Geographers use negative numbers to represent points below sea level and positive numbers to represent points
above sea level.
How would geographers represent a point 7 1/4 meters
above sea level?

Which of the following quartic functions has x = –1 and x = –2 as its only two real zeroes?

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 result of adding the system of equations? 2x+y=4 3x-y=6
