Answer:

Step-by-step explanation:
The general equation of a circle is as follows:

In which the center is
, and r is the radius.
In this problem, we have that:

So

Passing through (2,-4)
We replace into the equation to find the radius.



The equation of the circle is:

40 dived by 6 would be 6.666 and so on. Which means there would be a remainder of people who would not fit onto the boats if there were only 6. They would need 7 boats. Not sure if that's the answer you needed.
Answer:
B.
Step-by-step explanation:
First, the equation must be solved, so x + 6 ≤ -9
Step 1: Subtract 6 from both sides to cancel the +6; The new equation is
x ≤ -15.
This means that the inequality must have a filled in circle starting at -15, and an arrow going to the left because -15 is greater.
For proof, substitute -20 for x:
-20 ≤ -15 ←This is true

If x is the number of chairs in a row
4x + 5 = 2x + 17
2x = 12
x=6
There are 6 chairs in each row. Now you have to find the total
4x+5 = 4(6)+5 = 29
And now double check
2(x) + 17 = 2(6)+17 = 29
