Persamaan garis yg melalui titik ptg garis 2x+3y-8=0 dan 3x+y=0 serta sejajar dengan garis 2x+y-7=0 adalah
Answer (3)
The space between them is growing at the rate of (60 + 80) = 140 miles per hour. It will be 252 miles long in 252/140 = 1.8 hours. That's 1 hour 48 minutes.
The two trains will take approximately 1 hour and 48 minutes to be 252 miles apart, traveling at combined speeds of 140 mph. This was calculated by finding their combined speed and then using the distance formula. The time in hours can be converted to minutes for better understanding.

1. Mencari titik potong 2x + 3y - 8 = 0 dan 3x + y = 0Persamaan2x + 3y - 8 = 0 3x + y = 0 → y = -3xNilai x2x + 3y - 8 = 02x + 3(-3x) = 82x - 9x = 8-7x = 8x = -8/7Nilai yy = -3xy = -3(-8/7)y = 24/7Kesimpulanx = -8/7y = 24/7Titik (-8/7, 24/7)2. Persamaan garisGradien 2x + y - 7 = 0m = -a/bm = -2/1m = -2Persamaany - y1 = m(x - x1) y - 24/7 = -2(x - (-8/7))y - 24/7 = -2x - 16/77y - 24 = -14x - 1614x + 7y - 24 + 16 = 014x + 7y - 8 = 03. KesimpulanMaka, persamaan garis yang melalui titik potong garis 2x + 3y - 8 = 0 dan 3x + y = 0 serta sejajar dengan 2x + y - 7 = 0 adalah 14x + 7y - 8 = 0[tex]\boxed{ \red{ \boxed{\pink{\mathcal{M \frak{ ilana} \purple{ \tt01}}}}}} [/tex]
