Write a system of equations to describe the situation below, solve using substitution, and fill in the blanks. Reba plans to attend the Union County Fair and is trying to decide what would be a better deal. She can pay $30 for unlimited rides, or she can pay $18 for admission plus $2 per ride. If Reba goes on a certain number of rides, the two options wind up costing her the same amount. What is that cost? How many rides is that?

It will cost Reba $ _ for both options if she goes on _ rides.

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.
