Determine the whether the sum of 7/8 and 4/9 is closest to 0,1,2,or 3

Write numerical coefficient of y² in the expression 2x² - 15xy – 7y²

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.

Lines a and b are parallel. what is the value of x? -5 -10 -35 -55
