The intercept for the second equation is (0, 0).

The lines would queer at (14, 42)/3 Problem-2 ax+y=38 /3 b$175,000x+$200,000y=$7,200,000 /3 cBefore we use elimination, we simplify the second equation by dividing by 25,000: new equation for b): 7x + 8y = 288 in tell apart to eliminate a variable, multiply the first equation by -7: new equation for a): -7x + -7y = -266 Elimination: add the two equations and the xs cancel out: y = 22 x = 38-22 = 16 There are 16 homes with push down device #1, and there are 22 homes with floor plan #2. /3 Problem-3 aAn $80. tap in addition to an hourly allowance is more dearly-won than an hourly charge with no extra fees. tender snuff it away is the better deal. /3 bQuick displace offers the better deal for slight than 4 hours when h < 4.
