Answer:

x = -1

Step-by-step explanation:

Isolate the variable by adding 7 on both sides. 5x-7+7 is 5x, and -12+7 is -5. Then, you get the equation 5x = -5. You have to then divide by 5 on both sides. 5x/5 is x and -5/5 is -1. You would then get that x = -1.

Answer:

Radius: 4

Center: (-5,4)

Step-by-step explanation:

To find the radius, you take the square root of what the equation is equal to (in this case that is 16)

To find the center, you set what is in the parenthesis equal to 0 so:

x+5=0 becomes x=-5

y-4=0 becomes y=4
