100 pointsss me guys. im begging you.

Para resolver proporciones necesitas cruzar multiplicar. El error es que ella multiplicó los numeradores y luego los denominadores. Para resolver correctamente deberías multiplicar 3.5 • 12 y 5 • x. Esto daría como resultado 42 = 5x. Entonces dividirías 5 de ambos lados para obtener x = 8.4

Espero que esto ayude <3

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.
