Answer:
0,1,2,3,4,5
Step-by-step explanation:
You can not buy more than 5 books because you'd have a negative amount of money. So 0,1,2,3,4,5 are the possible values for b.
It's a glitch I believe (screenshot and contact your teacher)
One way to carry out this problem is to simply take the value that you already know, which is that 1/5 is 20 % and multiply it by 2 for 2/5 or 2 (1/5ths) and do this for all of them. There is a pattern that occurs for every increase in one out of denominator of 5.

You have a typo in your equation. For this type of quadratic equation, it always starts out with a negative coefficient of the t squared term.
To find the x-coordinate of the vertex, we just need to use the expression: -b/2a.
Then, we have:
-24 / (2(-4))
-24 / -8

We are given that Peter buys 12 bunches of bananas for 9.00.
We need to determine how much peter will pay for 8 bunches.
Let us set up proportion now.
12 bunches of bananas for 9.00 = 12 : 9
Let us assume Peter will pay for 8 bunches = $x.
Therefore, 8 bunches of bananas for x = 8 : x.
<h3>Setting up proportion:</h3><h3>

</h3>
On cross-multiplying, we get
12x = 9×8
12x = 72.
Dividing both sides by 12, we get

x=6.
<h3>Therefore, Peter will pay $6 for 8 bunches.</h3>
