Answer:
Step-by-step explanation:
Express with a positive exponent
1/12^2
Evaluate the power 12^2 =144
Final answer
1/144
Step-by-step explanation:
1-(2x+4)= 1-2x-4= -2x-3
Answer:
This means the center is (-3,-8) and the radius is 9
Step-by-step explanation:
(x+3)^2 + (y+8)^2 = 81
The equation of a circle can be written as
(x-h)^2 + (y-k)^2 = r^2 where the center is (h,k) and the radius is r
We can rewrite the above equation as
(x- -3)^2 + (y - -8)^2 = 9^2
This means the center is (-3,-8) and the radius is 9
