Factor the expression 10y+6

2(5y+3)

Step-by-step explanation:

10y+6

Factor out 2

2*5y + 2*3

2(5y+3)

You have three, each very interesting, questions.1. the intuitive answer of giving priority to the card with the higher apr (credit card 2, with apr=24.15%) is correct.   the credit limit does not affect the choice.   for the same payment on the same day, the reduction in the balance will be more substantial on credit card 2 that that of credit card 1.since every day counts in the  outstanding balance, pay off as soon as possible, count the days.2. for any investment p, at 2% apr,a. if compounded monthly, time to double, t years, is given byp(1+0.02/12)^(12*t) = 2ptake log on both sides after cancelling p12t(log(1+0.02/12) = log(2)t=(log(2)/12)/log(1+0.02/12)=34.686 yearsb. if compounded yearly, proceeding as in part a,p(1.02)^t=2pt=log(2)/log(1.02)=35.003 yearsc. using the rule of 70, time it takes to doublet=70/2=35.000 years.3. $7300 investment at 5% apy compounded daily.   need value of investment after two days.5% apy means the actual yield after a year is 5%, which means that the daily interest, i, is given byp(1+i)^365 = 1.05ptake log on both sides and solving for ilog(1+i)=log(1.05)/365i=e^(log(1.05)/365)-1     [ using natural log, will work with any log ]=0.000133680617113(check:   1.000133680617113^365=1.05, ok)value of investment after one day=7300*1.000133680617113=$7300.9759value of investment after two days   (using previous day value as p because interest is compounded daily)=$7300.9759*1.000133680617113=7301.95   (to the nearest cent)
