Can somebody explain how to get the answer/ what formula, and the answer??

9 cm

Step-by-step explanation:

divide the total circle centimeter which is 18 in half. Half of 18 is 9 so the diameter is 9.

R = 9 cm

Step-by-step explanation:

C = 2ПR

Also C = 18П сm

2ПR = 18П

R = 18П/2П = 9 сm

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
