The above information is from your computer : be sure it is correct. To receive grade credit in Prof McFarland's classes, you must submit this quiz before an assigned date. 
[1]  Complete the system of equations (below) so that the system
has exactly one solution, namely (1,2) ; that is, x = 1 and y = 2. There are many correct answers. Hint : Guess, and then replace x by 1, and y by 2, and check and revise your guess.

(a) The above system has no solution (1 pt if true) (b) The above system has more than one solution (1 pt if true) (c) The above system has one solution (½ pt if true), namely x = and y = (½ pt if true) 
[3]  For the system of equations in the box below, check the statement which is true, and if there is only one solution, enter it?  


(a) The above system has no solution (1 pt if true) (b) The above system has more than one solution (1 pt if true) (c) The above system has one solution (½ pt if true), namely x = and y = (½ pt if true)

[6]  For the system of equations in the box below, check the statement which is true, and if there is only one solution, enter it?  


(a) The above system has no solution (1 pt if true) (b) The above system has more than one solution (1 pt if true) (c) The above system has one solution (½ pt if true), namely x = , y = , and z = (½ pt if true) 
[7]  Read the problem in the box below. You must answer part (a) correctly to get credit for part (b)  


(a) In answering the above question by algebra, how should we define variables x and y ? (for ½ pt)  
(a) Let x = Romulans and let y = Webbans (b) Let x and y = the number of hands in the crew (c) Let x and y = the size of the crew (d) Let x and y = how many aliens of each species which must be chosen (e) Let x = the number of Romulans and let y = the number of Webbans in the crew 

(b)Translate the underlined words in the box above (for ½ pt) : 

[8]  Read the problem in the box below. You must answer part (a) correctly to get credit for part (b)  


(a) In answering the above question by algebra, how should we define variables x and y ? (for ½ pt)  
(a) Let x , y and z = the number of dinosaurs in Jurassic Park (b) Let x = the number of TRexes, y = the number of Velociraptors, and z = the number of Minisaurs in the Park (c) Let x = TRexes, let y = Velociraptors, and let z = minisaurs (d) Let x , y and z = the number of humans gobbled today (e) Let x , y and z = how many dinosaurs of each species there are in Jurassic Park 

(b)Translate the underlined words in the box above (for ½ pt) : 

[9]  The problem in the box below is the same as in problem [8] above, but different words are underlined. You must answer question [8a] correctly to get credit for question [9] here.
