Answer:
center= (0, -9)
r=1
Step-by-step explanation:
formula for circle= (x-h)^2+(y-k)^2= r^2
(h, k)= center
r= radius
We know that h is 0 since (x-h)^2 is x^2.
We know k= -9 from (y+9)^2
since r^2=1
r=1
You can't do anything because they aren't the same term
Answer:
6
Step-by-step explanation:
-4x -3 = -6x +9
-4x = -6x +12
2X = 12
x = 6
Answer:
she made electronic calculating machines in order to calibrate rockets and make everything more precise
Step-by-step explanation:
165/3=55 mph
650/55=h
650/(165/3)=h
(650*3)/165=h
3/165=h/650
h/650=3/165
so it is the third option
