The point at which a company's costs equal its revenues is the break-even point. C represents the cost, in dollars, of x units of a product and R represents the revenue, in dollars, from the sale of x units. Find the number of units that must be produced and
sold in order to break even. That is find the value of x for which C=R
C = 13x + 28,000 and R = 15x
How many units must be produced and sold in order to break even?

Danny draws a transversal, t, on two parallel lines ab and cd, as shown below: he makes the following table to prove that the alternate interior angles are equal: which is the missing justification? (6 points) corresponding angles formed by a transversal on parallel lines are supplementary. corresponding angles formed by a transversal on parallel lines are congruent. co-interior angles formed by a transversal on parallel lines are congruent. co-exterior angles formed by a transversal on parallel lines are congruent.

The factorization of 8x3 -125 is (2x-5)(jx2 +kx+25)

This is so harddd! solve. 1 + 1 = solve 4 + 4 = solve 3 x 3
