Lines can be used to approximate a wide variety of functions; often a function can be described using many lines. If a stock price goes from $10 to $12 from January 1st to January 31, from $12 to $9 from February 1st to February 28th, and from $9 to $15 from March 1st to March 31th is the price change from $10 to $15 a straight line?

Step-by-step explanation:

51^7 - 51^6  =                            => as 51^7 = 51^6 * 51

51^6*51 - 51^6 =                      => factor 51^6 form each terms

51^6(51 - 1)      =                       => as 51 -1 - 50

51^6* 50          =                      => as 50 - 2 * 25

51^6 ( 25*2)

so the original expression is divisible by 25
