5x - 8 + {6x – [3(x + 8) + 6]} = 6(x + 5)

x=28

Step-by-step explanation:

PEMDAS

parenthesis first...

5x-8+(6x-3x-24+6)=6x+30 *remember to distribute the negative sign*

5x-8+(3x-18)=6x+30

8x-26=6x+30

2x=56

x=28

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.
