Use substitution to determine which of the following values for y are in the solution set of the inequality: y + 12 > 34 check all that are true. y = 30 y = 20 y = 40 y = 10

Will mark determine whether the conjecture is true or false. give a counterexample for any false conjecture. given: points r, s, and t conjecture: r, s, and t are coplanar. a) false; the points do not have to be in a straight line. b) true c) false; the points to not have to form right angles. d) false; one point may not be between the other two.
