What is the center and radius of the circle that has the equation (x + 7)^2 + (y - 4)^2 ? explain.

(-7, 4) and 7

Step-by-step explanation:

The standard equation of a circle is expressed as (x - a)^2  + (y - b )^2 = r^2

Where the center is the point (a, b) and the radius is r

Note: simply inserting the variables and playing around with your signs gives you the value for (a and b)

The square root of the radius gives you the value for r

hi, i am not sure about this one but i think its d,

hope this !
