Using the following equation, find the center and radius of the circle.

x^2 + 4x + y^2 − 6y = −4
step 1: (original equation) x^2 + 4x + y^2 − 6y = −4
step 2: (group the like terms)
step 3: (complete the quadratics)
step 4: (simplify the equation)
step 5: (factor each quadratic)
step 6: (identify the center and radius)

can someone complete these steps in order

You paid 28.00 for 8 gallons of gasoline. how much would you pay for 15 gallons of gasoline?

On traditional maps, earth is represented in a flat plane, or by euclidean geometry. however, a globe is a more accurate model that comes from elliptical geometry. how does a globe represent the fact that there are no parallel lines in elliptical geometry? the equator is not parallel to any other latitudinal lines. the north and south poles are never connected by a geodesic. the geodesics connecting the north and south poles never intersect. the geodesics connecting the north and south poles intersect at both of the poles.

Use the quadratic function to predict f(x) if x equals 8. f(x) = 25x2 − 28x + 585
