Know the order of operations. However, one of the trickiest things about solving an algebra<span> equation as a beginner is knowing where to start. Luckily, there's a specific order for solving these problems: first </span>do<span> any math operations in parentheses, then </span>do<span> exponents, then multiply, then divide, then add, and finally subtract</span>

This is exponential growth which has the form

$c=ar^n,\text{ where c=cases, a=initial value, r=common ratio, n=days}\\ \\ c=1000(1.2^n)\\ \\ \text{The sequence for days 2 through 6 is}\\ \\ (2, 1440),(3, 1728),(4, 2073.6),(5, 2488.32),(6, 2985.984)\\ \\ \text{Since these are people we should round to nearest whole person.}\\ \\ (2,1440),(3,1728),(4,2074),(5,2488),(6,2986)$

What would be the slope intercept form for the inequality 3 x − 2 y > 5 ?

tensa zangetsu [6.8K]

Answer:

y < 3/2x - 5/2 or y < 3/2 x - 2.5

Step-by-step explanation:

3x -2y > 5

Solve for y

3x - 2y > 5 when solving a problem with an inequality sign, rewrite the problem and solve with an equal sign and add the equality at the end.

3x - 2y = 5

-2y = -3x + 5

y = -3/-2x+ 5/-2

y = 3/2x - 2 1/2

Now if you have to use the inequality sign, you will use < because the y term was negative and that will change the direction of the inequality sign.

So y < 3/2x - 5/2 or y < 3/2 x - 2.5

<h3>Hey there! </h3><h3>The word/ phrase "standard deviation" <u>means the measure of how to spread out the numbers are </u></h3><h3>So, </h3><h3> $52,$ $61,$ $31,$ $44,$ $47,$ $45,$ $25,$ $48,$ $47$ standard deviation is/are most likely: $\boxed{10.701765171119}$ ← $\boxed{answer}$ </h3><h3>In order for you to find out the standard deviation of this particular problem (or problems of standard deviation) you had <u>to work out for the mean,</u> meaning to simplify the averages of each and every number, then you would have to<u> subtract your mean and your square for the outcome </u> Nextly, <u>workout your mean for those squared for your differences..</u> Lastly <u>take whatever your square of that number and keep it as your result/ outcome </u></h3><h3>Good luck on your assignment and enjoy your day! </h3><h3>~ $LoveYourselfFirst:)$ </h3>
