A baker is making cakes. • She starts with 48 eggs.
• She makes 10 cakes.
• She has 18 eggs left over.
Which equation can be used to find the number of eggs, x, the baker uses in
Each cake?

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
