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
Step-by-step explanation:
Answer:
8 is the slope
Step-by-step explanation:
Because the amount per 1 thing is the slope
Answer:
y=5
Step-by-step explanation:
I am pretty sure that is the answer but dont rely completely on me
The answer is -3. When you add 5 to both sides to isolate the z variable, the 5 is added to the -8. 5 - 8 = -3.
