than the elements that make up the air we breathe, so a balloon filled with helium will float in air.

Plastic is a compound of nonmetallic elements, so its
properties make it a popular coating for electric wires to prevent the current from escaping.

Iwill give you ! what is the measure of ∠v ?

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.

What is the point slope form of a line with slope -5 that contains point (2,-1)
