It is either a or d maybe if wrong sorry
Answer:
10
Step-by-step explanation:
Standard form for a circle is
(x - h)² + (y - k)² = r²
where (h, k) is the center and r is the radius
--------------------------------
x² + y² - 18x + 24y = -200
Rearrange
(x² - 18x) + (y² + 24y) = -200
Complete the square for x
(x - 9)² + (y² + 24y) = -200 + (-9)²
Complete the sqaure for y
(x - 9)² + (y + 12)² = -200 + (-9)² + 12²
(x - 9)² + (y + 12)² = 25
Now the equation is in standard form
r² = 25
r = 5
Therefor Diameter = 10
Part A:
For a table to be considered a function, every x-value must have one y-value.
Each x-value in this table is unique, and has only one y-value, so this table
does represent a function.Part B:
Plug in 7 for every x in the relation:

The table's output when x = 7 is 11. Compare the two outputs:
11 < 27
The relation, 2x + 13, has a greater value when x = 7.
Part C:
Set the relation to equal 75:

Subtract 13 from both sides:

Divide both sides by 2 to get x by itself:

The x value that produces an output of 75 will be
31.
Combine multiplied terms into a single fraction
-3/7m=12
-3m/7=12
Multiply all terms by the same value to eliminate fraction denominators
-3m/7=12
7x-3m/7=7x12
Cancel multiplied terms that are in the denominator
7x-3m/7=7x12
-3m=7x12
Multiply the numbers
-3=7x12
-3m=84
Divide both sides of the equation by the same term
-3m=84
-3m/-3=84/-3
Simplify
Cancel terms that are in both the numerator and denominator
Divide the numbers
m=-28
8n+16
the four odd numbers are 2n+1, 2n+3, 2n+5, 2n+7
2n+1+2n+3+2n+5+2n+7=8n+16
