When finding the distance between two rational numbers on a number line, does
the order of the numbers you subtract matter?
Explain.

Which ordered pair is a solution of the equation? y + 5 = 2(2+1) choose 1 answer ® only (5,10 ® only (-1,-5) © both (5, 10) and (-1,-5) 0 neither

:24% of students in a class are girls. if there are less than 30 students in this class, how many students are there? how many girls are there?

For problems 29 - 31 the graph of a quadratic function y=ax^2 + bx + c is shown. tell whether the discriminant of ax^2 + bx + c = 0 is positive, negative, or zero.
