The number of fish in a lake can be modeled by the exponential regression equation y=14.08 x 2.08^x where x represents the year

Four individuals pool money together to start a new business and agree to split the profits equally. n invests $6,000, x invests $2,000, y invests $8,000 and z invests $4,000. if the profits for the first month were $100,000, y receives than if the profits were divided in proportion to how much they invested.

Solve each quadratic equation by factoring and using the zero product property. 10x + 6 = -2x^2 -2
