.) Paco and Ping went shopping for erasers, e, and markers, m. Paco bought 5 erasers and 7 markers for $4.05. Ping bought 10 erasers and 3 markers for $3.15. Their purchases can be modeled by the system of equations. *Solve the system of equations for e and m.
*Show your work.

Explain what each numerical solution represents in the context of this word problem.

Tcan be concluded that % of the seniors would prefer to see more candid pictures in this year's edition of the yearbook.

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.

Which statement explains how you could use coordinate geometry to prove the opposite sides of a quadrilateral are congruent? a. use the slope formula to prove the slopes of the opposite sides are the same. b. use the slope formula to prove the slopes of the opposite sides are opposite reciprocals. c. use the distance formula to prove the lengths of the opposite sides are the same. d. use the distance formula to prove the midpoints of the opposite sides are the same.
