Question 1710 Based the known slopes of the lines, and on the point data shown in Fig 207, at what points would the lines representing the twobytwo linear system intersect the graph of the equation y = 2 Answer 1710 The graph of the equation y = 2 would appear as a vertical line in Fig 207, parallel to the x axis and running through the point ( 2, 0) To reach this line from the point (2, 3), we can travel in the negative y direction by 4 units along either of our existing lines First, let s move along the line for x = (1/2)y 4 The slope is 1/2 That means if we go 4 units in the negative y direction, we must go 4/2, or 2, units in the negative x direction to stay on the line That will put us at the point ( 2, 5) Now let s move along the line for the equation x = 3y 9 The slope is 3 Therefore, if we go 4 units in the negative y direction, we must go 4 3, or 12, units in the negative x direction to stay on the line That will get us to the point ( 2, 15) 18
Question 181 Here is a set of equations that forms a threebythree linear system: 4x = 8 + 4y + 4z 2y = 5 + x 5z 4z = 13 2x + y 336 Review Questions and Answers
How can we put the first of these equations into the form ax + by + c = d, where a, b, c, and d are constants Answer 181 Here are the steps we can take, one at a time, starting with the original equation: 4x = 8 + 4y + 4z 4x 4y = 8 + 4z 4x 4y 4z = 8 Question 182 How can we put the second equation in Question 181 into the form ax + by + c = d, where a, b, c, and d are constants Answer 182 Here are the steps we can take, one at a time, starting with the original equation: 2y = 5 + x 5z x + 2y = 5 5z x + 2y + 5z = 5 Question 183 How can we put the third equation in Question 181 into the form ax + by + c = d, where a, b, c, and d are constants Answer 183 Here are the steps we can take, one at a time, starting with the original equation: 4z = 13 2x + y 2x + 4z = 13 + y 2x y + 4z = 13 Question 184 Based on the rearrangements in Answers 181 through 183, how can we state the threebythree linear system from Question 181 now What strategies can we use to solve it Answer 184 We can state the system by combining the final equations from Answers 181 through 183, like this: 4x 4y 4z = 8 x + 2y + 5z = 5 2x y + 4z = 13 Part Two 337
We can solve this system in many different ways In Chap 18, we learned to solve systems of this type by getting rid of one variable, resulting in a twobytwo linear system, solving that system, and then substituting back to solve for the variable we eliminated That s the method we ll use here We can get rid of any of the three variables by morphing and adding any two pairs of the threevariable equations Question 185 How can we obtain a twobytwo linear system in x and z from the threebythree system as stated in Answer 184, using the first two equations and then the second two Answer 185 Here are the first two equations from the threebythree linear system as stated in Answer 184: 4x 4y 4z = 8 x + 2y + 5z = 5 We can divide the top equation through by 2 and then add the bottom equation, getting the sum 2x 2y 2z = 4 x + 2y + 5z = 5 x + 3z = 9 That s the first equation in our twobytwo system To get the second equation, let s look at the second two equations from the threebythree system as stated in Answer 184: x + 2y + 5z = 5 2x y + 4z = 13 We can multiply the bottom equation through by 2 and then add it to the top equation, getting x + 2y + 5z = 5 4x 2y + 8z = 26 3x + 13z = 31 Now we have the following twobytwo linear system in the variables x and z : x + 3z = 9 3x + 13z = 31 Question 186
