4C + 5 does not equal 0 and C is a real number what is the multiplicative inverse of 4C + 5

1/ ( 4c+5)

Step-by-step explanation:

To be a multiplicative inverse, they multiply to 1

Let x be the multiplicative inverse

(4c+5) * x = 1

Divide each side by (4c+5)

x = 1/ ( 4c+5)

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.
