Juan solved the system of linear equations 8x - 3y = -1
and
-5x+2y = 1

a. First, he multiplied the equation
8x - 3y = -1
by 2 to get

b. Next, he multiplied the equation
-5x+2y = 1
by 3 to get

c. Then he added the two resulting equations together to get

d. Finally, he substituted the result into one of the original equations and solved

Last month, a 770 g box of cereal was sold at a grocery store for $3.10. however, this month, the cereal manufacturer launched the same cereal in a 640 g box, which is being sold at $2.50. what is the percent change in the unit price?

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.
