How many solutions will the following system of equations have? '2x+y=4' '2x+y=8'

Subtracting one equation from the other eliminates both variables and results in a false statement:

(2x + y) - (2x + y) = 4 - 8

0 = -4

So there is no solution to this system.

40% off the regular price is the correct answer.

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.
