Anthony earn 7$ an hour and he wants to buy a new bike that cost 150$ how many hours does he need to earn to buy the bike

To be exact 21.4 hours but I bet u can round it to 22 hours ALSO THAT IS BELOW MINIMUM WAGE

X^2 - 4x +(4/2^2) + y^2 + 8y + (8/2^2) = -4 + (4/2^2) + (8/2^2)(x + 2)^2 + (y + 4)^2 = -4 + 4 + 16your center is (-2, -4) and the radius is the sqrt of -4 + 4 + 16 which is 4
