Which of the following is true about the relationship between the slopes of the lines whose equations are 8x - 9y = 5 and 9x - 8

AlexFokin [52]

The answer is they are reciprocal.

(1) Express both equations in the slope-intercept form: y = mx + b, where m is slope:
<span> 8x - 9y = 5
9y = 8x - 5
y = 8/9x - 5/9
m1 = 8/9

</span><span>9x - 8y = 1
8y = 9x - 1
y = 9/8x - 1/8
m2 = 9/8

So, m1 = 8/9 and m2 = 9/8. They are reciprocal</span>

Dale is 35 years old and planning to retire at age 65. He will invest an average of $155 each month with an average annual retur

weeeeeb [17]

Since he is investing the same amount monthly, we have to apply annuity formula. And it is planned for the future. So that, we'll apply future value annuity formula. The formula is $FV=A[ \frac{(1+ \frac{r}{s})^{Ns} -1 }{r} ]$ , where A is the monthly payment, r is the percentage rate, s is 12 (monthly compound) and N is the time, which is 30. Plugging the numbers into the formula, we write that $FV=155[ \frac{(1+ \frac{0.037}{12} )^{12*30} - 1 }{0.037} ]$ = $8485.450857

How much money would you have in your savings balance after 3 years if you initially invested $900 and had an interest rate of 1

denis-greek [22]

assuming simple interest

$~~~~~~ \textit{Simple Interest Earned Amount} \\\\ A=P(1+rt)\qquad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill & \$900\\ r=rate\to 1\%\to \frac{1}{100}\dotfill &0.01\\ t=years\dotfill &3 \end{cases} \\\\\\ A=900[1+(0.01)(3)]\implies A=900(1.03)\implies A=927$
