Answer:By 8(4)P.5, the slope of the line equally inclined to axes is tan(±45  
o
 )=±1. Hence by P+λQ=0,
5λ+3
2λ+4
 =±1
⇒λ=  
3
1
 ,−1. Putting for λ, the two lines are
x−y=0,x+y−2=0.

Answer:
P = 1600 + 60N; $3,340
Step-by-step explanation:
Since we know she gets $1,600 as a base, and $60 <em>each book</em>, we have to add a variable to 60 to show how many books she sells. Your first equation will be P (which is the total) = 1,600 + 60N. Now, we have to replace N with 29. You now have P = 1,600 + 60(29) = 1,600 + 1,740 = $3,340. That's your answer!
