Answer:(x-3)^2+(y+6)^2=25
Step-by-step explanation:
Center Of The circle is at (3,-6)
Diameter=10
Radius(r)=10/2
Radius(r)=5
a=3
b=-6
Equation of circle=(x-a)^2+(y-b)^2=r^2
Equation of circle=(x-3)^2+(y-(-6))^2=5^2
Equation of circle=(x-3)^2+(y+6)^2=25
Answer:
1
Step-by-step explanation:
Answer:
the answer would be C
Step-by-step explanation:
X + y = 40.....multiply by -4
4x + 6y = 180
-------------------
-4x - 4y = -160 (result of multiplying by -4)
4x + 6y = 180
------------------add
2y = 20
y = 20/2
y = 10 <===
x = 30
Answer:
Step-by-step explanation:
y=mx+b
y-intercept= 1
b=1
point (5,4)
x=5
y=4
y=mx+b
4=m(5)+1
5m=3
m=3/5
rate of change = 3/5
