A water tank holds 800 gallons but is leaking at a rate of 5 gallons per week. A second water tank holds 1,000 gallons but is leaking at a rate of 9 gallons per week. After how many weeks will the amount of water in the two tanks be the same? The amount of water in the two tanks will be the same in
weeks.

answer: 1, 3 and 5 are correct

step-by-step explanation:

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.
