Do u know number don’t know what it is but it’s not a

B.

Step-by-step explanation:

What you want to do, is 65,470.5 - 3,219.2.

65,470.5

-  3,219.2

(Go from right to left)

1. 5-2=3

2. 0-9 isn't possible in this case, so borrrow 1 form 7. 7 becomes 6, and 10-9=1.

3. 6-1=5

4. 4-2=2

5. 5-3=2

6. 6-0=6

7. Carry down the comma and the decimal. You then get: 62,251.3, which is B.

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.

step-by-step explanation:

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
