eric can paint a fence twice as his sister can. working together, they can paint a fence in 6 hours. how man hours would it take each of them working alone?

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
