The function h is defined by h(x) = −50 ÷ x − b, where b is a constant. Find b, if the value of h at x = 1/4 is equal to −200.

When x = 3 and y = 5, by how much does the value of 3x2 – 2y exceed the value of 2x2 – 3y ?

What is always true when two whole numbers are subtracted?

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.
