Mandy and Pam each made a bowl of punch. Pam used 9 times as much lemonade as Mandy did. If Mandy used 3/4 of a cup of lemonade, how many cups of lemonade did Pam use?

What situation is an example of an observational study

Triangle xyz has vertices x(1,3), y(0,0)

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.
