1. 2 4/5v-2/3(4v+1 1/6) 2. 8 - (1/8r - 3 2) 3. 1/7(14x + 7) - 5 you can answer as many as you want and show the work or not, as long as i get an answer i'm okay : )

how long did the flood last

step-by-step explanation:

then i will answer

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.
