∠a and ∠b are complementary angles. the measure of ∠a is twice the measure of ∠b. write and equation to represent the complementary angle relationship between ∠a and ∠b. use the equation to find the measure of ∠a and ∠b. show all of your work.

Barney & noblet customers can choose to purchase a membership for $25 per year members receive 10% off all store purchases 1. how much would a member pay per year if he bought $50 worth of items each year? 2. write a slope-intercept equation that expresses how much a member pays per year using x to represent his purchases per year 3. how much would a member have to spend per year to pay off his membership fee?

The roots of the function f(x) = x2 – 2x – 3 are shown. what is the missing number?

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.
