if 150 televisions are sold, what is the profit?
profit is the difference between revenue and cost. the
revenue, in dollars, of a company that manufactures
televisions can be modeled by the polynomial 3x2 + 180x.
by the polynomial 3x2 + 180x.
the cost, in dollars, of producing the televisions can be
modeled by 3x2 - 160x + 300. the variable x is the number
of televisions sold.
$2,700
$6,000
$50,700
$51,300

Need solving this second acceleration problem.

Find the value of x for which the lines are parallel.

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
