-x + 3y = -12 in slope intercept form. please show step by step. thanks :)

y=x/3 - 4

Step-by-step explanation:

add x to get x to the other side

3y= x-12

divide by 3 on both sides to get y by itself y= x/3 - 4 is simplest form

slope intercept form is y=mx+b

add x to both sides : 3y=x-12

divide by 3 on both sides : y=(1/3)x-4

nnnd i put both equations in desmos n they r the same :)

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.
