519 km....ok, lets convert it to centimeters

there are 1000 meters in 1 km, so in 519 km, there are 519 * 1000 meters then.

there are 100 centimeters in 1 meter, so in (519 * 1000) meters, there are then (519 * 1000) * 100 centimeters.

that's how many centimeters Los Angeles is from San Francisco.

now, the slip rate is 2.1 cm per year.

how many times does 2.1 go into (519 * 1000 * 100)?

well, is just (519 * 1000 * 100) / 2.1.

that many years.

5x – 12y – 17 = 0<br> 1*9(x + 2) - (y + 1) + 3 = 0
valentina_108 [34]

Answer: x=\frac{12y+17}{5}

y=\frac{-5x+17}{-12}

x=\frac{y-20}{9}

y=9x+20

Step-by-step explanation:

5x-12y-17=0 (plus 17 from both sides)

5x-12y=17 (plus 12y from both sides)

5x=12y+17 (divide 5 from everything)

x=\frac{12y+17}{5}

5x-12y-17=0 (plus 17 from both sides)

5x-12y=17 (minus 5x from both sides)

-12y=-5x+17 (divide everything by -12)

y=\frac{-5x+17}{-12}

1*9(x+2)-(y+1)+3=0 (distribute 9 to x and to 2) (distribute -1 to y and to 1)

1*9x+18-y-1+3=0 (times 9x by 1)

9x+18-y-1+3=0 (combine like terms)

9x-y+20=0 (minus 20 from both sides)

9x-y=-20 (plus y to both sides)

9x=y-20 (divide 9 from both sides)

x=\frac{y-20}{9}

1*9(x+2)-(y+1)+3=0 (distribute 9 to x and to 2) (distribute -1 to y and to 1)

1*9x+18-y-1+3=0 (times 9x by 1)

9x+18-y-1+3=0 (combine like terms)

9x-y+20=0 (minus 20 from both sides)

9x-y=-20 (minus 9x from both sides)

-y=-9x-20 (divide -1 from everything)

y=9x+20
