In order to solve this system using the substitution method, what would be the first step? {x+2{x+2y=107x−2y=12y=1{x+2y=107x−2 y=120

The description below represents function a and the table represents function b: function a the function is 5 more than 3 times x. function b x y −1 2 0 5 1 8 which statement is correct about the slope and y-intercept of the two functions? (1 point) their slopes are equal but y-intercepts are not equal. their slopes are not equal but y-intercepts are equal. both slopes and y intercepts are equal. neither slopes nor y-intercepts are equal.

25 ! i need asap! ! ill mark brainliest!

Factor this polynomial completely. 12x^2+ x-6
