2.5-0.5) =(-0.5 , 0.5)

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
