If the relation can be represented by the equation IR = 12, rewrite the equation in function notation so that the resistance R is a function of the current I. What is the resistance in a circuit when the current is 0.5 ampere?

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:

c

step-by-step explanation:

wait this depends wether emily and zach how they are thinking.

yes they are the same.

y - 25 = 2 ( x - 10 ) should be the answer
