2) Solve the quadratic inequality. Express your answer in interval notation.
(x - 1)( x + 5) < 0

3) Find the slope of the line 3x + 4y = 11.

4) Find the vertex of the parabola f(x) = 4x2 - 32x + 63

5) Solve the quadratic inequality. Express your answer in interval notation.

7) The point at which a company's costs equals its revenue is the break-even. C represents cost, in dollars, of x units of a product. R represents the revenue, in dollars, for the sale of x units. Find the number of units that must be produced and sold in order to break even.
C = 15x + 12,000
R = 18x - 6000

8) In economics, functions that involve revenue, cost and profit are used. Suppose R(x) and C(x) denote the total revenue and the total cost, respectively, of producing a new high-tech widget. The difference P(x) = R(x) - C(x) represents the total profit for producing x widgets. Given R(x) = 60x -
0.4 x2 and C(x) = 3x + 13, find the equation for P(x).
