y=  \frac{a}{x-h} +k
\\x=4 \ vertical\ asymptote
\\ Vertical\ asymptote \ can\ be\  found \ from
\\ \\x - h = 0,\ x=h,
\\ \\ so \ h = 4
\\ \\ y=  \frac{a}{x-4} + k= \frac{a+kx-4k}{x-4} 
\\Vertical\ asymptote \ can\ be\ found\ as 
\\ \\  \frac{kx}{x} = k.
\\ We\ know\ that\ vertical\ asymptote\ is\ 2,\ so\ k=2.
\\ \\ y=  \frac{a}{x-4} + 2
\\ \\ We \ need\ to\ find\ a.\ We\ have\ point\ (5,4),\ that\ belongs\ to\ \\this\ function.\ So,
\\ \\ y=  \frac{a}{x-4} + 2
\\ \\4=  \frac{a}{5-4} + 2





4=  \frac{a}{5-4} + 2
\\ \\ 2=  \frac{a}{1} 
\\ \\ a=2
\\ \\ So,\ hyperbola\ has\ formula
\\ \\ y= \frac{2}{x-4} +2

Calculate the total installment price the carrying charges in the number of months needed to save them money at the monthly rate
masha68 [24]

Answer:

  • the total installment is $936
  • the carrying charges are $186
  • the monthly rate to buy the items are  19.23 or 20 months

Step-by-step explanation:

$39 for 24 months comes to ...

$39 × 24 = $936

The "carrying charges" are the difference between the cash price and the installment price:

$936 -750 = $186

 Saving at the rate of $39 per month, it would take ...

  $750/$39 = 19.23 months   about 20 months to save up the cash price.

Often, such savings would come from a once-a-month paycheck, so it would take more than 19 such paychecks to save the required amount.

hope it will help :)
