The expected profit at various selling prices for a new camera can be modeled using the regression equation y = -1.03x2 + 634.56x - 48,587.60. To the nearest thousand dollars, what is the predicted profit when the selling
price is set at $206?

Solve the system of equations. y= 2x y= x^2 - 15

Cody started biking to the park traveling 15 mph, after some time the bike got a flat so cody walked the rest of the way, traveling 4 mph. if the total trip to the park took 6 hours and it was 46 miles away, how long did cody travel at each speed? solve using rate times time= distance
