M+4-3m=4+12m alguem pode me dizer qual o resultado ?

Which equation results from adding the equations in this system? x+6y=9 and -x+2y=-15

Factor the expression using gcf 9b+45

M the table below represents a linear function f(x) and the equation represents a function g(x): x f(x)−1 −50 −11 3g(x)g(x) = 2x − 7part a: write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points)part b: which function has a greater y-intercept? justify your answer. (4 points)
