(x-h)^2+(y-k)^2=r^2
center is (h,k)
radius is r
means that ny point, r units from (h,k) is on it
means that the points (h+r,k) and (h-r,k) and (h,k+r) and (h,k-r) are defenitely on the circle
given
(x-2)^2+(y-(-3))^2=2^2
center is (2,-3)
radius is 2
points on it are
(4,-3) and (0,-3) and (2,-1) and (2,-5)
there are more, but these are 4 that are defenitely on it
Answer:
The slope of the line that passes through the points (-20,18) and (30,14) is
m (slope) = -2/25

Answer:
15.75 boxes
Step-by-step explanation:
you divide 10.5 to get 1/3 of the floor, then multiply that answer by 3 to get the whole floor
Answer:
The number is -40
Step-by-step explanation:
-40+12=-28
-28/4=-7
Answer:
Option 3
Step-by-step explanation:
the symbol your question is showing is "greater than or equal to"
when a line includes "or equal to", the circle will be filled in. also, since the symbol is going towards 5, it is considered a greater than symbol. so, you'd want to choose the option with a filled in circle and an arrow pointing to the right.
since option 3 has a filled in circle and has its arrow pointing towards the positive (or right) side of the line, it should be option 3.
