A football team won 10 matches out of the total number of matches the great if their win percentage was 40 then how many matches did they play in all.

i draw it for you in the picture step by step

if you explain the the question more correctly i might be able to answer this better

step-by-step explanation:

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.
