$\bf (\stackrel{x_1}{8}~,~\stackrel{y_1}{h})\qquad (\stackrel{x_2}{5}~,~\stackrel{y_2}{-8}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-8-h}{5-8}=6\implies \cfrac{-8-h}{-3}=6 \\\\\\ -8-h=-18\implies -8+18=h\implies 10=h$

Answer:

$894

Step-by-step explanation:

0.06 x 500 x 8^1.25 (-9)= 500+ 403 = $903-9= $894

1.25 = 1/8 of 1 (-9)

1=each power.

8th year = $843.75

9th year = $894

Semi annually you can do the same as 16/1 -17

Answer:

$70 > 55 + t$

Step-by-step explanation:

Given

$Previous\ Time = 1\ hr\ 10\ mins$

$Current\ Time = 55\ mins$

Required

Represent the additional time needed as an inequality

Convert the previous time to minutes

$Previous\ Time = 1\ hr\ 10\ mins$

$Previous\ Time = 1 * 60\ mins + 10\ mins$

$Previous\ Time = 60\ mins + 10\ mins$

$Previous\ Time = 70\ mins$

Let the additional time be t

<em>This means that she needs to run at least t minutes to beat her previous record</em>

<em />

To beat her previous record, the sum of current time and x must be less than her previous time. i.e.

$55 + t < 70$

This can be rewritten as:

$70 > 55 + t$
