Anumber has the digits 2, 5, and 4 to the nearest 100, the number rounds to 200 what is the number

245

Step-by-step explanation:

To be closest to one hundred you need to put your smallest number as the first digit. To make sure it rounds down you need to be less than 50 so 245.

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

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.
