Elimination was used to solve a system of equations.
One of the intermediate steps led to the equation 9x = 27
Which of the following systems could have led to this equation?
10x - y = 15
x + y =
– 12
9x + 2y = 21
– 9x – 2y = 21
7x – 2y = 15
x + y = 6

List the sides of δrst in ascending order (shortest to longest) if: m∠r =x+28°, m∠s = 2x+16°, and m∠t = x+12

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.
