I screenshotted my question.

What is the solution set of the quadratic inequality x^2-5< or equal to 0

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.

Solve for x and y: 217x + 131y = 913; 131x + 217y = 827
