Arecipe calls for 2 cups of flour to make 24 cookies. write and solve a proportion to find how much flour is needed to make 54 cookies.
a. 2/24 = x/54; x = 4 1/2 cups
b. 2/54 = x/24; x = 8/9 cup
c. 2/54 = 24/x; x = 27 cups
d. 2/24 = 54/x; x = 648 cups

Let the closed interval [a , b] be the domain of function f. the domain of f(x - 3) is given by (a) the open interval (a , b) (b) the closed interval [a , b] (c) the closed interval [a - 3 , b - 3] (d) the closed interval [a + 3 , b + 3]

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.
