There is one answer missing from question 3. The point given (40, 120) is NOT part of the solution set. When you plug the values into the inequality, you get 120 < 102. This doesn't make sense, so the point doesn't work for that inequality. Okay, Auger might have made a small mistake on the last question.
He forgot that a positive number divided by a negative number is a negative answer. The answer is (-8, -2). Thanks for pointing it out, Max and Victoria. Study well and remember to make a memory aid tonight. Quiz on distance, midpoints and division points tomorrow. Missing from question 5 is the answer to the question, is point P part of the solution set?
The answer is 'NO,' After you plug point P(0, 1) into the equation 'y < 2.5x +1', you get 1 < 1, which is not true.. |
