Answer:
Step-by-step explanation:
The center of the circle whose diameter has endpoints (18, -13) and (4, -3) will be the midpoint of the coordinates.
The ormua for calculating mid point is expressed as;
M(X,Y) ={(x21+x2/2, y1+y2/2}
X= x1+x2/2
Y = y1+y2/2
From the coordinates
x1 = 18 x2 = 4
X= 18+4/2
X = 22/2
X = 11
y1= -13, y2= -3
Y = -3-13/2
Y = -16/2
Y = -8
Hence the required centre will be at (11,-8)
I’m not sure but maybe true
3x-x=10+2
3x-1x=12
2x=12
2÷2. & 12÷2 =6
x=6

Answer:
10/14
Step-by-step explanation:
substitute x in equation 2
y= 2(10) -6
y= 20 - 6
y= 14
substitute y in equation 2
14 = 2x - 6
-2x= -6-14
-2x= -20
divide both sides by -2
-20/-2
x= 10
y= 14, x= 10
