A small company produces both doll houses and sets of doll furniture. The doll houses take 3 hours of labor to produce, and the furniture sets take 8 hours. The labor available is limited to 400 hours per week, and the total production capacity is 100 items per week. Existing orders require that at least 20 doll houses and 10 sets of furniture be produced per week. Write a system of inequalities representing this situation, where x is the number of doll houses and y is the number of furniture sets.

A water balloon is catapulted into the air from the top of a building. The height h(t), in meters, of a balloon after t seconds is h(t) = -5t(exponent 2) + 30t + 10. When will the balloon reach a height of 30m?

h(t) = 30
30 = -5t(exponent 2) + 30t + 10
30 = -5(t(exponent 2) - 6t -2)
I'm stuck here.
normally we'd find two numbers that add to the middle number (-6) and multiply to the last number (-2).
Help pleaseeeeee?
