Step-by-step explanation:
m(2nr) = r-s
2×n×r×m = r-s
move the r on the right side to the left side
2nrm - r = -s
r ( 2nm - 1 ) = -s
Write the slope intercept form

$ 2000 is invested at 3 % interest and $ 4000 is invested at 8 % interest
<em><u>Solution:</u></em>
Given that, total of $6000 was invested
Let "x" be the amount invested at 3 % interest
Then, (6000 - x) is the amount invested at 8 % interest
Given that,
<em><u>The total yearly interest amounted to $380</u></em>
Then, we can frame a equation as:
<em><u>Solve the above expression for "x"</u></em>
Thus, $ 2000 is invested at 3 % interest
(6000 - x) = 6000 - 2000 = 4000
$ 4000 is invested at 8 % interest

<h3>What is a Stem-and-leaf Plot?</h3>A stem-and-leaf plot is a table which is used to display a set of data in such a way that, on the left we have the "stem" which displays the first digit or digits of a data value.
On the right, we have the 'leaf' which displays the last digit of the data value.
For example, if we are to represent "25" and "26" on a stem-and-leaf plot, we would have: 2 | 5, 6.
Therefore, the stem-and-leaf plot for 29,22,21,6,13,6,17,29,26,9,16,10,25,3,2,23,13,10,7,16,29,30,4,11,7,28,27,22,10 is shown in the image attached below (see attachment).
