If h(x) = 6 - X, what is the value of (nºn)(10)?

What is the measure of x? 43° 86° 172° 344°

This is geometry. could anyone ? i can't fail this class. my grade is quite low already.

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.
