If someone were to have 12 friends at the beginning of kindergarten, then losing them one by one each school year, how many friends would they have in 8th grade? this isn't legit, just wondering why

well they would be lonely fr...

Step-by-step explanation:

3 friends

12-8=4-1(kindergarden)=3

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

they would have to work 32 hours.
