which of these strategies would eliminate a variable in the system of equations?

2x + 8y = -3

3x + 6y = -4

a: multiply the top equation by 3, multiply the bottom equation by -2, then add the equations.

b: multiply the top equation by 3, multiply the bottom equation by 4, then subtract the bottom equation from the top equation.

c: multiply the top equation by 4, multiply the bottom equation by 3, then add the equations.

In trapezoid klmn, kj=19.2 and jm=22.5. identify ln.

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.
