That is your answer
Answer:
X= - 4
X= - 8
Step-by-step explanation:
-x - 1 +7 =10
-x +6 =10
-x = 10-6
-x = 4
Divide by - 1
X = - 4
4x +7=2x-9
4x-2x =-9 - 7
2x =-16
Divide by 2
X = - 8
Answer:
Option C
Step-by-step explanation:
Standard equation:
r^2 = (x-h)^2 + (y-k)^2
Radius: r
Center: (h,k)
Plug the values in.
r^2 = (x+8)^2 + (y-15)^2
Using distance formula, you conclude that the radius is 17 since the distance from (-8,15) to (0,0) is 17.
r^2 = 289
That means option C is the right answer.
289 = (x+8)^2 + (y-15)^2
