Answer:
7
Step-by-step explanation:
f(x)=
If f(24), x=24
24-8=16
=4
4+3=7
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

Answer:
The answer is C; y=x+2
Step-by-step explanation:
y=mx+b (3, 5)
5=1(3)+b
5=3+b
subtract 3 from both sides of the equation
2=b
equation; y=mx+b
y=x+2
Answer: C
Step-by-step explanation: all other statements are true because of CPCTC theorem. Therefore, we can conclude that C is the correct answer
