At his college, Jason can take a maximum of 21 hours each semester between elective classes and core classes. Each elective class costs $225 per semester hour and each core class costs $275 per semester hour.
If he cannot spend more than $6,000 each semester on classes, which system of inequalities below can be used to determine
the number of elective classes, e, and the number of core classes, c, he can take each semester?

The triangles are similar. what is the value of x? x=

Ineed i been stuck on this question since yesterday

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.
