Which step is wrong 3(x+4) 3x+12 3x x=−18 =−18 =−30 =−10 ?

When the solutions to each of the two equations below are graphed in the xy-coordinate plane, the graphs of the solutions intersect at two places. write the y-cordninates of the points of intersection in the boxes below in order from smallest to largest. y=2x y=x^2-3

On a piece of paper, graph y< x+1. then determine which answer matches the graph you drew.

Which one ? is the answer and how to find this answer
