(geometry) pb is a line segment on a number line. it has endpoints at -2 and 12. what is the coordinate of its midpoint?
pleas explain how to do this step by step!

the answer is 5

Step-by-step explanation:

if you have any questions or a more detailed explanation feel free to ask in the comments.

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.

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
