If you use the elimination method to solve the system of equations, 3x - 4y = 9 and 2x 3y = 7, which of the following would be the best method? method i: multiply both sides of the first equation by 2, and multiply both sides of the second equation by 3. then add the two equations. method ii: multiply both sides of the first equation by 3, and multiply both sides of the second equation by 4. then add the two equations.

Does the function satisfy the hypotheses of the mean value theorem on the given interval? f(x) = 4x^2 + 3x + 4, [−1, 1] no, f is continuous on [−1, 1] but not differentiable on (−1, 1). no, f is not continuous on [−1, 1]. yes, f is continuous on [−1, 1] and differentiable on (−1, 1) since polynomials are continuous and differentiable on . there is not enough information to verify if this function satisfies the mean value theorem. yes, it does not matter if f is continuous or differentiable; every function satisfies the mean value theorem.
