Which answer is the correct restriction on the domain? x-7/x+4 ÷ x/x+3 a. x=/7,0 b. x=/7,-3 c. x=/-4,0 d. x=/-4,-3 plz

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.
