Answer:
Compare x^2 +y^2-8x-6y=75 with the general circle equation x^2+y^2 -2ax-2by+c=0
-2a =-8 And -2b=-6
a=4 b=3
c=-75
To find the radius use the equation
r^2=a^2+b^2-c
r^2=4^2+ 3^2-(-75)
r^2=25+75=100
r=10(radius is always positive)
Hence the center is (4,3) and radius 10

VW = VC + CW
61 = z + 13 + z + 8 = 2z + 21
2z = 61 - 21 = 40
z = 40/2 = 20
z = 20.
Answer:
The answer is perpendicular
Step-by-step explanation:
convert the two equations into slope-intercept form
y=7/5x - 1
y=6/5x -1
Then, put it in the graph and you'll get lines intersecting at the same point which is the y-intercept.
