Answer:The center is (-5,2)
The radius is 5
Step-by-step explanation:
Equation of a circle is:
(x-h)^2+(y-k)^2=r^2
(x+5)^2+(y-2)^2=5^2
Comparing both equations we get :
The center (-5,2)
The radius is 5
Answer:
A)(7,-9)
Step-by-step explanation:
we know x=7
so put it in the equation
y= -2(7)+5
y=-9
we always put the x coordinate first and then the y coordinate so the answer is (7,-9)
10x +4 </ 25 (the </ is a less than or equal to sign)
