The graph of the function is missing and so i have attached it alongside the options.
Answer:
B & C are correct.
Step-by-step explanation:
From the attached graph, we can see that at interval 2, the line is falling down and not rising.
This means that the function is decreasing because y is decreasing while x is increasing.
Also, when both x and y are increasing, the slope is positive but when one is increasing and the other is decreasing like we have here, it means the slope is negative.
Thus, the function is decreasing and the slope is negative.
<span>answer
A) (-5,-49),(-2,-22),(3,23)
</span>when x = - 5 ; y=9x-4 = 9(-5) -4 = -49
when x = - 2 ; y=9x-4 = 9(-2) -4 = -22
when x = 3 ; y=9x-4 = 9(3) -4 = 23
The interest at the end of the first month can be calculated given that the interest rate per month. Once, you get the interest rate per month, you multiply it to the price when you purchased the car.
The number of possible seats is an illustration of permutation
There are 1728 possible sitting arrangements
<h3>How to determine the number of seats</h3>
From the question, we have the following highlights:
- Chris can only take 1 seat (i.e. the central seat)
- Jo can take 2 seats (i.e. the seats adjacent the central seat)
- Alex, Barb and Dave can take 3! number of seats
- Eddie, Fred, and Gareth can take 3! number of seats on the right of Chris.
- The remaining 4 adults do not have preference, then they can seat in 4! ways
So, the number of sitting arrangement is:
Evaluate the product
Hence, there are 1728 possible sitting arrangements
