Answer:
10+14c
Step-by-step explanation:
You multiply every number inside the parenthesis by 2.
Answer:
=4x-2
Step-by-step explanation:
f=x, h=4x-2, f(x) *h(x): 4x-2
We have the following equation:
x2 + y2 + 6y - 72 = 0
Rewriting we have:
x2 + y2 + 6y = 72
Complete squares we have:
x2 + y2 + 6y + (6/2) ^ 2 = 72 + (6/2) ^ 2
x2 + y2 + 6y + (3) ^ 2 = 72 + (3) ^ 2
x2 + y2 + 6y + 9 = 72 + 9
x2 + (y + 3) 2 = 81
So, the center is:
(0, -3)
The radio is:
r = 9
Answer:
(0, -3)
r = 9
Y= 2x-3
the slope of the line is 2, and b, the y-intercept, is -3
