The tree in Teresa's backyard is 9.5 m high. How high is it in cenimeters?

950cm

Step-by-step explanation: the metrric system is based on 10 so you just have to multiply 9.5 by 100 then yot get your answear

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:

yes   because as the functions are graphed they eventually will intersect unless otherwise
