Please help me with this one.

The border line of the linear inequality 4x + 7y < 5 is dotted true or false?

Which statements about the system are true? check all that apply. y =1/3 x – 4 3y – x = –7 the system has one solution. the system consists of parallel lines. both lines have the same slope. both lines have the same y–intercept. the equations represent the same line. the lines intersect.

Graph the function =gx+2x3 and give its domain and range using interval notation.
