A student proposed the following method of sketching the solution to a system of two inequalities. “First, I shade the region of points that satisfies the first inequality. Then, I shade the region of points that satisfy the second inequality. The solution consists of all points that have been shaded.” Do you agree? Explain. Support your answer using the system:
5x3y>1 and 3x+4y<=18

Best ResponseYou've already chosen the best response.1If it's a system of inequalities, that means that both inequalities must be satisfied. And the problem has you shading the areas that satisfy one or the other, but not necessarily both. So no, that's not a valid method. The actual region that satisfied the inequality is the bit that gets shaded twice.

Best ResponseYou've already chosen the best response.0which of these factors is a physical obstcale to communication; noise, race, and 2 others that were pointless. the correct answer out of the book was 'noise'; but the quiz marked it wrong and said 'race' lol
