Question 1128650: The expense, in dollars, to manufacture a asks of 100% Organic Guru Energy drink is , .
The price-demand function, in dollars per ask, is , .
Solve k(a)=0 and interpret.
Solve p(a)=0 and interpret.
(Please notice the comma between k(a) and the inequality, alongside p(a) and the inequality. The problem calls to interpret, I don't think that really means anything... This is a 'basic college algebra' class problem, not so basic for me though)

Question 1129923: Use any method to solve the nonlinear system. (If there is no solution, enter NO SOLUTION.)
−x^2 + y = 8
8y= −x
Could someone assist in explaining how to to correctly solve the equation as my previous answer was wrong. Previously I got: (x, y)= (-1/6 + i / 16) , (1/ 128 -i / 128).

Question 1129997: Could someone assist in explaining how to correctly solve the question. My previous answer was -40-x-3z/2.
Solve the system by Gaussian elimination. (If there is no solution, enter NO SOLUTION. If there are an infinite number of solutions, enter a general solution in terms of one of the variables.)
0.1x − 0.2y + 0.3z = 4
0.5x − 0.1y + 0.4z = 16
0.7x − 0.2y + 0.3z = 16
