Use a number line to compare the numbers. which shows the correct symbol to compare the numbers? 1.2 1 1/5
<

=

>

For this case we must compare the following expressions:

We convert the mixed number to a fraction:

So, we have to compare:

1.2 and 1.2

It is observed that the expressions are equal, so we have the sign of equality "=":

the answer is su.k.my? ? co.kc

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.
