Answer:
The initial value of the function is 25 and the rate of change is - 5.
Step-by-step explanation:
The table gives the ordered pairs of linear relation and they are (1,20) and (3,10).
Now, the equation of the linear relation that includes those ordered pairs will be
⇒ y - 10 = - 5(x - 3)
⇒ y - 10 = - 5x + 15
⇒ y = - 5x + 25
Therefore, the initial value of the function is 25 and the rate of change is - 5. (Answer)

Just calculating the differential. Step by step:

If you want to know where the tangent has no slope:
So, 50/100 can be simplified to 1/2 (a half). Therefore, the decimal notation for 1/2 would be .5 (This is just one of many ways to solve this type of problem) Hope this helps, let me know if you need more help : )
Answer:
Quon is right
Step-by-step explanation: 2x3=6 square in not 2.4 square in
Answer:
15 two-point questions and 5 four-point questions.
Step-by-step explanation:
Let x represent number of two-points questions and y represent number of four-points questions.
We have been given that Janice wants to create a test containing 20 questions. We can represent this information in an equation as:

Since all questions are worth 50 points. We can represent this information in an equation as:

From equation (1), we will get:

Upon substituting this value in equation (2), we will get:







Therefore, there are 5 questions that are worth 4 points each.
Now, we will substitute
in equation (1) to solve for x.



Therefore, there are 15 questions that are worth 2 points each.
