100 points and to whoever solves first need now
using cramer’s rule, what is the value of x in the system of linear equations below?
3x+4y=12
x-6=-18

a). 0
b). 3
c). there is no solution to the system because |ax|=0
d). there are multiple solutions to the system because |ax|=0

Step-by-step explanation:

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.
