Solve for x. 3 4 x + 1 4 (x + 12) − 12 = 4x − 21
a) −3
b) 3
c) 4
d) 6

47

Step-by-step explanation:

34x+14x

+168-12=4x-21

34x+14x+156=4x-21

Collect like terms

34x+14x-4x=-21-156

44x=-177

Divide both sides by 44

-4

stethere all not eveanp-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.
