326 Review Questions and Answers Painting Quick Response Code In None Using Barcode creation for Software Control to generate, create QR Code image in Software applications. Read QR Code In None Using Barcode reader for Software Control to read, scan read, scan image in Software applications. That s in the form we want! Again from Answer 154, the slopeintercept form of the equation for line QR is y = (5/2)x 1 When we multiply each side by 2, we get 2y = 5x 2 Subtracting 5x from each side, we obtain 5x + 2y = 2 That s in the form we want! Once again referring to Answer 154, the slopeintercept form of the equation for line PR is y=x+2 Subtracting x from each side gives us x + y = 2 That s in the form we want!

How can we put the following twobytwo linear system into a pair of SI equations with y all by itself on the left side of the equals sign 2x y + 8 = 0 and x 3y + 9 = 0 Answer 162 By now, we re good enough at equation manipulation to write down the steps one after another, without having to justify everything For the first original equation, we can do this: 2x y + 8 = 0 y + 8 = 2x y = 2x 8 y = 2x + 8 and for the second original equation, we can do this: x 3y + 9 = 0 3y + 9 = x 3y = x 9 3y = x + 9 y = (1/3)x + 3 Question 163 How can we combine the two equations from Answer 162 to get a firstdegree equation and solve the original system for x Answer 163 We can mix the right sides of the two SI equations together and then solve the resulting firstdegree equation in x by manipulation Here it goes, one step at a time: 328 Review Questions and Answers
2x + 8 = (1/3)x + 3 6x + 24 = x + 9 6x + 15 = x 5x + 15 = 0 5x = 15 x = 3
Question 164 How can we put the twobytwo linear system from Question 162 into a pair of SI equations with x all by itself on the left sides of the equals signs Answer 164 For the first original equation, we can do this: 2x y + 8 = 0 2x + 8 = y 2x = y 8 x = (1/2)y 4 and for the second original equation, we can do this: x 3y + 9 = 0 x + 9 = 3y x = 3y 9 Question 165 How can we combine the two equations from Answer 164 to get a firstdegree equation and solve the original system for y Answer 165 We can mix the right sides of the two SI equations together and then solve the resulting firstdegree equation in y by manipulation, as follows: (1/2)y 4 = 3y 9 y 8 = 6y 18 y + 10 = 6y 10 = 5y y=2 Question 166 How can we be sure the solution we obtained in Answers 163 and 165 is in fact the correct solution to the original twobytwo linear system Part Two 329 Answer 166 The solution we have obtained is x = 3 and y = 2 We must plug these values into both of the original equations to be certain we ve gotten the right solution For the first original equation, we proceed like this: 2x y + 8 = 0 2 ( 3) 2 + 8 = 0 6 2 + 8 = 0 0=0 It checks out! For the second original equation, we do this: x 3y + 9 = 0 3 (3 2) + 9 = 0 3 6 + 9 = 0 0=0 It checks again! Now we know the solution we obtained is correct Question 167 Do you suspect that I concocted the above problem so it would come out with a pair of clean integers for the solution If so, you are right! How can we compose a twobytwo linear system as a test problem (for someone else to solve), and be sure the solution will turn out to be a pair of integers Answer 167 We can choose a point where the graphs of two lines intersect, and assign different slopes to those lines Then we can write down the equations in pointslope form, using the solution point as the reference for both lines Finally, we can convert the pointslope equations to some other form to get the test problem For extra credit, you can try this and then solve the test problem you ve created Question 168 How can we add multiples of the two original equations stated in Question 162 to solve the linear system for x For reference, here are the equations again: 2x y + 8 = 0 x 3y + 9 = 0 Answer 168 We can multiply the first equation through by 3 and then add it to the second equation, getting the sum 6x + 3y 24 = 0 x 3y + 9 = 0 5x 15 = 0
