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)
5y = 4x + 20
- 4x + 5y = 20
Answer:
first one
2m=1 == 2+m-1+m
Step-by-step explanation:
The given expression is:

So, there are two terms in the expression
1)

2) -5
The constant term is -5.
The co-efficient of

is 4.
