2.5x + 11 = 50 can you give me the answer plz HELP

Will give brainliest what is the value of x? enter your answer in the box.

If a || b and b | y, then ? a) x || y. b) x | a. c) a | y. d) a || y.

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.
