Enrique has $50 in his lunch account and spends $5 per day from the account. maya has $46 in her lunch account and spends $4 per day from the account. which equations model the situation? 50 – 5x = y and 46 – 4x = y 5x + 50 = y and 4x + 46 = y 5x – 50 = y and 4x – 46 = y 5 – 50x = y and 4 – 46x = y

1/3(x-10)=-4 solve for x with steps

Find the area of the triangle formed by the origin and the points of intersection of parabolas y=−3x^2+20 and y=x^2−16.

Ascientist places 24 cells in a petri dish. she knows the cells grow at an exponential rate, doubling in number every hour. how long will it take (in hours) for there to be 1100 cells in the dish? time to 1100 cells: 5.51832530 hours how long will it take to reach 110 cells? time to 110 cells : 2.1963972 hours what is the average rate of change in the number of cells between 9 hours and 11 hours? average rate of change: cells per hour what is the instantaneous rate of change after 7 hours? instantaneous rate of change: cells per hour note: you can earn partial credit on this problem.
