From Plato
30e-0.12t less than or equal to M
40e-0.18t less than or equal to M
Step-by-step explanation:
It is given that compound A decays at a rate of 12% per week, and compound B decays at a rate of 18% per week. Since the rates represent decay, the r-value is negative. A decay rate of 12% is represented by an r-value of -0.12, and a decay rate of 18% is represented by an r-value of -0.18.
The initial amount of compound A is 30 grams and the initial amount of compound B is 40 grams. Substitute the initial amounts of each compound and their respective decay rates into the system of inequalities.
The following system of inequalities can be used to determine when the remaining mass of the two compounds, M, will be the same, after t weeks.
Subtract 12 from both sides
-12 = v
Hope this helps!
Answer:
4x - 7y = 19
4(-4) - 7(-5) = 19
-16 - (-35) = 19
-16 + 35 = 19
19 = 19
(-4,-5) is a solution to given equation.
4(9) - 7(6) = 19
36 - 42 = 19
-6 ≠ 19
(9,6) is not a solution to given equation.
4(1) - 7(-3) = 19
4 - (-21) = 19
4 + 21 = 19
25 ≠ 19
(1, -3) is not a solution to given equation.
4(-6) - 7(2) = 19
-24 - 14 = 19
-38 ≠ 19
(-6,2) is not a solution to given equation.

<h2>Task:</h2>
- Draw a poster that symbolizes-the importance of grammatical signals in developing patterns of idea in communiting to your readers. You will be graded according to the rubrics provided. An example is provided as your guide.
<h2>Answer:</h2>
<h2><u>Zipper</u></h2>
- Using grammatical signals in developing patterns of idea can be like a zipper; because it zips our ideas or combined some informations that we have into one which helps readers understand our message better.
<h3>What is Gramatical signals?</h3>
- <u>Grammatical signals</u> are writing devices that serve to maintain text coherence. Short story is one of written medium where we can find these signals.
<h3>Why Gramatical signals important?</h3>
- <u>Gramatical signals</u> is important because they signal relationship between sentence by means of back reference through the using of pronominal forms, determiners, repetition of key words, ellipsis, parallelism, synonyms and superordination. In short, they signal the relationship between new sentences and the one before it and they are also the important writing devices in text construction.
