2x + y < 10 2x - 4y > 8 1) e, f, g, h, j 2) e, f, g 3) a, c, d, k 4) a, e, f

If a and −a are numbers on the number line, which expression must give the distance between them? a) 0 b) a c) |2a| d) |a|

Solve for the equation x. 2x + 22 = 4(x + 3)

Alarger number is double the sum of a smaller number. the larger number is 2 less than 3 times the smaller number. if y represents the larger number and x represents the smaller number, which equations model the situation
